PROBLEM TO BE SOLVED: To provide a welding method and welding equipment for more rapidly and more accurately detecting a weld line. SOLUTION: An automatic welding equipment 1 highly accurately specifies the position coordinate of the weld line 13c in respective positions and creates the actual trajectory information of a welding torch 2 by performing touch sensing in three or more places in a plurality of respective positions (position y<SB>1</SB>, y<SB>2</SB>, ... y<SB>n</SB>) along the weld line. At that time, the position coordinate of the weld line 13c is highly accurately specified by performing touch sensing in the minimum places, it is made possible to perform the detection of the actual weld line more rapidly as a result. Further, since the touch sensing is performed by making a shielding nozzle 3 touch a workpiece (actual workpiece) 13, the position detection is highly accurately performed.
