WELD ENDING PROCESS AND SYSTEM

摘要

An electric arc welding system and method includes providing a welding apparatus having at least a welding power supply, a wire feeder configured to supply a welding wire, a welding gun having an opening from which the welding wire extends, and a welding controller. The controller can initiate a weld ending process, which senses any contact between the welding wire and a workpiece. In response to any such contact, the controller executes a wire material transfer routine to transfer molten material of the welding wire from the welding wire to the workpiece. This routine can be repeated until the wire feeder stops advancing the welding wire towards the workpiece during the weld ending process.

1. A method of electric arc welding using an electric arc welder, comprising:
providing a welding apparatus having at least a welding power supply, a wire feeder configured to supply a welding wire, and a welding gun having an opening from which the welding wire extends; initiating a weld ending process; sensing contact between the welding wire and a workpiece; and executing a wire material transfer routine to transfer molten material of the welding wire from the welding wire to the workpiece; wherein the wire material transfer routine is repeated until the wire feeder stops advancing the welding wire towards the workpiece during the weld ending process.
