CO_2气体保护焊是一种高效、节能的焊接方法。它具有效率高、成本低、变形小、无渣、明弧、能全位置焊接、易于实现自动化等优点,所以在生产中得到日益广泛的应用。下面列举一些焊接实例: 1、细丝CO_2薄板焊接某厂的汽车骨架、蒙皮全部为薄板冲压成型的焊接构件(板材为A_3钢、08钢,板厚1～1.5mm)。生产中先分六大片分别组焊,再进行车身总装焊。这种情况,CO_2气体保护焊与手工电弧焊比较提高工效3倍以上。焊接规范如下:
CO_2 gas shielded welding is an efficient and energy-saving welding method. It has the advantages of high efficiency, low cost, small deformation, no slag, bright arc, full position welding, easy to realize automation, so it has been widely used in production. Here are some examples of welding: 1, thin wire CO_2 sheet welding a factory automobile skeleton, skin all the sheet metal forming the welded parts (plate A_3 steel, 08 steel, thickness 1 ~ 1.5mm). Production was divided into six major pieces of welding, and then the body assembly welding. In this case, CO 2 gas shielded arc welding and manual arc welding improve work efficiency more than 3 times. Welding specifications are as follows:
