Can diamond impregnated, nickel plated high strength steel wire 0.010 inches (0.25 mm) in diameter and larger be butt welded into loops?

The person making this inquiry has seen this finished product and questioned is it better to butt welded before or after the plating process?

A second question was could equipment be fabricated in house to perform the butt welding?

It is this authors belief never having seen this product, that the plating process is a post welding operation. Butt welding and the generated heat would severely distort physically disfigure the area of the butt weld. Material removal is likely required to resize the butt weld/upset area. Any pre butt weld plate in that area would have been ruined.

Building equipment with the precision to butt weld material 0.010 inches (.25mm) in diameter is no small task. Alignment, movement and power control would be critical and certainly beyond the scope of this blog. It would be a job for a company that specializes in working with smaller products.
