Three types of coil joining Flash Welders are available with Vertical Spacer Bar, with Horizontal Space Bar, and with Integral Shear. A transfer mechanism successively moves the joint to the trimming station and other optional work stations which include an edge punching or notching station and induction post-heating system. The latter minimizes costly strip breakage by tempering the heat-affected zone in alloy steels susceptible to treatment. Welding machines and freestanding flash trimmers can also be furnished as individual units. Automatic welding control systems are available for quickly and accurately resetting all welding parameters when changing strip size or grade.
All units are available with or without integral shearing mechanisms.
Fully automatic designs are now available to meet today's industry requirements. This feature, using ultrasonics, can detect inferior welds without increasing the stop time of the entry end of the line.
