What should be monitored to prevent excessive height of weld metal in a finished weld?

• A. Welding speed
• B. Current setting
• C. Cleaning methods
• D. Travel angle

Answer: (A)

Monitoring the welding speed is essential to prevent excessive height of weld metal in a finished weld. When the welding speed is too slow, it can lead to an accumulation of molten metal, resulting in a weld that is higher than specified. This excessive height can create defects such as poor fusion or cracking as the weld cools and solidifies.

On the other hand, while the current setting, cleaning methods, and travel angle can influence overall weld quality and bead appearance, they do not directly control the amount of weld metal deposited in the same manner as welding speed. Current affects penetration and bead shape, cleaning methods ensure proper adhesion and cleanliness, and travel angle can influence bead profile, but managing the welding speed is critical to achieving the desired weld dimensions.
