中文摘要 | 本研究以氬銲法對鍛造模具進行表面耐磨材料之銲覆造形。本研究之經驗認為在 4340 上銲覆高速鋼時,宜以三明治方式,在中間插銲一層 SKD 61 銲道。 採用直線跳銲法 ,並使用 400 ℃以上之高預熱與層間溫度。如此程序可得一無龜裂之銲覆層。 |
英文摘要 | In this study, TIG was used to overlay high-speed steel layer on the 4340 steel forging mould. Before overlaying, a cavity in the mould was pre-formed. The experience of our work showed that it would be much easier to get a noncracking high-speed steel overlayer if the following procedures were taken during welding: (1) to overlay a H13 layer before overlaying the high-speed steel layer. (2) to take a straight, non-weaving weldpass along the long axis of the mould. (3) to take an intermittent weld sequence. (4) to take a high preheat and interpass temperature. (avove 400℃) |
