摘要
针对Q370R/S31603爆炸焊复合板制4000 m^(3)厚壁球罐的焊接工艺进行深入研究,采用非对称X形坡口,通过E5515-N2焊接基层、E309LMo焊接过渡层及E316L-16焊接覆层的工艺下,经过(590±15℃)×6 h焊后热处理,基层焊接接头的力学性能满足要求,覆层焊缝金属的抗硫化物应力腐蚀试验(E法)、晶间腐蚀试验(C法、E法)均合格,耐蚀性能良好。制定的焊接工艺能够满足工程需要。
Aiming at E5515-N2 electrode welding base layer,E309LMo electrode welding transition layer and E316L-16 electrode welding cladding layer,after 590±15℃×6 h post weld heat treatment,the mechanical properties of the base welded joint still meet the requirements;The results of sulfide stress corrosion test(E-method)and intergranular corrosion test(C-method and E-method)of cladding weld metal are qualified,and the corrosion resistance is good.The welding pro‐cess can meet the engineering needs.
