Red Seal Welder Practice Exam

What potential problem can result from improper amperage settings?

1. Improved weld penetration

2. Increased welding speed

3. Poor quality welds

4. Higher worker productivity

The correct answer is: Poor quality welds

Improper amperage settings can lead to poor quality welds because amperage directly affects the heat input during the welding process. Insufficient amperage may result in incomplete fusion between the base materials, leading to weak joints and possible cracking or insufficient penetration. Conversely, excessive amperage can cause burn-through, excessive spatter, and distortion of the base materials. Both scenarios compromise the integrity of the weld, making it critical to set the appropriate amperage according to the type of material and thickness being welded. In contrast, improved weld penetration, increased welding speed, and higher worker productivity are generally associated with optimal settings rather than improper ones. Therefore, while those factors can positively influence a welding operation, they are not the result of improper amperage settings.
