Force for spot welding
WebFeb 8, 2024 · Spot welding is suitable in many situations, although there are quite certain restrictions. It can fabricate only confined joins, which are generally weak. The spot weld strength is dependent on the electrode force, welding current, welding time, and the temperature that has been used. WebMay 1, 2014 · For the most part, the resistance-projection-welding (RPW) process is very similar to the spot-welding process. During spot welding, the size of the contact surface of the electrode cap determines current …

Websignificantly. The three main parameters that govern spot weld quality are current, time and force. Proper control of these parameters will generate the required heat for melting the metal and development of spot weld nugget. Increase in spot weld nugget diameter has been shown to increase spot weld strength [1]. WebThe solution to welding copper is to use an electrode made of an alloy with a high electrical resistance and a melting temperature far in excess of the melting point of copper (much greater than 1080°C). Electrode materials …
