Braze Pressure Welding (BPW) with high frequency induction heating is a newly developed pressure welding technique using brazing filler as interlayer metals for welding the general steel pipes for pipe arrangement in buildings. In this report, stainless steel pipes were joined by BPW with some kinds of interlayer metals, and the joint of the pipes made by BPW were evaluated by microscopy, element profiles and tensile strength of the joints in order to determine the suitable interlayer metal for BPW of stainless steel pipes. As the result of this research, the BPW joint using BNi-2 as interlayer metal was stronger with less melting of base metal than that of the BNi-5. A newly developed Fe-base interlayer metal was also suitable for BPW of stainless steel pipes.
