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.

Method for welding pipes to each other, in which the outer side of the one pipe is engaged tightly with the help of first clamping means and the out 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 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, while being supported on said other pipe, for repeating the aforementioned steps for welding the other pipe and a next pipe.
Device for welding pipes to each other, comprising a rigid frame having first clamping members for tightly engaging the outer side of the one pipe and having second clamping means for tightly engaging the outer side of the other pipe, having its end at welding distance from and in line with the end of the one pipe, and having means for moving the frame along and over the pipes, while being supported on said pipes, after making the welded joint between the pipes.
