仿苏MP-200型凸焊机接触焊在近代工业中占有极重要的地位,特別是在汽車、車輛、飞机制造工业和无綫电工程工业中更获得了广泛的应用。接触焊中有了70％了左右是点焊,但点焊也有某些缺点,例如需要焊接許多焊点,而这些焊点的位置又很相近,則焊接时往往会有分流現象产生,从而影响焊点質量。在这种情况下,就可以采用凸焊的方法。凸焊系將二焊件之一先冲成凹凸形,然后放在电极間进行焊接,使电流集中于較小的面积內。因此凸焊具有高的生产率,并且能得到良好的焊接質量,特别适宜于大量及連續的生产。
Imitation Su MP-200 convex welding machine contact welding in modern industry occupies a very important position, especially in the automotive, automotive, aircraft manufacturing industry and radio engineering industry has also been widely used. About 70% of the contact welding is spot welding, but spot welding also has some disadvantages, such as the need to weld a lot of welding spots, and the location of these welding spots are very similar, the shunt phenomenon often occurs during welding, thus affecting Solder joint quality. In this case, you can use projection welding method. Projection welding will be one of the two welding parts first punch convex shape, and then placed between the electrodes for welding, the current concentrated in a smaller area. Therefore, the projection welding with high productivity, and can get a good welding quality, especially suitable for mass and continuous production.
