Abstract: Method for welding piped (2, 3) to each other, in which the outer side of the one pipe is engaged tightly with the help of first clamping means and the outer side of the other pipe is engaged tightly with the help of second clamping means in which the first and second clamping means are kept in the line and with their ends close to or against each other by means of a rigid frame on which both clamping means are arranged, after which welding means are operated in order to make a welding seam from the outside for connecting both pipes, after which the frame with the first and the second clamping means and with the welding means is moved along and over the other pipe to the other end of the other pipe for repeating the aforementioned steps for welding the other pipe and a next pipe.
