The distortion of laser welded titanium plates was assessed for different operating conditions of the laser welding device, and with different welding parameters (in terms of weld point and prewelding). In this study, Nd : YAG laser welding device was used to join the titanium plates. The results showed that distortion increased stepwise after each welding point along the welding zone (one-side...

The study focused on the standalone TIG and MIG welding combined effect, emphasizing microstructural properties strength of welded joint, especially heat-affected zone. literature revealed that both techniques their combination have full penetration in terms weld, HAZ for TIG-MIG has a larger width comparison with MIG. joints usually demonstrate ductile fracture compared or joints. However, it ...

Two laser transmission welding experiments involving polyvinyl chloride are presented that aim to validate a previously presented welding model while helping to further understand the relationship between welding parameters and weld quality. While numerous previous research papers have presented the results of laser welding experiments, there exists minimal work validating models of the welding...

Because of their construction and flexibility, industrial robots are suitable to be used, with a laser source and an optical fiber, for laser welding of 3D products. However, the positioning accuracy of robots are insufficient for laser welding. Also the product and clamping tolerances are too wide for laser welding. These problems can be solved by applying sensors, which measure the location o...

This paper provides a general introduction to welding fundamentals (section 2) followed by sections on a few selected welding processes that have had significant developments or improvements over the last few years. The processes that are discussed are friction welding (section 3), hot plate welding (section 4), ultrasonic welding (section 5), laser/IR welding (section 6), RF welding (section 7...

The simulation method in laser-MIG hybrid welding, which involves two heat sources and multiple welding parameters, is beneficial to reveal the complex physical phenomena dynamic behavior of molten pool keyhole during process. In this investigation, for 6-mm-thick 6061 aluminum alloy was performed under different input by high-power disc laser, MIG system, KUKA robot. high-speed camera system u...

Laser welding is a widely used but complex industrial process. In this work, we propose the use of an integrated machine intelligence architecture to help address the significant control difficulties that prevent laser welding from seeing its full potential in process engineering and production. This architecture combines three contemporary machine learning techniques to allow a laser welding c...
