What is TIG welding?
TIG welding is a precise arc-welding process that uses a non-consumable tungsten electrode and shielding gas, usually argon.
Is TIG welding difficult to learn?
TIG welding takes practice because it requires coordinated torch, filler rod, and foot-pedal control, but beginners can learn the fundamentals step by step.
What will I learn in a How To TIG Weld course?
You will learn machine setup, safety, torch angles, arc control, filler-metal use, and basic weld techniques.
How do I make clean TIG welds?
Clean TIG welds require properly cleaned metal, adequate shielding gas, the right tungsten preparation, and steady torch movement.
Why is torch control important in TIG welding?
Good torch control maintains a consistent arc length and travel speed, helping create even, strong, and attractive weld beads.
When should I use filler rod in TIG welding?
Use filler rod when the joint needs added material for strength, gap filling, or bead reinforcement; some thin joints can be fusion welded without it.
What materials can I TIG weld?
TIG welding is commonly used for stainless steel, mild steel, aluminum, chrome-moly, copper alloys, and other thin or precision metalwork.
