In the context of MCAW fill passes, which inclination description is correct for 2G?
Correct Answer:
Forehand 0° - 10°
Explanation:
In a 2G horizontal groove weld, you’re welding on a vertical plate with the bead laid horizontally as you move the torch left to right. The torch should be angled slightly forward toward the direction of travel (forehand). Keeping a small forward tilt, about 0 to 10 degrees, gives you better control of the molten pool on the horizontal plane, promotes proper wetting into the joint, and helps build a uniform bead for MCAW fill passes. A backhand approach tends to pull the puddle away from the joint and can cause a less stable bead, while a sideways tilt (and certainly a vertical tilt) disrupts control on a horizontal weld. So the best choice for 2G MCAW fill passes is forehand with a 0–10 degree inclination.
