ABSTRACT:
Disclosed herein is a portable frictional welding device whereby union of a metallic part with a given structure is accomplished by fastening said metallic part to the rotary shaft of the device supported slidably in the axial direction thereof, operating the rotary shaft so as to rotate the metallic part and at the same time pressing it against the structure and, when the point therebetween has assumed a state of fusion, stopping the rotation of the rotary shaft and simultaneously increasing the thrust being applied to said structure.
