method and device for connecting pipes of steel through the log gets rid of orbital welding on hybrid technology

摘要

the invention relates to a method of connecting ends of pipes made of steel, preferably with a thickness of more than 6 mm, in particularmore than 12 mm and diameter of preferably more than 150 mm by orbital laser electric arc welding for the hybrid technology, the ends of which are connected is alone or a few layers of seama tool head for laser and electric arc welding in the welding pass through one still assigned the swar key around the end of pipe outside the rail ringand u043fu0435u0440u0435u0434u0432u0438u0433u0430u044eu0442 on circumference of the pipe, the invention relates to a device for implementing the method.the head for laser and electric arc welding separately sets off on a circular rail and in the process of welding is independently moved and r u0435u0433u0443u043bu0438u0440u0443u044eu0442u0441u044f on the circumference of the pipe.
