In electrical resistance welding, both
heat and pressure are used to effect coalescence. The pressure necessary to
effect the weld varies from :
50-100kgf/cm2
100-200kgf/cm2
250-500kgf/cm2
500-850kgf/cm2
250-500kgf/cm2
In electrical resistance welding, both heat and pressure are usedto effect coalescence. The pressure necessary to effect the weld varies from 250-500kgf/cm2.
Hence, the correct option is (C).
