In April 2019, Tong Hi-Tech undertook the replication line reconstruction project of FAW-Volkswagen (Changchun Base) Welding and Welding Plant No. 2 and was responsible for the "turnkey project" of the new side wall door laser fusion welding station project for 3 types of vehicles including CCSB. The process was first developed in 2001 by ThyssenKnuber of Germany for a variety of high-end models of German Volkswagen and Audi. In recent years, it has been successfully introduced into the domestic market, mainly for the side panel inner and outer panel areas, which can realize multi-layer carbon steel plates. Compared with the narrow flange side of high-strength steel plate, compared with the traditional spot welding, it has many functional, technological and efficiency advantages:

该项目是长春一汽大众二工厂的复制线改造项目,主要提升CC及迈腾等高端车型的产能,其中侧围门洞激光深熔焊工位位于主线补焊线上。

激光焊接房与激光源房采用分体式设计,激光源房坐落在单独设计的钢结构平台上,激光焊房采用串联双工位布局,每个工位左右对称设置了6台激光焊机器人,大幅度地提高了自动焊接效率、减少了补焊线工位数量,同时也能作为设备故障互备的方案。 

Ø 工位规划50JPH,节拍CT=61.5s,预留提升60JPH;

Ø 工位规划3+1车型,设备可满足无限制车型导入;

Ø 配合使用4kw激光器,焊接速度≥45mm/s;

Ø 焊接法兰缩减50%以上,连接强度提升30%以上;

Ø 采用蒂森LSK05双压指激光熔焊头,可实现多层板无夹具的焊接工艺,自带的浮动功能,可最大限度的补偿工件的误差;

Ø 激光熔焊系统采用世界先进主流工艺设备配置,可实现高品质焊接质量要求;

Ø 工位采用同高科技自主研发的双层铝合金的防护系统,并通过德国TUV安全检测及认证;
