Question

Gravity causes the metal in the arc to fall as it travels across the arc. What can be done to minimize this effect while welding in the horizontal, vertical, or overhead positions?

Answer 1

To minimize the effect of gravity while welding in different positions, techniques such as controlling travel speed and weld pool size, and using uphill or backhand techniques, can be employed.

Step-by-step explanation:

To minimize the effect of gravity on the metal while welding in different positions, certain techniques and equipment can be used. In horizontal welding, a slower travel speed and a smaller weld pool can help minimize the effect of gravity. In vertical welding, a technique called uphill welding, where the weld is made against the force of gravity, can be used. In overhead welding, a backhand technique, where the weld is made in the opposite direction of gravity, can reduce the impact of gravity. Additionally, using positional welding techniques and fixtures can help maintain control over the molten metal and prevent it from sagging or falling due to gravity.
