近年来,我们在铝一钢薄板火焰钎焊方面做了一些尝试,从试验结果上看,薄铝板与薄钢板的钎焊还是可行的。现将具体焊接工艺介绍如下。一、焊前准备铝板和钢板的焊接试片规格:板厚1毫米,面积80×180毫米。焊前用砂布或钢丝刷除去表面氧化物,使其出现金属光泽。焊丝也用砂布擦亮,把铝焊粉用水调成糊状,涂刷在焊丝表面,厚度为0.5～1毫米,烘干后即可备用。准备H01—6型焊炬,2号焊嘴; 焊丝用丝311或纯铝导线;采用粉401。
In recent years, we have made some attempts in the flame brazing of aluminum-steel plates. From the experimental results, it is feasible to braze thin aluminum plates with thin steel plates. The specific welding process is as follows. First, welding before the preparation of aluminum and steel welding test piece Specifications: thickness 1 mm, an area of 80 × 180 mm. Before welding with emery cloth or wire brush to remove the surface oxide, making it appear metallic luster. The wire is also polished with emery cloth, the aluminum solder powder water into a paste, brushing the wire surface, the thickness of 0.5 to 1 mm, after drying can be used. Prepare H01-6 torch, No.2 torch, wire 311 or pure aluminum wire, and powder 401.
