X80管线钢焊接材料的选择及其应用
|
摘要
综述了X80管线钢焊接材料的选用原则及工程应用。结果表明,该钢焊接材料的选用可以遵循"组织类型匹配"原则,即尽可能使焊缝的组织接近母材的组织,保证接头获得最佳的力学性能和焊接性。该钢焊接材料的种类有两大类(电焊条和焊丝),5种组合焊接工艺各具特色。STT和RMD工艺是先进的低氢根部焊道技术。自保护药芯焊丝焊缝的低温韧性稳定性尚需严格控制。不同管径和壁厚的X80钢管分别采用匹配的焊接材料和合理的工艺,均在不同的工程中获得成功应用。优质、高效、自动化是工程施工追求的主要目标和方向。
The selection principle and engineering application of X80 pipeline steel welding consumables were reviewed.The results show that the selection of welding consumables can follow the principle of " microstructure type matching ",that is,to make the microstructure of the weld close to that of the base metal as far as possible,to ensure the best mechanical properties and weldability of the joint.There are two types of steel welding consumables(covered electrodes and welding wires),and the five combined welding processes have their own characteristics.The STT and RMD processes are advanced low hydrogen root welding techniques; the low temperature toughness stability of self-shielded flux cored wire welds needs to be strictly controlled.X80 steel pipes with different diameters and wall thicknesses have been successfully applied in different engineering by using matched welding consumables and reasonable processes.High quality,high efficiency and automation are the main goals and directions pursued by engineering construction.
