提高手工电弧焊接劳动生产率的主要方法之一,就是采用大的电流和粗的焊条。在苏联,有些地方已经广泛地采用φ8公厘的焊条进行焊接,有的甚至采用φ10公厘的焊条来焊接。在这种情况下,运用结构简单、性能良好、使用方便的焊条夹钳,便成为很重要的问题。下面介绍的,是苏联一般工厂采用的焊条夹钳。图1是一种φ10公厘焊条夹钳,所有零件都是用普通材料制成的。这种 One of the main ways to improve labor productivity in manual arc welding is to use large current and thick electrodes. In the Soviet Union, some places have been widely used φ8 mm welding rod welding, and some even φ10 mm welding rod to welding. In this case, the use of simple structure, good performance, easy to use electrode clamp, has become a very important issue. Described below are the electrode clamps used in the general factory in the Soviet Union. Figure 1 is a φ10 mm electrode clamp, all parts are made of ordinary materials. This
