| 摘 要： | 采用堆焊焊条CHR322,在A3钢基体上以不同的焊接工艺进行手工电弧堆焊试验。分析了堆焊熔敷金属的显微组织,研究了焊接线能量对堆焊层金属显微组织形成的影响。分析研究表明：堆焊金属与基体金属具有良好的冶金结合,第一层堆焊金属受基体金属的稀释程度影响明显。堆焊金属的显微组织与输入的焊接线能量的大小有关。

| Abstract: | Surfacing process is conducted on the substrate of steel A3 by shielded metal arc welding process using electrode CHR322 under different welding current conditions.The microstructure of the deposited metal and the effect of the welding heat input on the formation of the deposited metal are studied.The results show that a good metallurgical bonding of the substrate and the deposited metal is obtained,the dilution effect of the substrate metal on the first pass deposited metal is obvious and the microstructure of the deposited layers is related with the value of the welding heat input. |
