Abstract

A conductive heat resistance deformation welding method for joining work pieces (100, 200) in a work assembly (1000). At least one cover sheet (300, 400), having a higher melting temperature and electrical resistance greater than either work pieces (100, 200) is applied. Passing an electrical current between a primary (500) and a secondary electrode (600) through the cover sheet (300, 400) causes the cover sheet n(300, 400) temperature to exceed the melting point of the work pieces (100, 200). Further heating and moving at least a portion of the work assembly (1000) sufficient to ensure physical contact between the work pieces (100,200) creates a weld pool including a portion of both work pieces (100,200). Solidification creates a weld joining the work pieces (100, 200).
