化油器常因滑扣和锁孔裂纹而报废。经多次试验,可用气焊修复,方法如下: 1.规范用上海卫星牌微型焊枪,50号焊嘴;施焊火焰接近还原焰。焊条用报废的化油器自制,不需加任何焊药。 2.焊前准备将施焊处洗净,将螺孔中间锯掉一半,裂纹处不需开坡口。除施焊处外,其余工作表面糊上泥巴(耐火土或一般上都可以,但施焊时要求泥巴不能崩开脱落),目的在于防止变形及烧坏工件。 3.施焊工艺 (1)施焊时一定把被焊表面放平。 (2)用中性焰烧化,用直径2
Carburets are often scrapped due to slippage and keyhole cracks. After many tests, available gas welding repair, the method is as follows: 1. Specification Shanghai Satellite micro-welding torch, No. 50 nozzle; welding flame close to the reduction flame. Electrode homemade scrap with a carburetor, without any welding flux. 2. Preparation of welding before welding will be cleaned, the middle of the screw sawed off half of cracks do not need to open the groove. In addition to the welding place, the rest of the work surface paste mud (fire-resistant soil or generally can be, but the welding requires mud can not collapse open off), the purpose is to prevent deformation and burn the workpiece. 3 welding process (1) welding welding surface must be flat. (2) with a neutral flame burned, with a diameter of 2
