Features of designing mechanisms of pulsed feed of welding wire in welding equipment

摘要

Some features in development and designing of a mechanism of pulsed wire feed are considered. Serious problems are enumerated, arising at high accelerations in the pulse and 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 and means to improve the operating conditions of the pulsed feed mechanisms are demonstrated.
