摘要:
为了提高42CrMo与Q345D异种钢的焊接质量以及焊接接头与母材的匹配度,对42CrMo与Q345D锻焊齿轮进行了埋弧焊接试验及焊接工艺评定。中碳调质钢42CrMo综合性能好,用于锻焊齿轮的齿圈中,而Q345D钢具有较好的低温(-20 ℃)冲击特性,同时具有一定的强度,用于腹板。评定结果显示,焊接接头拉伸、弯曲、冲击等检测结果均满足AWS D1.1: 2010标准要求;焊缝及热影响区均未出现马氏体、魏氏组织等异常组织。研究表明,选择合适的焊接材料及焊接工艺,并严格控制热输入,可获得良好的焊接接头,从而达到与母材强度的良好匹配,降低焊接裂纹倾向;该试验形成的焊接工艺指导书,可用于指导车间焊接生产。
Abstract:
In order to improve the welding quality of dissimilar steel 42CrMo and Q345D, as well as the matching degree of welded joint and base metal, it conducted submerged arc welding test and welding procedure qualification for 42CrMo and Q345D forge welding gear. The comprehensive performance of medium carbon quenched and tempered steel 42CrMo is good, which was used for forge welding gear ring; Q345D steel has good low temperature(-20 ℃) impact characteristics, at the same time has a certain strength, was used for the ventral shield. The qualification results showed that the welded joint tensile, bending and impact test results all can meet the requirements of AWS D1.1:2010 standard; abnormal structure did not appear in weld and heat affected zone, such as martensite, widmanstatten structure and others. Research results indicated that choosing the appropriate welding material and welding process, and strictly control the heat input, can obtain the good welded joint, so as to achieve a good match with the strength of base metal, reduce the welding crack tendency. The welding process instruction formed through this test can be used to guide the welding production.
