Embodiment Construction

[0034] In order to make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions in the present invention will be clearly and completely described below with reference to the accompanying drawings in the present invention.

[0035] The embodiment of the present invention provides a process for laser welding a fish scale seam.

[0036] Generally, the weld obtained by laser welding is a smooth straight line, such as figure 1 (a). In the process of welding this line, the laser is repeatedly turned on / off at different positions with large intervals, and an intermittent weld will be obtained, such as figure 1 As shown in (b), each section of the weld is controlled within a certain length, and its shape is similar to an oblong shape, that is, a single fish scale area. On this basis, if the distance between each weld is shortened, it is superimposed, such as figure 1 As shown in (c), a shape similar to a fish scale pattern is ...

Abstract

The invention discloses a process for laser welding of a fish scale line welding seam. The process is used for achieving fish scale line welding through light emitting control of laser. Stable and attractive fish scale patterns are obtained through a careful design welding process, special fish scale shapes are formed through laser swing patterns, and fish scale pattern welding seams with higher strength are formed through superposition of the special fish scale shapes.

Description

technical field [0001] The invention relates to a laser welding process, in particular to a process for laser welding a fish scale seam. Background technique [0002] Fish scale pattern is a shape of the weld, so named because of its fish scale shape. Fish scale welding is considered to be the world's top welding technology. It reflects advanced craft aesthetics and higher strength; more beautiful fish scale patterns are always pursued by technicians in the field of welding. Usually, fish scale welding is obtained by arc welding. [0003] At present, laser welding has become a very competitive welding method due to its high energy density, small heat-affected zone, and easy automation. It has gradually replaced arc welding and is widely used in machinery, electronics, aviation, instrumentation, etc. manufacturing. However, the weld seam obtained by laser welding is narrow and the surface is relatively smooth. [0004] At present, there are some patented technologies for...
