Abstract

Welding appts. comprising a fine wire electrically heated to be moved slowly between a butt joint between two fusible pieces of material to produce a progressive weld by local melting. The wire is mounted either in tension across a yoke between the jaws of which the workpieces can be passed, or as a loop on the end of a fixed or portable holder. Provides simple, portable or semiportable equipment for fabricating assemblies of thermoplastic components using continuous or spot welds. The appts. uses little energy and does not produce a prominent weld lip.
