Abstract
A method and system to determine optimum operating parameters for the startup phase of a welding-type process based on user-desired operating parameters of the post-startup or welding phase of the welding-type process are disclosed. While applicable to a number of welding-type processes, the method and system are particularly configured to determine an optimum wire feed speed for Gas Metal Arc Welding of aluminum using pulse spray transfer.
Claims30
A welding-type device comprising a controller configured to:
- receive an input value for a welding-type parameter, the welding-type parameter designed to establish an operation of a welding-type process;
- determine an offset value to the input value for the welding-type parameter, the offset value designed to establish an operation of the welding-type process during a startup period of the welding-type process;
- and
- enable user selection between the input value and the offset value for the welding-type parameter for the startup period of the welding-type process.
The welding-type device of claim 13 wherein the controller is further configured to limit user adjustment of the determined offset value to a preferred offset value not less than the input value.
A method of fusing aluminum to a workpiece comprising the steps of:
- receiving an input for a desired weld wire feed speed;
- determining an optimum startup wire feed speed from the desired weld wire feed speed;
- initiating a welding process at the optimum startup wire feed speed for a startup time period;
- and then
- continuing the welding process at the desired weld wire feed speed after expiration of the startup time period.
A controller for a welding-type system configured to:
- determine a first set of operating parameters designed to govern a welding-type process after an initialization period;
- determine a second set of operating parameters designed to govern the welding-type process during the initialization period based on the first set of operating parameters;
- and
- carry out the welding-type process such that the second set of operating parameters governs the welding-type process during the initialization period and the first set of operating parameters governs the welding-type process after the initialization period.
