拼焊板成形性能的研究现状

Research Status on the Forming Performances of Tailor-welded Boards(TWBs)

近年来国内外学者对拼焊板的开发和应用做了大量的研究工作,其成形性能受到焊接材料、焊接方法、焊缝截面尺寸及焊接热影响区微观组织结构的影响.本文从焊接技术到板材的拉伸性能和塑性成形性能等方面,总结了目前研究所得的数据和结论,为进一步研究拼焊板的加工使用提供了可靠的参考,对生产实践环节也有一定的帮助.

Scholars at home and abroad have done a lot of research on development and applications of TWBs.The forming performances are affected by the factors of material,welding message,section size and micro structure at heat-affected zone（HAZ）.This paper is a summary of data and conclusions got from the current researches ranged from welding technology to tensile properties and plastic forming performances,it will provide a reference for the further study and will be help to the production.
