通过对09MnCuPTi等四种耐候钢和结502WCu等六种耐候钢焊条、焊丝的各种试验和分析,表明国产耐候钢和耐候钢焊条、焊丝具有良好的焊接性和耐腐蚀性。装车实践证明,应用国产耐候钢及其焊条、焊丝制造铁道年辆,无需改变现有生产条件和采用特殊的焊接工艺措施。此外,经火焰加工工艺试验,认为耐候钢热压成型温度为900~1000℃。
By testing and analyzing the four kinds of weathering steels such as 09MnCuPTi and the weathering steel of the five knot 502WCu, it shows that the domestic weathering and weathering steel electrodes and welding wires have good weldability and corrosion resistance. Loading practice has proved that the application of domestic weathering steel and its electrodes, wire manufacturing years of the railway, without changing the existing production conditions and the use of special welding process. In addition, the flame processing technology test, that weathering steel hot forming temperature of 900 ~ 1000 ℃.
