Auxiliary wire feeding method for gas protection of melting pole

Abstract

The invention relates to an auxiliary wire feeding method for gas protection of a melting pole, and the method can effectively solve the problem of wire feeding stability when loading welding wires byusing a heavy-weight barrel or disk. The technical scheme for solving the problem is as follows: the method comprises the following steps of: 1) installing a welding wire; 2) pre-adjusting the welding wire cache amount; and 3) adjusting the welding wire cache amount during welding; according to the invention, the load of a wire feeder can be reduced, and the wire feeding stability when loading the welding wire by using the heavy-weight barrel or disk can be improved, and the auxiliary wire feeding device controls the wire feeding speed of an auxiliary wire feeding power device through a PLC controller, so that the welding wire always has a certain margin in a welding wire cache box, and the welding wire is kept in a bending state, which is an innovation of the wire feeding device.

Description

technical field [0001] The invention relates to the field of welding, in particular to an auxiliary wire feeding method for gas protection of a melting pole. Background technique [0002] When using molten electrode gas protection for large-scale weld welding and large-area surfacing welding, the welding time is usually longer, the amount of welding wire is large, and the requirements for the continuity of welding wire feeding are high. Install welding wire to ensure the continuity of welding. The wire feeding resistance of barreled and heavy-weight coiled welding wire is larger than that of standard coiled welding wire, and the load of the wire feeder is large, which is prone to unstable wire feeding, resulting in welding defects, and the wire feeder works for a long time under heavy load , have adverse effects on its working stability and service life. Therefore, an auxiliary wire feeding device that can reduce the load of the wire feeder and improve the stability of wire...
