W Cu低合金耐候钢焊条是一种用来焊接各种耐候钢制造的焊接结构的新型焊条。本系列焊条以Cu和W作为耐候元素。通过盐雾腐蚀、周浸腐蚀、电化腐蚀及大气挂片四种腐蚀试验,表明了这种合金系列焊条较之现行的耐候钢焊条具有更好的耐大气腐蚀能力和抗裂纹能力。经齐齐哈尔车辆制造工厂生产实践证明,不预热焊接铁路车辆时不产生裂纹。
W Cu low alloy weathering steel electrode is a new type of electrode used to weld various welded structures made of weathering steels. This series of electrodes to Cu and W as weathering elements. Through the corrosion test of salt spray, immersion etching, galvanic corrosion and atmospheric coupon, it shows that the alloy electrode has better resistance to atmospheric corrosion and cracking than the current weathering electrode. After Qiqihar vehicle manufacturing plant production practice proved that, without preheating welded rail vehicles without cracking.
