Abstract
Some features of development and design of mechanisms of pulsed feed of electrode wire are described. Serious problems are considered, arising at high accelerations in the pulse and at variable feed rates, which consist in the need to reproduce the pulse parameters, set by the electrode wire at its interaction with the feed rollers, lowering the level of mechanism vibrations, affecting the mechanical reliability of the mechanism and the conditions of conducting the welding process. Methods to improve the operating conditions of pulsed feed mechanism are demonstrated.
Keywords: arc weld mg, mechanized equipment, feed mechanism, electrode wire, pulse
