摘要
12Cr1Mo VG属于常见的珠光体耐热钢,15Cr Mo属于低合金珠光体耐热钢,这两种异种钢都具有很好的抗氧化性与热强性,但这两种钢在进行焊接时,都容易出现冷裂纹等缺陷。针对这一问题,主要对12Cr1Mo VG与15Cr Mo异种钢的焊接工艺进行了分析,对厚壁管道合理的焊接工艺与热处理工艺进行了优化研究。
12Cr1MoVG belongs to the common pearlitic heat-resistant steel, 15CrMo belongs to low-alloy pearlitic heat-resistant steel, the two kinds of dissimilar steel has a good oxidation resistance and heat resistance, but the two kinds of steel in the welding, Are prone to cold cracks and other defects.In order to solve this problem, the welding process of 12Cr1MoVG and 15CrMo dissimilar steel is analyzed, and the reasonable welding process and heat treatment process of thick-walled pipeline are optimized.
