Improvement of technical characteristics on orbital argon-ark welding at the expense of arch activation
In work results of research of activation of an arch are resulted at orbital welding of pipelines. It is shown that activation allows to carry out not rotary joints of pipes with thickness of a wall to 6 mm without cutting of edges for one pass, and at welding of more thick-walled pipes provides a t...

Journal of Mechanical Engineering| Резюме: | In work results of research of activation of an arch are resulted at orbital welding of pipelines. It is shown that activation allows to carry out not rotary joints of pipes with thickness of a wall to 6 mm without cutting of edges for one pass, and at welding of more thick-walled pipes provides a thickness of root pass to 5 mm. Arch activation sharply reduces dependence of a welding current on spatial position of a welding bath. It simplifies technics of welding and reduces the price of the equipment for its realisation. |
