In a flash butt welder for joining strip ends, the improvement for improving the quality of flash butt welds made in specialty grade steels, such as high strength low alloy, as well as for considerably reducing the upset current requirement, by applying a protective atmosphere of combustible gas, such as propane, natural gas, or hydrogen during the flash butt welding process. Welds free from any detectable defects can be made with lower upset current densities thus extending the equipment welding capacity.

Flash butt welder for joining flat strip ends

A welding machine auxiliary transfer clamp for pushing the end of a coil against a spacer bar and including a pair of clamping elements, each including a cylindrical ram operated by fluid cylinder, there being a ball connection intermediate each fluid cylinder and its respective ram to enable the upper and lower rams to pivot freely about their longitudinal axis so as to prevent occurrence of a gap otherwise formed by lateral tilting of the coil, whose end is to be welded.

Welding machine auxiliary transfer clamp

A spacer plate construction for use in selective spacing between the head end and tail end of strips to be welded end-to-end by a welding machine. Sensors in the form of spring biased pivotal (or otherwise moveable) elements are mounted in longitudinally spaced cavities in the spacer plate to assure that the strip ends are held flush against the spacer plate before clamping for subsequent flash or butt welding. It is only when the sensor elements are moved inwardly to the sides of the spacer plate sufficiently to actuate a proximity switch mounted within the sensor plate that a circuit for initiating clamping of the head end and tail end of the strips can be initiated for subsequent welding.
