What is the no electrode welding process?


Like flash welding, welding principle and is very simple, it is mainly used for reinforcement, and docking of small cross section rod bar material, is through the two high-power electrodes (usually copper pad) respectively two workpiece clamping, electricity, then make two workpiece contact, strong current through the workpiece, make it produce a lot of heat, welding can be controlled by a handle of the contact and broken time, contact, artifacts will be melt, react with oxygen, dazzle beautiful, welder can spark according to determine heating temperature, is part of welding materials melt, the pressure and then reuse it.The performance of the joint is very good, the strength can meet the requirements.
