ABSTRACT The current demand for vehicles with high fuel efficiency, improved safety and enhanced crashworthiness qualities is being met by making use of high strength components with tailored mechanical properties which are made using tailor-welded blanks. During their production, the surface of the blank needs to be protected against oxidation and decarburisation. Protective coatings are used to protect the steel surface, with Aluminium-Silicon or Zinc-based coatings being the most popular. This work provides a review on the state-of-the-art as well as the issues associated with the laser welding of coated 22MnB5 grade steel to be used in the production of tailor-welded blanks. The paper provides a summary of existing solutions available to overcome these issues while discussing their limitations and the potential for future work.

涂层22MnB5 淬火钢的激光焊接及其对拼焊板生产的影响

摘要 通过使用具有定制机械性能的高强度部件来满足当前对具有高燃油效率、改进的安全性和增强的耐撞性的车辆的需求,这些部件使用定制焊接的坯料制成。在生产过程中,需要防止毛坯表面氧化和脱碳。保护涂层用于保护钢表面,铝硅或锌基涂层是最受欢迎的。这项工作提供了对用于生产拼焊板的涂层 22MnB5 钢的激光焊接的最新技术和相关问题的回顾。本文总结了可用于克服这些问题的现有解决方案,同时讨论了它们的局限性和未来工作的潜力。缩写和符号列表: AHSS:高级高强度钢;UHSS:超高强度钢;UTS:极限抗拉强度;PHS:淬火钢;HS:热冲压;AR:收到;LWB:激光焊接毛坯;TWB:定制焊接坯料;ARW:焊接时的原样;ARWHS:原样焊接,然后热冲压;HSW:热冲压然后焊接;BM:基材;HSBM:热冲压基材;BOP:珠上板;CR:冷却速度;DIC:数字图像相关;DP:双相;EPMA:电子探针微量分析仪;EDX:能量色散 X 射线光谱;FLW:光纤激光焊接;FZ:融合区;GI:镀锌;GA:镀锌;HAZ:热影响区;LBW:激光束焊接;LME:液态金属脆化;PAG:原奥氏体晶粒;白车身:白车身 超高强度钢;UTS:极限抗拉强度;PHS:淬火钢;HS:热冲压;AR:收到;LWB:激光焊接毛坯;TWB:定制焊接坯料;ARW:焊接时的原样;ARWHS:原样焊接,然后热冲压;HSW:热冲压然后焊接;BM:基材;HSBM:热冲压基材;BOP:珠上板;CR:冷却速度;DIC:数字图像相关;DP:双相;EPMA:电子探针微量分析仪;EDX:能量色散 X 射线光谱;FLW:光纤激光焊接;FZ:融合区;GI:镀锌;GA:镀锌;HAZ:热影响区;LBW:激光束焊接;LME:液态金属脆化;PAG:原奥氏体晶粒;白车身:白车身 超高强度钢;UTS:极限抗拉强度;PHS:淬火钢;HS:热冲压;AR:收到;LWB:激光焊接毛坯;TWB:定制焊接坯料;ARW:焊接时的原样;ARWHS:原样焊接,然后热冲压;HSW:热冲压然后焊接;BM:基材;HSBM:热冲压基材;BOP:珠上板;CR:冷却速度;DIC:数字图像相关;DP:双相;EPMA:电子探针微量分析仪;EDX:能量色散 X 射线光谱;FLW:光纤激光焊接;FZ:融合区;GI:镀锌;GA:镀锌;HAZ:热影响区;LBW:激光束焊接;LME:液态金属脆化;PAG:原奥氏体晶粒;白车身:白车身 焊接状态;ARWHS:原样焊接,然后热冲压;HSW:热冲压然后焊接;BM:基材;HSBM:热冲压基材;BOP:珠上板;CR:冷却速度;DIC:数字图像相关;DP:双相;EPMA:电子探针微量分析仪;EDX:能量色散 X 射线光谱;FLW:光纤激光焊接;FZ:融合区;GI:镀锌;GA:镀锌;HAZ:热影响区;LBW:激光束焊接;LME:液态金属脆化;PAG:原奥氏体晶粒;白车身:白车身 焊接状态;ARWHS:原样焊接,然后热冲压;HSW:热冲压然后焊接;BM:基材;HSBM:热冲压基材;BOP:珠上板;CR:冷却速度;DIC:数字图像相关;DP:双相;EPMA:电子探针微量分析仪;EDX:能量色散 X 射线光谱;FLW:光纤激光焊接;FZ:融合区;GI:镀锌;GA:镀锌;HAZ:热影响区;LBW:激光束焊接;LME:液态金属脆化;PAG:原奥氏体晶粒;白车身:白车身 融合区;GI:镀锌;GA:镀锌;HAZ:热影响区;LBW:激光束焊接;LME:液态金属脆化;PAG:原奥氏体晶粒;白车身:白车身 融合区;GI:镀锌;GA:镀锌;HAZ:热影响区;LBW:激光束焊接;LME:液态金属脆化;PAG:原奥氏体晶粒;白车身:白车身
