What is a welding torch used for?

A welding torch is a core handheld tool for metal fusion welding,delivering welding current,shielding gas and welding wire to the weld joint to melt and join metal workpieces.Its main application scenarios vary by torch type:

MIG/CO₂welding torches(air/water cooled)

Cooperates with wire feeders to automatically feed solid welding wire.It is widely used for welding carbon steel,stainless steel and aluminum in steel structure manufacturing,auto repair,metal fabrication and machinery processing.

TIG/GTAW welding torches

Uses tungsten electrodes for precise,clean welding.Ideal for thin sheets,stainless steel,aluminum alloy and high-precision crafts,pipeline and aerospace fabrication.

Stud welding torches

Specialized for auto body dent repair and fastener stud welding on metal panels in vehicle maintenance.

Plasma cutting torches

Generates high-temperature plasma arc to cut all conductive metal plates.

Besides welding forming,welding torches also undertake auxiliary functions:metal heating,rust removal,post-weld heat treatment and metal surface shaping.Different cooling structures(air-cooled for light duty,water-cooled for heavy continuous high-current welding)match different industrial workload demands.
