车圈对焊是利用车圈的内部电阻和接触电阻所产生的电阻热,在高电流密度的作用下,使金属迅速熔化,蒸发,爆破使接头附近形成一定宽度的高温区后,在撞击式顶锻压力作用下,将车圈焊为一体的一种焊接方法。由于这种方法,使车圈接头加热区窄,端面加热均匀,接头质量好,生产效率高,因此,在自行车生产中得到广泛应用。为获得优质车圈接头,除了根据车圈的
Rim welding is the use of the car’s internal resistance and contact resistance generated by the resistance heat, the role of high current density, the rapid melting of metal, evaporation, blasting to form a certain width near the joint after the high temperature zone, the impact type Top forging pressure under the action of the rim welding as a welding method. Due to this method, the heating zone of the rim joint is narrow, the end surface is heated evenly, the quality of the joint is good and the production efficiency is high. Therefore, it is widely used in bicycle production. In order to obtain high-quality rivet connector, except according to the rims
