焊接技术是许多现代工业部门的基本生产手段,如汽车、锅炉、家用电器、飞机制造等工业部门。可以大致的说,没有现代焊接技术的迅速发展,就不会有现代工业和科学技术的发展。我们知道,电阻焊是工业中应用较为普遍的方法之一,电阻焊是由电阻焊机来实现的,在五十年代或六十年代,电阻焊机基本上是以辉光闸流管作为电力开关的,目前大都更新以可控硅元件作为电力开关,就其控制方式来讲,它们都是属于开环控制的系统,焊机电路
Welding technology is the basic means of production in many modern industrial sectors, such as the automotive, boilers, household appliances, aircraft manufacturing and other industrial sectors. It can be roughly said that without the rapid development of modern welding technology, there will be no development of modern industry and science and technology. We know that resistance welding is one of the more popular methods used in industry. Resistance welding is accomplished by resistance welding machines. In the 1950s and ’60s, resistance welding machines were basically powered by a glow thyristor Switch, most of the current update to SCR components as a power switch, in terms of its control, they are all open-loop control system, the welding circuit
