Abstract

The effect of external loads and the type of welded joint on the stress-strain state in the seam at the electron beam welding. It is shown that the argon arc welding, which is characterized by multilayer during welding of large thickness and a large residual strain in the welded joint leads to a weakening of the retention of structural elements. In some cases, the technical task conditions on structural elements should not be heated above a certain temperature during welding. This constraint greatly increases the TIG welding, since the imposition of a weld produced in small areas. The efficiency of electron beam welding with respect to TIG. Calculated temperature field and the stress-strain state of welded joint during welding and after.
