手工电渣焊是电渣焊中最簡便的一种方法,不需要复杂的設备与装置,焊接生产率高,焊接質量好。手工电渣焊是苏联首先創造并已用于鋼筋焊接工作上。1958年苏联巴頓电焊研究所进一步研究了在鑄铁补焊方面应用的可能性。我們的工作是在苏联巴頓电焊研究所試驗的初步結果的基础上結合我国情况进行的。用手工电渣焊焊朴鑄铁件缺陷时,先将缺陷处清理干净,在其中放入石墨棒并短路,再放入少量AH-348A焊藥,拉起石墨棒引弧,利用电弧将焊藥熔化(如圖1)。
Electroslag welding is the most simple method of electroslag welding, without complicated equipment and devices, high welding productivity, good welding quality. Electroslag welding manual was first created by the Soviet Union and has been used for steel welding work. 1958 Soviet Barton Welding Institute to further study the possibility of welding in the cast iron. Our work was carried out on the basis of the preliminary results of tests conducted by the Barton Institute of Welding at the Soviet Union in light of our country’s situation. Electro-slag by hand welding the cast iron pieces defects, the first defect clean-up, in which graphite rods and short circuit, then add a small amount of AH-348A flux, pull the graphite rod arc, the use of arc welding Medicine melts (Figure 1).
