Types of Welding

Welding is a joining process that produces coalescence, or merging together, of materials by heating, with or without the application of pressure, or by the application of pressure alone, and with or without the application of filler metal. The primary difference between welding and other joining techniques such as soldering is that the material of the parts is melted to facilitate a molecular bond between parts. This allows for a joint that is as strong or stronger than the component materials being joined. Welding is the most efficient method of permanently joining metal.

Types of Welding

Depending on the material and intended product application, there are a variety of different types of welding. Each method uses different tools, heat sources, materials, or equipment to produce the desired results. Below is a short summary of the most common welding methods. 

MIG Welding

Metal inert gas (MIG) welding, also known as gas metal arc welding, involves creating an electric arc between a consumable wire electrode and the workpiece. The wire is continuously fed into the arc, allowing it to melt and serve as the filler metal for joining the two workpieces together. Throughout the process, the weld pool is protected from contamination through the use of a shielding gas.

Pulsed MIG Welding

Pulsed MIG welding is a variant of conventional MIG welding that involves pulsating the electric current rather than having a steady amperage. This process ensures low levels of spattering and is compatible with a variable working range from light gauge to thick gauge sheets.

Low Splatter Control (LSC) Welding

LSC welding is a type of MIG welding that offers high-quality weld seams with high arc stability, minimal spattering, and an increased deposition rate. This process uses a penetration stabilizer, which enables constant penetration in the spray arc, even with possible stick out change.

Pulse Multi Control (PMC) Welding

PMC welding is another type of MIG welding that relies on a modified pulsed arc. This method utilizes arc length and penetration stabilizers to ensure faster welding speeds and higher quality weld seams.

Cold Metal Transfer (CMT) Welding

CMT welding offers very low heat input and an extremely stable arc, regardless of weld speed or the surface of the workpiece. This ensures optimum results when joining different materials such as aluminum and steel. This method also features reversing wire electrode movement, which reduces the amount of spattering.

TIG Welding

Tungsten inert gas (TIG) welding, also called gas tungsten arc welding (GTAW), creates a weld using a non-consumable electrode to generate an electric arc and a filler metal. An inert shielding gas is used to protect the electrode and weld area from contamination. Since the welding operator must carefully guide the electrode and filler metal, this process allows for more control and precision compared to other welding methods. 

Stick Welding

Stick welding is a simple method that uses a consumable electrode rod that melts and bonds with heated material to join two components. It creates bonds even with rust and unclean surfaces, making it ideal for outdoor construction. Since an inert gas envelope is not produced for stick welding, the welds may exhibit oxidation and porosity.

Flux Core Arc Welding (FCAW)

Flux core arc welding (FCAW) is very similar to MIG welding in that it uses a continuous filler wire electrode to create an arc. However, the electrode used in FCAW processes is a hollow tube filled with flux that outgasses when heated. Similar to the inert gases in MIG and TIG welding, this flux outgassing protects the weld from exposure to atmospheric oxygen, thereby creating strong, reliable weld joints.
