What are the typical welding positions and how does bead direction and electrode angle change with position in TIG?

• A. Flat, horizontal, vertical, overhead; electrode angle around 5–15 degrees off-axis in flat; increases slightly for vertical or overhead to maintain puddle control.
• B. Positions: flat only; angle constant 45 degrees
• C. Only overhead; angle 90 degrees
• D. Position irrelevant; angle always 0 degrees

Answer: (A)
