这种方法比手工堆焊的生产率要高2.5～3倍。圖示是用T-590型硬質合金塗料及变断面板極堆焊的鼓風机叶片。堆焊的方法非常簡單而有效。按照堆焊表面的形状及尺寸,准备好敷有T-590型塗料的板極,干燥及焙燒以后即可使用。在堆焊表面上撒一層-45焊蘗,放上敷有塗料的板極,再在板極上面复盖一層較厚的同样焊药。为了防止撓曲,在上面压一塊較重的鋼板或铁板。在板極带有尖角的一端,通过專門鋪置碾碎的能导 This method than manual welding productivity 2.5 to 3 times higher. Pictured is the use of T-590 carbide coating and the transformer plate off the surfacing blower blades. Surfacing method is very simple and effective. In accordance with the shape and size of the surfacing surface, prepare a plate coated with T-590 coating, which can be used after drying and baking. Spread a layer of solder on the surfacing -45 tiller, put the coated board pole, and then covered in a thick layer above the same flux. To prevent flexing, press a heavy steel or iron plate over it. On the plate with the sharp end, through the laying of crushed can guide
