The article deals with the problem of connecting pipelines in the oil and gas industry. To improve the quality of welds on the oil pipeline, the article proposes an alternative method of welding and venting the beam into the atmosphere. This method includes a mobile installation for electron beam welding, in which, in manual mode, it is possible to adjust the seam speed, penetration depth, change the trajectory of the weld and the position of the installation relative to the pipe axis. Guns with a plasma cathode, which allow welding products in the atmosphere, are considered. The power of the generators is also calculated, and the generators are selected corresponding to the put forward requirements. In the course of the work, the authors are designing an electron beam welding unit, which in the future is planned to be developed as a mobile one. The mobile installation includes: a generator directing the belt to the pipe, a horizontal displacement motor, a welding positioner, an electron gun with a plasma cathode.
