摘要
采用同材质的R307焊条焊接了13CrMo44珠光体耐热钢。通过抗裂性和焊接工艺性试验证明,只要采取焊前预热160℃、焊后后热以及焊后热处理,就能获得良好的焊接接头。
13CrMo44 pearlyte heat resistant steel has been welded with the same matched material of R307 electrode. Through crack resistant testing and weld procedure testing, it has been proved that a good weld joint can be obained with pre-heating at temperature 160℃ amd post-healing at temperature 680℃ treat procedure.
