ABSTRACT:
The disclosure relates to a method and a device for butt-welding rotational cylindrical metallic rods without filler metal and without forming a rim or deformation in the welded area. The method consists of bringing the two ends coaxially to be welded into contact proximity without compression and applying welding power while simultaneously rotating the two rods in relation to the welding heat source around their common rotational axis to an extent of more than one complete revolution.
