我厂生产的焊接产品中,手工电弧焊占很大一部分,因此由于飞溅使工件表面(焊缝附近)很脏且影响涂漆。我厂曾较长时期采用喷砂方法清除飞溅;但这一办法既浪费工时又不能彻底清除。如众所知,手工电弧焊之飞溅是不可避免的,在当前条件下,即使在焊条的制造上下工夫和采用适当的焊接规范,亦只能起飞溅金属减少之作用,仍不能消灭。所以探讨适宜的方法使飞溅金属易于清除,减少喷砂这一工序,以节省人力、节约 I produced a lot of welding products, manual arc welding accounted for a large part of the surface of the workpiece due to the splash (near the weld) is dirty and affect the paint. I plant a longer period of time using sandblasting method to remove splashes; but this approach is not only a waste of time and can not be completely removed. As we all know, manual arc welding spatter is inevitable. Under the current conditions, even if the welding rod is made and the proper welding specifications are adopted, it can only take off and splash the metal and can not be eliminated. So to explore the appropriate method to make the splash metal easy to remove, reduce the blasting process to save manpower, saving
