Arc Welding: Everything You Need to Know
Want to choose the best arc welding machine? Begin by understanding what is meant by arc welding. The selection process will become much easier once you grasp the basics. Popular across a wide range of industries, welding finds application in automotive and construction as well as shipbuilding and metal fabrication. The different forms of welding are suitable for different applications. So, here we’ll simplify it all for you.
From what is the meaning of arc in welding to different types of arc welding, scroll to enlighten yourself with all that you need to know.
What is the Meaning of Arc Welding?
Let’s begin with what is meant by arc welding.
Welding is the process of joining two metals together. It requires high heat to melt the metals, which are further fused together upon cooling. This source of heat can be provided through a variety of methods.
Among them, arc welding is the type that uses an electric arc formed between the electrode and the workpiece to produce intense heat. The arc generates a plasma column (high temperature area) that ranges between 3,500 and 15,500 degrees Celsius. It provides enough temperature to melt the metals. The electrode used in arc welding can be consumable or non-consumable.
Arc Welding With a Consumable Electrode
Consumable electrodes melt during the process to fill in the gaps of the metal to be welded. It is further of multiple types, such as:
Gas Metal Arc Welding (GMAW)
Gas is used in this type of arc welding. It helps prevent the reaction of molten metal with the atmosphere. Thus, the gas acts as a shield. The electrode melts to act as filler material for welding purposes. Different types of gases can be used here, and the arc welding process is named accordingly.
For instance, metal inert gas (MIG) arc welding uses inert gas helium, argon or a mixture of both. Another example is metal active gas (MAG) arc welding, which uses carbon dioxide for the process.
Flux Cored Arc Welding
This type of welding uses a special, flux-cored wire. It has a metal tube filled with ‘flux’ material. As the wire melts, the flux protects the weld from air, thus preventing rusting or weak joints. The flux-cored arc welding is of two types, self and gas shielded. Self-shielding depends on its own flux and slug system to protect the molten metal. Gas shielding uses external shielding gas to impart arc protection.
Electroslag Welding
This method uses a molten slag pool for heat generation and fusion of thick metals. This method is also suited for vertical or near-vertical positions. Electroslag welding is based on slag to generate heat and protect the weld. The consumable electrode serves its function of melting and becoming the filler metal.
Arc Welding With a Non-Consumable Electrode
Non-consumable electrodes are used solely to generate the arc and not for melting or becoming a part of the welding process. There are the following types in here:
Carbon Arc Welding
It was the first arc welding to be discovered and hence was also the most commonly used one. It uses a non-consumable carbon electrode to form an arc and weld the metals. The use has witnessed a decrease owing to the presence of modern, efficient and safer techniques.
Tungsten Inert Gas Welding (TIG)
This method uses a non-consumable tungsten electrode and inert shielding gas for the welding process. The presence of filler material depends on the requirement. These electrodes come with longer life, lead to very high energy density for welding and offer better arc stability. They are also top quality due to their contamination resistance.
TIG welding is technical and requires practice to master the process. It is a time-consuming process and inefficient for thick metal joints. But results in high-quality, strong and clean welded products.
Atomic Hydrogen Welding
In this case, the arc is created between two tungsten electrodes within a hydrogen gas environment. The elevated temperature in the arc dissociates hydrogen molecules into atomic hydrogen, which subsequently recombines, generating an additional significant amount of heat for welding. It is also a technical process that requires experience. The atomic hydrogen arc welding process is also expensive, suitable only for flat positions, and risky due to the use of highly inflammable gases.
What is the Meaning of Arc in Welding? How is it Created?
An arc refers to the flow of electric current comprising high-speed electrons between two points. The one end is the electrode, and the other is the base material. The electrode end has excess electrons and hence is negatively charged, while the base material end has few electrons and hence is positively charged. This change in voltage creates a potential difference, leading to a flow of electrons.
Further, high voltage also ionises the gas, turning it into plasma due to heat. The plasma serves as a conducting path or medium for the flow of electrons. This process is referred to as dielectric breakdown. It can result in a quick flash or spark that results in a burning arc.
