Learn the basics of welding and more

Arc welding is a fabrication process that uses an electric arc, which is formed between the electrode or filler wire and the workpiece to join the metals being welded. The source of heat is produced by a power source. When welding, a filler metal is usually needed. Two types of filler metals commonly used in arc welding are welding rods and electrodes.

Today, there are various arc welding processes that have their own applications. The most common types of arc welding are stick welding (MMA), MIG/MAG welding (GMAW), and TIG welding (GTAW). Arc welding processes may be manual, semi-automatic, mechanized, or automated.

Discover welding processes

MIG/MAG welding

MIG/MAG welding

MIG/MAG welding is a welding process where filler wire is fed at a set speed through a welding gun into a weld pool shielded with shielding gas.

TIG welding

TIG welding

TIG welding is a manual welding process that involves feeding the filler wire by hand into the weld pool shielded with shielding gas.

Stick welding

Stick welding

Stick welding, also known as manual metal arc welding (MMA welding) or shielded metal arc welding (SMAW) is a manual arc welding process where an electric arc is struck between a metal electrode and the workpiece.

Robotic welding

Robotic welding

Robotic welding or automated welding automates the welding process. Robotic welding can be used in several welding processes like in MIG and TIG welding.

Other welding methods

Other welding methods

Other, more uncommon welding processes, such as MIG brazing and laser, submerged, plasma, spot, friction, and explosion welding.

All you need to know about welding

What is welding?

What is welding?

Welding is a fabrication process where materials, usually metals are joined using heat and/or compression so that the pieces form a continuum.

Welding safety and welding hazards

Welding safety and welding hazards

Welding safety consists of several factors. For example welding fumes and ultra-violet radiation cause a health risk if a welder doesn't use appropriate personal protection equipment.
