3 Major Types of Welding Machines & Their Features

Find out the 3 major types of welding machine and their features to help with your welding projects. Understand the best welding type to use for different jobs.


#1. Metal Inert Gas (MIG) Welding

This type of welding process consists of passing a bare metal filler wire of the same material being welded through a portable torch unit in combination with shielding gas. The welding wire takes up the current supplied by a standard power source, and then the contact creates an arc, which takes over the welding. Because the wire is fed from the machine to the work-piece, the wire acts as a continuous consumable electrode, thereby requiring fewer starts and stops than others.

Especially for routine joining applications, a MIG welder is likely to offer more benefits than any other welding process.

Listed Here Are Some of The Advantages of MIG Welding:

· It is the easiest to learn the welding process as a beginner. Even with a little practice, a first-time MIG user can achieve a good-looking weld for sure.

· Able to weld light gauge material or thick plate

· It also welds all common metals, including carbon steel, stainless steel, and aluminum as well.

· Offers flexibility as welding can be performed in all positions.

· Flux removal is not necessary, as shielding is done by gas.

· Even high welding speeds can be achieved, which are up to four times faster than with stick welding, hence shortening the repair or construction time as well.

#2. Tungsten Inert Gas (TIG) Welding

The TIG welding process uses a non-consumable tungsten electrode and shielding gas, which protects the weld area from any form of contamination. Even TIG welding can be performed in all positions. TIG’s concentrated heat and precise arc control make it possible to weld thin material even as thin as 0.01 inch.

The Advantages of TIG Welding Are:

· Welding with precision for thin materials achievable and distortion is overall also reduced.

· The TIG welding process offers high-quality work which is highly aesthetic.

· It also allows the welder to make adjustments in the heat input during welding.

· Involves a fine build-up welding for moulding and tool making processes

· A single gas-argon can weld steel, aluminum, and other metals

· No splashes or fluxes to remove.

Although TIG welding is a relatively slower process than others, it at the same time offers higher weld quality than MIG or flux-cored wire process. Even to operate it, a higher qualification is required.

#3. ARC Welding:

This process involves usage of a consumable flux-coated electrode, which contains mild steel, stainless steel, cast iron, and other alloys. These electrodes are selected depending upon the base material to be welded. Equipment required includes power source, the electrode holder and the working clamp.

Below Mentioned Are Advantages of ARC Welding:

· It can be performed even in hard-to-reach places. But, considered less suitable for overhead welding work.

· It can be used outdoors.

· Almost all materials can be welded with a stick.

· Amongst other options, this is the least expensive to purchase.

· Nature is more forgiving when welding on dirty or rusty metal. However, it’s advisable to do this welding on the cleanest possible material a stronger weld result.
