组合式凸焊电极 Composite projection welding electrode

设计工作表面大于凸点直径的两倍，既保证焊接质量，又可使被焊工件在电极压力下不易变形。电极工作部分与电极座采用分体插入式，便于维护。交流焊机中定位部分选用非铁磁性材料，可减少电流损耗。

The designed work surface shall be two times larger than the diameter of the protruded point . The welding quality will be ensured and deforming of components under electrode pressure will be avoided. The working part of electrode and electrode base is split insertion type for easy maintenance. The poritioning part of AC welding machine is mon-iron magnetism to reducing current waste.