How Does Arc Welding Work?
Arc welding is based on fusion welding. Here is a step-by-step breakdown of how the process works:
Step 1: The welding machine is switched on with AC or DC power, a cable, an electrode holder and the electrode.
Step 2: The power source generates a voltage difference, forming an arc with extremely high temperature.
Step 3: The arc at high temperature melts the base metals to be joined or melts the consumable electrode and fills it in the gap to be welded.
Step 4: The arc proceeds forward to weld subsequent gaps, which can be manually or mechanically guided. The previously welded parts cool off, solidify, and are joined to form the metallurgical bond.
The metal heating process frequently results in chemical reactions with oxygen and nitrogen present in the air. This obstructs the welding procedure and diminishes the quality of the welded item. To safeguard against this reaction, a protective shielding gas or slug is employed to reduce the interaction between molten metal and air
Conclusion
Arc welding is a versatile metallurgical bond formation process. With a variety of consumable and non-consumable arc welding processes, it fits into diverse needs. The advanced approaches with seamless metal bonding are also available with better safety control. Are you in the middle of your product search and confused about how to proceed?

How is MCB Superior to the Fuse Wire
Do you know that damage might occur to your electrical equipment by short circuits or overloads and may even result in fire? But worry not because a fuse or MCB is here to protect your electrical equipment from such mishaps. Hence, during an overload in your electrical circuit, an MCB or a fuse breaks down the electricity flow, which results in breaking the circuit.
In this article, you will acknowledge the advantages of an MCB over fuse wire and delve into the major factors of differences between them.
What is an MCB?
An electromechanical device crafted to offer protection to an electric circuit from exceeding current load, or short circuit, is called a miniature circuit breaker. This does not get damaged while facing an over-current and is reusable. They offer convenience and easy-to-use functionality. They are safer to access because they are covered in a plastic casing. The three principal characteristics of an MCB are the tripping curve, Amperes and poles.
What is a Fuse Wire?
An electrical fuse is a melting point of copper or any other metal wire that gets damaged and breaks because of the heat generated by high load or over voltage to avoid failure to the device or a short circuit. This device acts as a barrier between the electrical circuit and the human body. Hence, it is a safety device protecting electrical circuits from the mis-happenings that might occur due to excessive current load.
Advantages of Fuse Wire: Why Choose MCB?
The major problem that arises with a fuse is that during the situation of overloading, the fuse wire melts down and needs replacement to complete the circuit. However, this is not the issue with miniature circuit breakers. It turns off automatically whenever a situation of a short circuit or overload occurs. When the problem in the circuit is resolved, the switch can be turned on again, and the current starts flowing as usual.
Some other major advantages of MCB over a fuse are:
- A MCB is competitively more sensitive to current over a fuse. Hence, an MCB can detect abnormal conditions in the current flow, give a faster response over hazards and automatically switch off the electrical circuit.
- With a modern circuit breaker, identifying faulty areas in the electrical circuit is straightforward. However, when using a traditional circuit protection device, you must inspect the entire element to pinpoint the faulty areas.
- You can easily resume supply with an MCB as it offers ease of setting. All you need to do is push the MCB knob to the on position. However, when using a fuse, you have to replace the entire fuse wire.
- As compared to a fuse, you get more safety with MCB, and it offers a longer lifespan. While functioning an MCB, you are not exposed to the electrical parts directly. However, when replacing the fuse, there are more chances that you come in direct contact with a current-carrying conductor or a live wire.
- An MCB has lesser replacement and maintenance costs as it can be reused. However, you cannot use a fuse again once it is damaged.
- Miniature circuit breaker comes in a small size, which can be easily moved and handled.
- A MCB provides immediate protection and takes action quickly against overload conditions, overheating, and short circuits.
- As compared to a fuse, a miniature circuit breaker offers a better interface for abnormal and normal situations.
Difference Between an MCB and a Fuse
Fuses and circuit breakers provide the common purpose of protecting against electrical hazards, but they are different in operation, construction, usage, and cost, among other factors.
