Answer :
Final answer:
The answer to the question is 'b. Staggered intermittent weld' indicating a welding technique where welds are placed in staggered intervals along the joint to control distortion or meet specific design needs.
Explanation:
In the context of welding symbols, when welds are offset from each other on the symbol, it indicates a staggered intermittent weld.
This type of welding involves a series of welds placed at specified intervals along the joint, but unlike regular intermittent welds where the welds are aligned directly opposite each other, in a staggered pattern, they are offset.
This technique is often used to control distortion, reduce the amount of welding required, or accommodate specific design requirements.
For example, it might be employed in the construction of a metal frame where strength needs to be distributed evenly but full continuous welding is not necessary or cost-effective.
