Abstract

The invention discloses a laser double-side synchronous welding system with a skin-skeleton structure, relating to a laser double-side synchronous welding system. The laser double-side synchronous welding system aims to solve the problems that a spectroscope is easy to damage by ablation because the traditional welding device with double light beams needs high laser power, and also solve the problems of inconvenience of regulation of laser incident angle, narrow regulation range and limited selection on defocussing amount during welding. The sleeve of the laser double-side synchronous weldingsystem is sleeved on a third pipe barrel; a bearing is arranged between the sleeve and the third pipe barrel; a calibration loop is sleeved on the third pipe barrel; a first junction plate and a wirefeeder are connected by a second junction plate; a heightening block is screwed on the lower end of a fourth pipe barrel; an air cutter is provided with at least one side blowing body hole; a nozzle and a third junction plate are connected via a flexible pipe; two welding devices are oppositely arranged above a clamping device of a test piece to be welded; and a skin-skeleton is clamped on the clamping device of a test piece to be welded. The laser double-side synchronous welding system is suitable for welding the skin-skeleton structure.

Description

technical field [0001] The invention relates to a laser bilateral synchronous welding system, in particular to a laser bilateral synchronous welding system of a skin-skeleton structure. Background technique [0002] In the automotive and aerospace industries, in order to reduce the weight of components and improve the carrying capacity, more and more thin-walled lightweight structures are used, especially the skin-skeleton structure is favored. Compared with riveting and bonding, welding has high production efficiency and high joint strength, and has gradually become one of the most important methods for skin-skeleton structure connection. However, traditional welding methods (such as arc welding and plasma arc welding, etc.) have large heat input, low welding speed, and large welding stress and deformation. [0003] Compared with traditional welding methods, laser welding has many advantages such as high energy density, low heat input, narrow heat-affected zone, large weld...
