躺板极电渣堆焊是对大面积的水平表面进行堆焊的一种有效方法。它的优点是工艺简单,操作方便,易于掌握,不需复杂的设备,生产率高。用容量不大的焊机,就可以一次行程堆焊出宽度达100毫米的焊道。目前,堆焊在我国已经受到广泛的重视,特别是用堆焊法来制造各种耐磨、耐腐蚀等合金钢的双金属零件,对节省贵重的合金钢材具有重大的经济意义。关于采用躺置的大截面板状焊条在熔剂层下进行电弧焊的方法,早在1948年苏联就已有人提出。在
Electrodeposition surfacing electrode is a large area of the horizontal surface of an effective method of surfacing. Its advantages are simple process, easy operation, easy to grasp, no complicated equipment, high productivity. With a small capacity of the welder, you can surfacing up to a width of 100 mm weld bead. At present, surfacing welding in our country has received widespread attention, especially the use of surfacing to manufacture all kinds of wear-resistant, corrosion-resistant alloy steel bimetal parts, to save valuable alloy steel has great economic significance. The method of arc welding with a large cross-sectional plate electrode lying under the flux layer has been proposed by the Soviet Union as early as 1948. in
