More Information
Summary:Joined tube frame for vehicles. The present invention aims to provide a pipe frame structure for vehicles that is capable of reducing the number of component parts to simplify construction while improving the freedom of design of the pipe frame. A joined pipe frame for vehicles according to the present invention is therefore formed with a plurality of rough pipes P1, P2, ..., Pn which differ in thickness or material and which are identical in external configuration in their joined regions opposite. The rough tubes are butt welded end to end with laser beam welding so that weld bead b can be prevented from protruding and the thin walled rough tube P2 cannot be sufficiently attached by its end to the opposite end of the corresponding thick-walled tube. When the tube frame has bent portions, the rough tubes P1, P2 ..., Pn are straight butt welded first end to end with each other and then bent to a given shape.
