The invention discloses a projection welding structure of an automobile body connecting reinforce. The structure comprises a reinforcing pipe and a stamping part, and a through hole is formed in the stamping part; three convex hulls are arranged on the stamping part, and the three convex hulls are uniformly distributed around the through hole; the bottom end of the reinforcing pipe is welded to the three convex hulls, welding is easy, the strength is enough, welding can be conducted in a small space, welding thermal deformation is hardly affected, the welding time is shortened, and therefore the production cost is reduced. The invention further discloses a projection welding process of the automobile body connecting reinforcer, the three convex hulls on the stamping part are molten duringprojection welding, so that the stamping part and the reinforcing pipe are welded together, the welding strength is enhanced, welding can be conducted in a small space, welding thermal deformation isprevented, and the production cost is reduced.

    本发明公开了一种汽车车身连接加强件的凸焊焊接结构,包括加强管和冲压件,所述冲压件上开设有通孔;所述冲压件上设置有三个凸包,且所述三个凸包均布在所述通孔的周围;所述加强管的底端焊接在所述三个凸包上,焊接简单,不仅强度够,还可以在小空间焊接,焊接热变形几乎没有影响,焊接时间也变短了,从而也降低了生产费用。本发明还公开了一种汽车车身连接加强件的凸焊焊接工艺,冲压件上的三个凸包在凸焊焊接时熔化从而将冲压件和加强管焊接在一起,增强焊接强度,可以在小空间焊接,且防止了焊接热变形,降低了生产费用。
