摘要
石油钻采专用阀门的使用有耐强腐蚀性要求,制造时需在内壁表层堆焊耐腐蚀材料。此类阀门具有质量大、形状特殊、焊接可达性差,焊接质量要求严格等特点;重点介绍了Fronius热丝TIG焊工艺和ETR全自动堆焊设备在阀门堆焊制造上的应用。
The special valve in the petroleum exploitation requires excellent corrosion resistance, the valve wall must be cladded with the highly corrosion resistant material dating the production of valve. The valve is characterised by heavyweight.special shape, bad welding performance, but demanding excellent welding quality ere. The article mainly introduces the FRONIUS TIG process and ETR automatic cladding equipment which are applied in the production of valve.
