In case of solid phase welding, it is necesary to heat the joining materials at last above recrystalization temperature of either one. And in the joining process, the pressure and surface tension of the materials are important factor to accelerate the joining. For these reasons, the materials which have high melting point could be solid-phase-welded during 30-60 seconds at a temperature little higher than their recrystalization temperature by use of the powder as medium. By the joining method mentioned above, tungsten, tungsten carbide, quartz and etc. were solid-phase-welded with each other by use of powder of appropriate materials as medium, and its strength was close to that of the materials, when this joining method was applied to common metals, the results were obtained as indicated in the following examples, the joining strength, when Cr-steel was welded by use of Co-powder as medium, was about 65kg/mm^2 and that, when Cr-steel welded by Ni-powder, was about 50kg/mm^2.
