Embodiment Construction
[0053] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.
[0054] according to figure 1 As shown, the welding seam tracking measurement method provided by the present invention specifically includes the following steps:
[0055] 【S1】Using a single laser beam to scan the weld and both sides of the weld along the length of the weld.
[0056] The specific method of scanning with laser beam:
[0057] Irradiate a single laser tube at a fixed angle to a polygonal prism rotating at a fixed speed;
[0058] A single laser beam is reflected by the rotating polygon mirror to form a continuously variable angle scanning laser beam scanning the surface area of the weld. Such as figure 2 Shown.
[0059] [S2] The scanning laser beam is reflected by the welding seam and the areas on both sides of the welding seam to form...
