Abstract:
Apparatus for determining a quality of a weld produced by a welding device, comprising:a sensor operatively associated with the welding device, said sensor being responsive to at least one welding process parameter during a welding process, said sensor producing a welding process parameter signal relating to the at least one welding process parameter;a computer connected to said sensor, said computer being responsive to the welding process parameter signal produced by said sensor;a user interface operatively associated with said computer, said user interface allowing a user to select a desired welding process;a constant voltage algorithm operatively associated with said computer;a short duration weld algorithm operatively associated with said computer; anda pulsed current analysis module operatively associated with said computer, said computer processing the welding process parameter signal produced by said sensor in accordance with one of said constant voltage algorithm, said short duration weld algorithm, and said pulsed current analysis module depending on the desired welding process selected by the user, said computer producing output data indicative of the quality of the weld.
