Enameled wire welding machine is a hot pressure welding technology

and it is mainly used to weld the products like stator and steering gear etc. It is a welding method that can heat the terminal and wire with insulation layer

then pressure welding them together

making them connected and conduct electricity. With the help of the internal engineering defect in the production site

and through the analysis of the welding machine’s theory

optimize the welding proposals based on the four stages of original prepressing

welding

pressure maintaining and ceasing

adding the preheating stage into it. Meanwhile

compare it with the benchmark’s level

analyze and determine the main control parameters during the welding process. The optimal control parameters are determined by carrying out the DOE test. Verification in small batch production

implementation of control methods

and ultimately reduce the internal engineering badness rate from 1.29% to 0

achieving the real zero defect.
