... was due to a defective resistance butt-weld which had been made when the wire was in process of drawing, such welds being essential in order to obtain continuous long lengths of wire. It was apparent that fusion had not occurred over the whole of the cross-section, with the result that the stresses...

... at the fracture itself it was completely spheroidized. Therefore the wire was locally annealed at this point. It was likely that the wire cracked at this point during the last drawing and then broke during twisting due to its lower strength in the weakened cross section after prior deformation. Annealing...

..., or by terminating welding on runoff tabs that are cut away later. If crater cracks are found, they should be chipped out and the area rewelded, because it is very difficult to melt out a crater crack. Hat cracks (No. 9, Fig. 3 ) derive their name from the shape of the weld cross section with which...
