Resistance Welding Program Functionsgreenspun.com : LUSENET : Resistance Welding : One Thread
Could you please explain the differences between the functions of PREHEAT; WELD; TEMPER; and QUENCH. Is there actually a difference between these functions or are they just a descriptive tag for understanding the program?

Hi Mike- These are all terms associated with older technology AC welders: PREHEAT - Raises the temp of workpiece which seats the part and stabilizes the workpiece before WELD. WELD - Does the bulk of the heating, turns solid metal to plastic/liquid state. QUENCH/TEMPER - Controls grain refinement in refractory metals. Heat treated (annealed) parts can often be brittle if this is not used.
Hope this helps! Kurt Tolliver kurt(@)unitekmiyachi.com
