一、焊接原理电阻焊是采用交流电,利用被焊接材料本身去搭接时的接触电阻产生热量来将材料熔接的一种焊接技术,如图1所示。当罐身在上下焊轮之间通过时,旋转的焊轮在对材料加压的同时,上下焊轮之间的低压大 First, the welding principle Resistance welding is the use of AC, the use of the welding material itself is overlap when the contact resistance heat generated to weld the material welding technology, as shown in Figure 1. When the can body passes between the upper and lower welding wheels, the rotating welding wheel pressurizes the material while the low pressure between the upper and lower welding wheels is large
