TIPS FOR TIG WELDING ON STAINLESS STEEL
1. Proper fit up :Proper fit up ensures that only the required amount of filler metal is used.
2. Filler metal :The thicker the rod or wire the more heat is required to melt it.
3. Electrode size :Common tungsten electrode sizes range from 3/32 to 1-1/4 of an inch
4. Electrode geometry :A taper of no more than 2.5 times the electrode diameter creates a focused arc capable of producing deep, thin beads, and a narrow heat-affected zone
5. Fingertip and foot control :A foot control allows for a more precise control of amperage and doesn’t interfere with your torch hand.
6. Puddle size :The weld puddle should be the thickness of the base metal.
7. Gas flow and travel speed :Keep the gas flowing and directed at the puddle until the orange color fades.
8. Polarity and pulsing :Use pulsed gas tungsten arc welding with a direct current electrode negative current