Construction
The construction of a traditional circuit protection device and a modern circuit breaker differs significantly. The traditional device contains a thin wire that melts under excessive current, disrupting the flow and causing the device to trip, thus opening the circuit. In contrast, modern circuit breakers utilize electromechanical mechanisms, including magnetic and thermal components, to isolate circuits in case of a fault. While traditional devices are relatively straightforward, modern circuit breakers feature a more complex design with multiple components that improve sensitivity to current fluctuations.
Operation
The key difference between fuses and miniature circuit breakers lies in their operation. They depend on a metal wire that melts, disrupting the circuit during an overload or short circuit. Conversely, miniature circuit breakers trip by using a bimetallic strip, a solenoid, or a combination of both when the current exceeds the designated level, effectively opening the circuit to safeguard the electrical system.
They consist of a metal wire with a low melting point placed between two metal caps, facilitating easy melting in the event of increased current. In contrast, miniature circuit breakers employ different mechanisms to safely isolate circuits under overload or short circuit conditions.
Cost
A notable contrast between modern circuit breakers and traditional circuit protection devices lies in their cost. Traditional devices are more affordable than modern circuit breakers due to their simpler construction. However, long-term expenses can favor modern circuit breakers, as the recurring cost of replacing a traditional device might exceed the cumulative cost of modern circuit breaker devices. This is because traditional devices require a new purchase with each trip, whereas modern circuit breakers can be reused after tripping.
Use
Fuses and miniature circuit breakers serve distinct purposes with varying benefits. While a blown fuse necessitates replacement, an MCB can be reused after tripping, eliminating the need for frequent replacements. This usage characteristic makes MCBs a preferred and more convenient option compared to fuses in most cases.
Variety
Miniature circuit breakers (MCBs) offer a broader range of options compared to fuses. MCBs come in various trip curves, voltage ratings, current ratings, interrupting capacities, and sizes, providing greater flexibility to meet specific requirements. In contrast, fuses are limited to two types: fast-blow and slow-blow, reflecting the simpler operation of fuses compared to the versatility of MCBs. Also read

MCB vs ELCB: Key Differences, Functions & Applications
MCB and ELCB are two different things that serve one common purpose, and that is to ensure electrical safety. Now, you might be thinking that these two terms are almost the same, but in reality, they possess significant differences. Want to learn about the difference between MCB and ELCB? You are at the right place. Read through this blog to get a better understanding of the ELCB MCB difference, function and application.
What is ELCB?
An Earth Leakage Circuit Breaker, abbreviated as ELCB, is a device that is primarily used to safeguard electrical systems by detecting earth leakages* in them. This safety device then monitors current flow in the system in order to detect leakages (to the earth). If a leakage is detected, it immediately cuts off the circuit to prevent any further ramifications.
The major use of ELCBs is protecting people from electrical shocks and stray current hazards.
| *The term earth leakage is used to describe an occurrence in which electric current unknowingly passes through a different path, causing electrical shocks or fires.* |
ELCBs can be classified into two types:
- Voltage Earth Leakage Circuit Breakers: Triggered when there is a rise in the potential between a grounded element and an electrical system.
- Current Earth Leakage Circuit Breakers: Triggered when they detect an imbalance in current between live and neutral conductors, indicating a leakage.
It is important to know that although ELCBs are effective for safety, they are gradually being replaced by RCCBs (Residual Current Circuit Breakers) as they are proving to be more advanced when it comes to protection.
What is MCB?
A miniature circuit breaker, popularly known as an MCB in simple terms, is a safety device that is used to protect circuits from overloads and short circuits. MCBs are generally used for lower current systems (typically up to 1000V) and voltage ratings in commercial and residential buildings. They are also compact and inexpensive devices that are designed to trip at the time of a fault detection in the circuit. Current ratings of MCBs can vary, ranging from a few amps to 125A.
