近来很多工厂采用苏联先进快速焊接法,而且获得了很大成绩;但是在学习中普遍地存在两个问题: (1)焊接强度问题。 (2)焊条来源问题。为了解决这二个问题,我们进行了一系列较有系统的试验(试验根据见注一),焊接方法是采用了一般使用最广的两种快速焊接法——多条法(束状焊条法)与深熔法(超短弧法)。现在将结果分述如下: 一多条焊接法 (甲)焊接条件 (1)焊件——取两块120×180×10的软钢板(含碳量约0.16％),钢板一边为60°的斜边, Recently, many factories have adopted the advanced fast welding method of the Soviet Union and have achieved great results. However, there are generally two problems in learning: (1) welding strength. (2) electrode source problem. In order to solve both of these problems, we conducted a series of more systematic tests (see note 1 for the test). The welding method uses two of the most commonly used fast welding methods - the multi-beam method ) And deep melting method (ultra-short arc method). The results will now be described as follows: A number of welding method (A) Welding conditions (1) Weldments - Take two 120 × 180 × 10 mild steel (about 0.16% carbon content), the side of the plate is 60 ° hypotenuse,
