In plasma arc welding (PAW), what distinguishes the 'keyhole' technique from conventional fusion welding?
Answer: B. A high-velocity plasma jet penetrates completely through the base metal, creating a hole that is progressively filled as the torch advances
In keyhole PAW, the constricted plasma arc fully penetrates the joint, and surface tension holds the molten metal as the keyhole moves forward, enabling full-penetration single-pass welds.
Which welding process is best for welding aluminum?
Answer: B. TIG Welding
TIG welding is generally considered the best process for welding aluminum due to its ability to produce very clean and high-quality welds. The use of AC current in TIG welding helps to break up the tenacious aluminum oxide layer, which is crucial for achieving good penetration and a strong, defect-free weld. This precision is vital for aluminum's properties.
A welder notices that a long steel beam is bowing upward after welding along its bottom flange. Which corrective measure is most appropriate BEFORE welding?
Answer: A. Pre-camber the beam opposite to the expected distortion direction
Pre-cambering positions the workpiece opposite to anticipated distortion so that after welding, the part returns to the desired geometry.
What does the arrow in a welding symbol typically indicate in welding symbols & blueprint reading?
Answer: A. Weld location
In a welding symbol, the arrow points directly to the joint or area where the weld is to be made. It indicates the 'arrow side' of the joint, which is crucial for distinguishing between welds on one side versus the other or both sides of a joint. This ensures the welder places the weld in the correct position as specified by the design.
