Methods for resistance cladding and welding on hot crack susceptible materials

摘要

Electrical resistance welding with low heat input in conjunction with applied forces effecting compressive forces in the weld are utilized to weld materials sensitive to hot cracking. An electrode coupled with a force applicator performs a low heat input resistance-type weld with triaxial compressive forces introduced in the weld to prevent or inhibit the formation of tensile induced cracks in the weld. This enables subsequent fusion welding overlying the initial weld without risk of hot cracking in the final weld.
