Abstract
The paper presents some developments made lately by the E.O. Paton Electric Welding Institute, such as hybrid welding methods, activation of processes occurring in the weld pool under the effect of minor additions of chemicals, electric arc welding using an embedded electrode, machines for flash butt and electron beam welding, new filler alloys and fluxes for brazing, and new structural materials. It is noted that structures, constructions and equipment that approach their critical age have substantially increased in number. In this connection, the pressing problem is reliable estimation of residual life of structures using non-destructive testing and technical diagnostics methods. Technology and instruments for welding of live tissues are considered.
Keywords: welded structures, new welding processes, hybrid welding, activation, flash butt welding, electron beam welding and remelting, brazing, titanium, welded structure, residual life, technical diagnostics, acoustic emission, shearogra-phy, welding of live tissues
