耐磨合金堆焊焊条研究

Study on Bead Welding Rod of Wear-Resisting Alloy

对高碳W12Mo6V3Cr2合金系统的合金焊条进行试制研究，发现当合理调整焊条化学成分时，能使焊缝金属具有隐晶马氏体、残余奥氏体、碳化物组织，其组织晶粒细化，加之，焊条采用碱性渣系和适当地过渡钒在焊缝金属中的含量，从而大大地提高了焊条的工艺性能和焊缝金属的抗裂性能。

According to the alloy welding rod development and test of higher carbon W12 M06 V3 Cr2 allo system as reasonablly adjusting chemical components of welding rods, it is found that there are hidden crystal martensite + residual austenite + carbonate organizations in welding seam metal and their crystal granules beconme refining, in adition, if alkality sediment system can be incorporated into welding rod and a proper amount of vanadium added into welding seam metal the technological performance of welding rod and anti - crack ability of welding seam metal would be greatly improved.
