TIG焊工艺方法的应用目前工业上的各个部门都在广泛地使用这种工艺方法,它可焊接薄材料,其厚度可薄到0.5mm;也可对较大工件进行精密焊接。可以将十分微小的电弧准确地置于待焊接头上,可将热量控制到使所产生的变形降低到最小程度。对于厚度为0.5~3mm的材料进行对接焊时,一般说来均是材料本身进行焊接,就是说,不用填充金属。然而,如果接头的形式是有间隙的,那末在焊接时就要求焊缝有加强高;或者如果材料本身使焊缝中产生裂纹或气孔时,就必需使用填充金属。填充金属可以以焊丝或焊条的形式加入,其成份与母
The application of TIG welding process method At present all sectors of industry are widely used in this process, it can be welded thin material, the thickness can be as thin as 0.5mm; also can be a large workpiece precision welding. A very small arc can be accurately placed on the weld to be welded, and the heat can be controlled so that the resulting deformation can be minimized. For the thickness of 0.5 ~ 3mm material for butt welding, generally speaking, the material itself is welded, that is, without filling the metal. However, if the joint is in the form of a gap, then the weld is required to be strengthened during welding or it is necessary to use filler metal if the material itself causes cracks or porosity in the weld. Filler metal can be added in the form of wire or rod, its composition and the mother
