Question

tacking before welding can help reduce distortion.

true
false

Explanation:

Analyze the purpose of tack welding

Tack welds are temporary, short welds used to hold metal parts in the correct alignment and joint spacing prior to final welding.

Evaluate the effect on distortion

By mechanically securing the workpieces in place, tack welds resist the thermal expansion and contraction forces generated during the final welding process, thereby helping to minimize warping, shrinkage, and distortion.

Answer:

• True (Correct answer)
• False
