点焊是利用焊点(即核心)使焊件达到永久连接的一种焊接方法。它的特点是:加热速度高,并且集中;核心形成过程快,生产效率高;容易实现机械化及自动化。因此在车辆、飞机和电器工业中得到了广泛应用。 在摩托车的焊接结构中,由于钣金冲压件多系低碳钢薄壁结构零件,平板件少,各种圆弧弯曲面零件多,形状较为复杂,因此,点焊就成为摩托车生产中的主要焊接方法。
Spot welding is the use of solder joints (ie, core) to make the weldment to achieve a permanent connection of a welding method. Its features are: high heating speed and concentration; core formation process, high production efficiency; easy to mechanization and automation. Therefore, it has been widely used in the fields of vehicles, aircraft and electrical appliances. In the motorcycle welding structure, sheet metal stamping parts and more low-carbon steel thin-walled structural parts, flat parts less curved parts of a variety of arc shape is more complex, therefore, spot welding has become a motorcycle production The main method of welding.
