Example Embodiment
[0021] Such as figure 1 As shown, the present invention is a method for controlling the welding deformation of a telescopic rudder propeller base cylinder. The telescopic rudder propeller base includes a cylinder and a flange. The flange is horizontally arranged at the top of the cylinder. The bottom end of the body is welded to the hull, and the welding of the bottom end of the cylinder to the hull specifically includes the following steps:
[0022] S1. Divide the outer circumference of the top of the cylinder into multiple measuring sections. The number of measuring sections increases according to the increase in the diameter of the cylinder. A measuring point is set at the middle of each measuring section. The plurality of measurement sections are provided with a plurality of welding sections in one-to-one correspondence, and each measurement point has a corresponding projection point on the welding section, and the flange flatness is measured by the laser theodolite through th...
