Abstract

The invention discloses a method for testing the shearing mechanical property of a laser welding overlapping weldment and belongs to the technical field of welding. The method is used for testing the shearing mechanical property of the weldment. The method comprises the steps of pretreatment, processing and preparing, balance treatment, measurement of a weld width of a weld joint fitting surface, tensile testing and result calculation and analysis. A test of complete and feasible method for testing the shearing mechanical property of a panel overlapping weldment is given; the technology gap of the method in the prior art is compensated; the mechanical property of the laser overlapping weldment can be effectively tested, thereby ensuring the welding quality of the laser overlapping weldment and the reliability of the laser overlapping weldment in use.

Description

technical field [0001] The invention relates to the field of welding technology, in particular to a method for testing the shear mechanical properties of laser-welded lap joints. Background technique [0002] Welding, also known as welding or welding, is a manufacturing process and technology for joining metal or other thermoplastic materials such as plastics by means of heating, high temperature or high pressure. With the development of laser technology, laser welding has become a new technology in the field of welding. Laser welding is one of the important aspects of the application of laser material processing technology. It is an efficient and precise welding method that uses a high-energy-density laser beam as a heat source. Due to its unique advantages, laser welding has been successfully applied in the precision welding of micro and small parts. [0003] In the field of welding, the welding of plates is often encountered. According to different contact methods, plat...
