What is the best torch angle for flat welding?

• A. 10-15° push angle
• B. 45° push angle
• C. 0°
• D. 20-30° pull angle

Answer: (A)

Torch angle controls shielding gas coverage and how the molten pool behaves in TIG welding. For a flat-well position, a light forward push of about 10-15 degrees keeps the shielding gas directed down onto the weld pool, stabilizes the arc, and helps produce a consistent bead profile. A much steeper angle, like 45 degrees, pushes the gas and arc too far ahead and can distort the bead and reduce shielding effectiveness. No angle (0 degrees) often leads to poorer gas coverage and porosity. Pulling the torch at 20-30 degrees changes the gas flow and arc direction in a way that typically isn’t ideal for flat welding, risking an irregular bead and weaker shielding. So, a small forward push of 10-15 degrees best balances shielding, arc stability, and bead control in the flat position.
