Understanding the Different Types of Welding Processes

Welding may be a complex subject but it is easy to learn how to weld. It’s just a matter of how easy or as complex as you make it. Welding jobs have different requirements depending on the material to be welded, the type of filler metal, and the welding process itself. There are several types of welding processes such as Mig and Tig welds which can be used on different materials as long as the equipment is set up for the particular material.

Arc welding

The most frequently used welding processes are arc welding and gas welding, which includes Tig and Mig welding. MMA or Manual Metal Arc welding, also known as stick welding, is the oldest of welding processes still used extensively and is the best way to learn to weld. It involves the use of arc weld electrodes and uses a power supply to create an electric arc between the electrode and base material to melt metals at the welding point. It uses either direct current (DC) or alternating current (AC). The process is ideal for welding mild steel, hardened steel, stainless steel, and cast iron along with other specialty steels. Arc welding is widely used in construction and maintenance, and does not require an external gas resource.

How Do You Mig Weld

Mig or Metal Inert Gas welding is the most common process used today. Also known as GMAW or Gas Metal Arc Welding, it is one of the easiest processes to learn. If you want to learn how do you Mig weld the first thing to understand that it is basically arc welding, which uses electricity to melt and join metal pieces together with a continuous wire feed of an electrode and an external gas source. The shielding gas is fed through a welder cable with the electrode. The main components include a wire feed unit, cable, weld gun, and welding power source. Mig welding is often referred to as the ‘hot glue gun’. The arc of electricity creates a short circuit between the continuous wire feed and the metal being welded. The heat along with inert gas melts the metal and allows them to mix together and form a new piece of fused metal. This type of welding can be used with a wide range of metals and thicknesses. This includes stainless steel, copper, nickel, aluminum, and other alloys.

How Do You Tig Weld

Learning how you do Tig weld is more complex than Mig welding. Tig or Tungsten inert gas welding is a very precise process that blends reactive metals such as aluminum and magnesium together. An arc is formed between a tungsten electrode and the area to be welded. The shielding gas, which us usually argon or helium or a combination of both, ensures a higher welding speed and penetration, and helps create a clean weld. You will find plenty of tips on Tig welding to help choose the right welding rods, torch angle, techniques, and much more.
