Inclination is relative to which reference in welding?

• A. Direction of travel
• B. The joint to be welded
• C. Heat source
• D. Reference line

Answer: (A)

Inclination is about how the electrode or torch is tilted relative to the path you’re moving along the joint. The reference is the direction of travel—the angle is described in terms of forward or backward tilt with respect to that travel direction. This matters because the travel angle controls how the molten metal is deposited, shaping the bead and affecting penetration. Tilting toward the direction of travel tends to push metal ahead into the weld pool, while tilting away changes how the puddle feeds and can alter fusion. The joint itself or the heat source aren’t used as the reference for this angle.
