发电机爪极与风扇点焊的探索

论述了电视风扇与爪极焊接，探讨了1 mm低碳钢板与20mm以上低碳钢（铸造钢）板点焊的机理．提出了薄板与厚板点焊时，电场与温度场只决定于薄板上使用的电极工作型面．指出了物体的热情性对焊接的影响。

In this paper, the welding of motor fans and pawlpoles, and the mechanism of spot welding of mildsteel sheet of lmm in thickness and that of more than 20mm in thickness (cast steel) It has been put forwardthat the electric and temperature fields depend only on the shape and area of the electrode applied to the thinner sheet during welding. How the thermal inertia affects welding has also been discussed.
