Polishing method for spot welding electrode of seat
Technical Field
The invention relates to a method for grinding a spot welding electrode of a seat, and belongs to the technical field of automobile welding processing.
Background
Because the seat spot welding is in welding process, along with the use of electrode, the oxide layer on electrode surface can be thicker and thicker, reduces the electric conductivity of electrode at last to lead to the welding failure. At this time, this problem can be solved by replacing the electrode or performing maintenance on the electrode. Direct replacement undoubtedly increases production costs, and since the electrodes are not scrapped, the replacement also results in waste due to insufficient utilization of materials. In maintenance, an oxide layer on the surface of an electrode needs to be removed to ensure good weldability of the electrode, and a simple and effective processing method is not available in the prior art, so that the electrode is manually repaired and polished by the company, flatness cannot be mastered in the polishing mode, trouble and labor are wasted, the polishing mode is insufficient in flatness, stress is uneven during welding, the performance of the side with light stress is reduced, even accidents such as direct falling off occur, and in order to ensure production quality, a method with high polishing efficiency and good polishing flatness needs to be developed.
