Microwelding principle and characteristic

Microwelding principle and characteristic:

The microwelding is between one kind of butt weld energy, the welding time, the work piece contact resistance accuracy control, had achieved the high grade welding one kind of spot group welds the method, its widespread application in domains and so on electronic circuit manufacture, battery manufacture, instrument measuring appliance, automobile astronautics, medical instrument, lamps and lanterns decoration.

Between the metal the contact can have the contact resistance, the resistance size with meets place the between pressure correlation, the resistance welding is uses resistance pyretogenesis Q=cI2Rt (the Q- heat energy, I- the electric current t- time), and through mechanical technology, electronic technology and so on synthesis utilization accuracy control I, parameters and so on R, t, thus the accuracy control contact point produces the quantity of heat melts the metal, realizes the non-welding materials welding.

The resistance welding does not need to consume the material, does not need the welding rod, the welding wire nucleus to weld the medicine, the welding process is extremely rapid, the thermal centralism, does not have the mist and dust, the non-light pollution, the working voltage lowly (several volts), is one kind of security, economical, highly effective, reliable, controllable, the non-pollution environmental protection welding method.

The molecule welding and the convention resistance welding compares, the welding quantity of heat distribution is more centralized, is smaller to the work piece hot influence, the welding process is stabler controllably, therefore is suitable specially for the small primary device, the precision instrument which welds with difficulty, as well as requests the harsher electronic device to the hot influence.
