The invention discloses an automobile front wheel cover upper stiffening beam assembly and a welding process thereof. The automobile front wheel cover upper stiffening beam assembly comprises an outer plate front part, an outer plate rear part, an inner plate front part and an inner plate rear part, the inner plate front portion and the inner plate rear portion are both connected with a front wheel cover assembly of the automobile, the front end of the inner plate front portion is connected with a front anti-collision beam mounting plate of the automobile, the rear end of the inner plate rear portion is connected with an A-column vertical plate assembly of the automobile, and the inner plate front portion and the inner plate rear portion are in butt joint front and back to form an inner plate structure. The outer plate front portion and the outer plate rear portion are in front-back butt joint to form an outer plate structure, and the edges of the outer plate structure and the inner plate structure are in butt joint welding connection. According to the utility model, the structure is simple, the split structure is beneficial to processing and loading, the welding and loading process is simple and high in feasibility, and the connection problem that spot welding cannot be carried out is effectively solved, so that the problems of welding stop, part deformation and welding precision reduction caused by difficult loading are avoided.

    本发明公开了一种汽车前轮罩上加强梁总成及其焊接工艺,其总成包括外板前部、外板后部、内板前部以及内板后部;所述内板前部和内板后部均与汽车的前轮罩总成相连,内板前部的前端与汽车的前防撞梁安装板相连,内板后部的后端与汽车的A柱竖板总成相连,所述内板前部和内板后部前后对接形成内板结构,外板前部和外板后部前后对接形成外板结构,外板结构和内板结构的边缘对接焊接相连。其结构简单,分件结构利于加工和上件,焊接上件工艺简单且可实施性高,有效解决了无法点焊的连接问题,从而避免了因上件困难导致的焊接停线,零件变形和焊接精度下降的问题。
