摘要
采用E11018-G和E12018-G两种不同强度的焊材,对SA517Gr.B高强钢进行焊接工艺试验研究,进行拉伸试验、侧弯试验和冲击弯试验。结果表明,E11018-G和E12018-G焊接材料均能够满足SA517Gr.B钢材的焊接技术要求,采用E11018-G可有效降低接头焊接应力,降低焊缝裂纹敏感性,提高焊缝质量稳定性。
The welding procedure of SA517Gr.B was studied based on the two different welding consumables EI1018-G and E12018-G which has different strength in this paper. Tension test,guided-bend test and notch-toughness test were done,and the results show that both EllO18 and E12018 are meet the welding technical requirements of SA517 Gr.B. Ell018-G can reduce the welding stress and cracking sensibility, and gain steady-quality weld.
