Welding positioning line tool moulding bed and welding positioning line lineation method

The invention relates to the technical field of high-rise building high structure component manufacture, in particular to a welding positioning line tool moulding bed and a welding positioning line lineation method. The welding positioning line tool moulding bed is used for carrying out positioning line lineation on the hinging hole of a connecting plate and comprises a first sample plate and a first extension part, wherein the first sample plate is provided with a first positioning edge used for being positioned with the hinging hole; the first extension part is arranged on the first sample plate and is provided with a first lineation edge parallel with the first positioning edge; and an interval between the first positioning edge and the first lineation edge is equal to the radius of thehinging hole. The first sample plate and the connecting plate are arranged in parallel, the first positioning edge and the edge of the hinging hole are aligned, at the time, a position correspondingto the first lineation edg
