The invention relates to a sequence welding type automobile forecabin gutter channel structure. A forecabin gutter channel body front assembly is a welded part divided into three segments namely a forecabin gutter channel left end plate, a forecabin gutter channel body and a forecabin gutter channel right end plate, wherein the forecabin gutter channel left end plate, the forecabin gutter channel body and the forecabin gutter channel right end plate are connected into a whole in a welded mode, the forecabin gutter channel left end plate is welded to a left wheel casing in the Z direction, the forecabin gutter channel right end plate is welded to a right wheel casing in the X direction, the side face of the forecabin gutter channel left end plate and the side face of the forecabin gutter channel right end plate are welded to a Shotgun in the Y direction, and the forecabin gutter channel left end plate and the forecabin gutter channel right end plate are made of a material higher in material strength than a material of the forecabin gutter channel body. A forecabin gutter channel body rear assembly and the forecabin gutter channel body front assembly are connected in a welded mode to form an integrated part of a U-type structure, and the forecabin gutter channel body rear assembly is made of a material lower in material strength than the materials of the forecabin gutter channel body front assembly. It is unnecessary to arrange a stiffening beam transversely penetrating through a forecabin gutter channel on the lower portion of the forecabin gutter channel, the weight of a whole automobile can be obviously reduced, the material cost is saved, and the difficulty of punch forming is effectively lowered.
