苏联巴顿电焊研究所曾经研究过板厚达50公厘的不开坡口留大间隙的自动埋弧焊接法。1956年底,我厂苏联专家格列明尼柯夫同志建议在生产中推行极厚在30公厘以下不开坡口留大间隙的埋弧自动焊接法;在1957年初,我们开始这项研究试验工作。这种新的焊接工艺,可以不开坡口,因此取消了开坡口的工序,节省了开坡口的材料,也节省了填充金属和电能。重要的是要在试验中求出合适的焊接规范,并观察这种新工艺的特点,如何在生产中加以推广,这就是此项试验工作的目的。
Barton Welding Research Institute of the Soviet Union has been studied plate thickness of 50 mm without leaving a large groove gap automatic submerged arc welding. At the end of 1956, Comrade Mikelnikov, a Soviet expert in our factory, proposed the automatic submerged arc welding with a very thick groove below 30mm without leaving a large gap in the groove. In early 1957, we started the research experiment jobs. This new welding process, can not groove, thus eliminating the process of the groove, saving the groove material, but also saves the filler metal and electric energy. It is important to try to find the right welding specifications and observe the characteristics of the new process and how to promote it in production. This is the purpose of this test.
