摘要
文章通过斜Y试验和插销试验研究了超超临界汽轮机组用10Cr-Co3-W2-MoNiVNbNB耐热钢的焊接性。结果表明该耐热钢焊前需预热,焊材不同,预热要求也不同。
The weldability of 10Cr-Co3-W2-MoNiVNbNB heat-resistant steel used in ultra-supercritical unit is studied by Y-slit type cracking test and implant test. The result shows that the steel needs preheating before welding, when using different welding consumables, preheating requirements are different.
