热平衡
During resistance welding, part of the heat generated is lost to the surroundings by conduction (heat transfer through solids), convection (heat lost from exposed surfaces by air-cooling), and radiation (does not require a medium). Heat balance is a function of part material and geometry, electrode material and geometry, polarity, and the weld schedule.
The goal of good resistance welding is to focus the heat generated close to the weld interface at the spot where the weld is desired. For more information, read our blog 热平衡:电阻焊成功的关键。
