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?
