| titleOfInvention | Projection welding quality discrimination method |
| abstract | To provide a method capable of automatically determining the quality of welding quality in projection welding. In a quality determination method of projection welding, a welding material 2 having a protrusion and a material 2 to be welded having no protrusion are pressurized and energized by a pair of electrodes 1a and 1b to form a nugget. Before the test, test welding for forming an appropriate nugget is performed, and the temporal change of the instantaneous power value Pd during the test welding is A / D converted at predetermined intervals and stored as a data string. The stored data string Based on the above, the power reference value generation circuit PS generates a power reference pattern, and when the instantaneous power value Pd during the main welding changes within a predetermined range Ps ± ΔPs from the power reference pattern, the welding quality is good. Determine. [Selection] Figure 1 |
