Claim 2:
3. The automatic welding method according to claim 1, wherein in step (3), an origin of a workpiece coordinate system is set at a position where working features are obvious, and this position is an intersection of multiple planes, or an angular point, which is beneficial to alignment; an X-direction, a Y-direction and a Z-direction of the workpiece coordinate system are consistent with main structural feature directions; that is, the target workpiece (1) is placed in a working area of the basic plane, then a support structure is adjusted to enable the X-direction, Y-direction and Z-direction of the workpiece coordinate system to be basically overlapped with the X-direction, Y-direction and Z-direction of the basic coordinate system, which means that an angle error therebetween is within 2°; then, the origin of the workpiece coordinate system is photographed by the 3D camera (5) to extract origin features the workpiece coordinate system, then coordinates of the origin of the workpiece coordinate system are transformed to the basic coordinate system to obtain a transformation relation between the workpiece coordinate system and the basic coordinate system, and then, the position of the workpiece in the basic coordinate system is obtained.