MCB vs ELCB: Key Difference Between MCB and ELCB
This particular table highlights the MCB and ELCB difference:
| Aspect | MCB | ELCB |
| Working Principle | - Detects overcurrent (overload & short circuit).- Operates using thermal and magnetic trip mechanisms.- Does not detect earth leakage. | - Detects earth leakage current.- Works by monitoring the current imbalance between live and neutral wires.- Trips when the leakage current exceeds a safe limit. |
| Sensitivity to Faults | - Sensitive to overcurrent faults only.- Cannot detect leakage current or ground faults.- Protects appliances from fire hazards due to excessive current. | - Sensitive to earth leakage faults.- Does not protect against overloads or short circuits.- Prevents electric shocks by cutting off power when leakage occurs. |
| Usage and Applications | - Used in homes, offices, and industries for circuit protection.- Installed in distribution panels for individual circuits.- Essential for preventing wiring damage due to excess current. | - Installed in bathrooms, kitchens, and outdoor areas where the risk of electric shock is high.- Used in sensitive electrical setups to ensure human safety.- Common in industrial areas with heavy electrical loads. |
| Protection Type | - Protects against overcurrent and short circuits.- Ensures circuit integrity and prevents wire overheating.- Does not protect against leakage current. | - Provides earth leakage protection.- Prevents electric shocks and electrocution.- Does not safeguard against overcurrent issues. |
Summing Up
The major difference between ELCBs and MCBs lies in their functionalities. MCBs function to safeguard against overcurrents and short circuits in specific circuits, whereas ELCBs protect against earth leakages, ensuring personal safety. Both devices are of extreme importance in maintaining a safer environment.

Difference Between MCB and MCCB: Key Features & Uses
MCCBs and MCBs are two things that appear similar but have significant differences. Both are designed to protect electrical circuits by automatically shutting down power during electrical faults, but their usage varies based on factors like capacity, mechanisms and applications. This blog breaks down the MCB and MCCB difference. Read on to find out.
Miniature Circuit Breaker
The MCB is an automatic electrical device used to protect circuits from damage caused by increased current, such as overloads or short circuits. With a simple working principle, the MCB features movable and fixed contacts. When the current exceeds the limit set, these contacts disconnect, interrupting the circuit and preventing any possible damage. This essential element ensures electrical systems’ safety whenever problems are detected by disturbing current flow and keeping equipment from threats.
Working
Here is how MCBs work:
- They primarily function to protect the equipment from passing overcurrent.
- MCB consists of one fixed and one movable contact.
- The movable contacts are disconnected from the fixed contacts when the current exceeds its set limit, which makes the circuits open and disconnects them from the main supply.
Examples
- MCBs are mostly used to protect home and commercial property appliances and devices. These include air conditioners, refrigerators, etc.
- Electrical distribution boards also use MCBs to protect lighting and socket circuits.
- Renewable energy systems like solar PV systems use MCBs for protecting DC circuits from short circuits.
Molded case circuit breaker
A Moulded Case Circuit Breaker (MCCB) is a device used to protect circuits from overloading that can be adjusted to suit high-current applications. In contrast to the MCB, it includes a manually operated contact for tripping. It has a bimetallic contact that has two arrangements, i.e., one for over-temperature and the other for over-current.
This contact expands and contracts with temperature changes. In normal conditions, it allows current flow, but if it exceeds predefined limits, the contacts expand until they open, disconnecting the circuit. This crucial feature shields equipment from potential damage due to excessive current.
Working
Here is how MCCBs work:
- MCCBs possess two types of arrangement, one for over-temperature and the other for over-current.
- MCCB contain bimetallic contacts that expand and contract because of the changing temperatures.
- When opened, the contact usually allows the current to flow through the circuit.
- Once the current exceeds the defined limit, the contacts heat up until they disconnect. The MCCB disconnects the circuit from the main supply and protects the equipment from damage.
Examples
- You can find them in industrial applications, such as manufacturing plants, refineries, power generation facilities, and more.
- Likewise, commercial buildings, including hospitals and malls, also use MCCB to protect electrical systems against overcurrent and short circuits.
