Welding Processes Explained

Multi-process welders are versatile machines that allow welders to switch between different welding processes such as MIG, TIG, stick, and flux-cored welding. Each process has its unique characteristics and applications. In this section, we will explore each of these processes and their features.

MIG Welding

MIG welding is a welding process that uses a consumable wire electrode and an inert gas to protect the weld from atmospheric contamination. The wire is fed through a spool gun or a wire feeder, and the welder controls the amperage and voltage settings. MIG welding is known for its speed, versatility, and ease of use. It is commonly used in automotive, fabrication, and manufacturing industries.

TIG Welding

TIG welding, also known as Gas Tungsten Arc Welding (GTAW), uses a non-consumable tungsten electrode to produce the weld. The welder controls the amperage and voltage settings, and a filler metal is added manually. TIG welding produces high-quality, precise welds, and is commonly used in aerospace, automotive, and artistic applications.

Stick Welding

Stick welding, also known as Shielded Metal Arc Welding (SMAW), uses a consumable electrode coated in flux to produce the weld. The welder strikes an arc between the electrode and the workpiece, and the flux creates a shield to protect the weld from contamination. Stick welding is versatile and can be used in outdoor and remote locations. It is commonly used in construction, maintenance, and repair industries.

Flux-Cored Welding

Flux-cored welding is a welding process that uses a tubular wire filled with flux to protect the weld from contamination. The wire is fed through a wire feeder, and the welder controls the amperage and voltage settings. Flux-cored welding is versatile and can be used in outdoor and remote locations. It is commonly used in construction, fabrication, and manufacturing industries.

In addition to these welding processes, some multi-process welders also offer pulsed MIG welding. Pulsed MIG welding is a variation of MIG welding that uses a pulsed current to reduce heat input and produce a more precise weld. It is commonly used in automotive, aerospace, and manufacturing industries.
