Strip positioning device
TL;DR: In this paper, a positioning mechanism for a clamp in a strip welding machine having a platform with slide means and means reciprocably supporting the slide means thereon is presented, where a carriage is provided for supporting the clamp and guide means are provided on the platform for supporting a carriage for movement transversely of the sliding means, where at least one contact surface, fixed with respect to the carriage, is provided and is slideably engaged with the contact surface on the slide meant for causing the carriage to reciprocate along the guide means in response to reciprocation of the slide mean.
Patent
Welding method and apparatus
TL;DR: In this article, a method of welding which is particularly advantageous in the resistance butt welding of tubes, rods, and other similar articles is described, which also relates to the manufacture of large flat tubular coils.
Patent
Shear in gap flash welder
TL;DR: A double cut guillotine shear is normally positioned forwardly and alongside the welder at a "stand-by" position, remote from the welding position to avoid splattering from welding sparks.
