Abstract
A method is provided for joining the ends of steel pipes having male and female ends. The pipe is inserted with the male end into the pipe with the female end and a circular seam is welded, which is disposed at the inside of the female pipe for solidly connecting the pipe with the male end to the pipe with the female end. The male end is preferably provided with a ball section and the female end correspondingly with a ball shaped socket for allowing the pipe to be angled at the connection points. The invention provides the advantage that in automatic welding no large head holes have to be dug out.
