“…The final weld zone microstructure, which included epitaxial growth, was generally composed of a dendritic and cellular microstructure, according to the solidification and temperature distribution contour of this region [ 26 ]. Yan et al [ 27 ] also investigated the effects of laser welding variable parameters (welding scanning speed, laser power and nozzle distance) on the mechanical properties, microstructure and temperature distribution of the weld line of Inconel 625 and SS 304. It was found that the power of laser was the most effective parameter on the temperature and melting volume of Inconel 625, as compared to the austenitic stainless steel 304, which was clearly evaporated more, instead of melting, due to having a lower thermal conductivity rate.…”

“…In another study by Ahmad et al [29], the effect of process parameters on weld pool temperature distribution and mechanical properties were reported. Butt welding of 1.0 mm SS 304 and 1.0 mm Inconel 625 was investigated by Yan et al [30]. Mechanical behaviours and microstructural properties of Inconel alloys as well as with steel dissimilar joining are reported in the literature [31][32][33].…”

This paper investigated various aspects of replacing existing micro-resistance spot welding (micro-RSW) with micro-laser spot welding for joining Inconel 718 thin foils to thick 410 steel stack-up to allow faster, non-contact joining together with flexibility in spot positioning and removal of tip dressing required for RSW electrodes. The joint quality was evaluated based on the mechanical strength, microstructural characteristics and joint strength at elevated temperature as these joints are often used for high-temperature applications. Experimental investigations were performed using micro-RSW and micro-laser spot welding to obtain the 90° peel and lap shear specimens, each comprising four spots. The obtained strength from laser joints was significantly higher than that of micro-RSW joints due to larger weld nugget formation and interface width. The process map for obtaining good quality welds was also identified, and about a 17% reduction in joint strength was obtained when welded specimens were subjected to elevated temperature (i.e., 500 °C) in comparison with room temperature. This reduction was compensated for using the flexibility of laser welding to add two extra spots. The overall performance of the micro-laser spot welds was found to be better than the micro-RSW considering joint strength, flexibility in placing the spots and time to produce the welds.

“…As a result of these advantages, laser welding offers higher welding speed and efficiency than conventional arc welding. In addition to these criteria in the production of inox kitchen and hotel equipment, where visuality is at the forefront, the welding process resistance, such as Inconel to stainless steel, by the micro-laser welding method has been a popular research topic of recent years [22][23][24][25].…”

In producing custom-made systems, using a robotic welding line that can fine-tune welding parameters is not economical, and laser welding is usually done manually. The most common operator error in manual welding operations is the angular positioning error between the laser beam and the plate surface. This study introduces a smart handheld welding torch device that assists the welding operator with visual warnings. It measures the sheet surface angle to eliminate angular positioning errors, calculates the appropriate torch holding angles accordingly, and helps the laser welding process with the right angle. For this purpose, this study focused on micro-laser spot welding applications of stainless (inox) kitchen and hotel equipment, and the effect of angular positioning errors on the welding quality was investigated experimentally. Experiments show that when the angle between the surface normal and the welding torch is smaller than the critical welding angle, heat-induced traces or micro-deformations occur on the visible surface of the thin stainless material. In addition, there is a significant decrease in the weld quality, since a large enough weld area cannot be created at large values of this angle. The optimum torch angle range was determined using experimental results for the available laser welding parameters. With a standard welding torch and the smart torch, the welding operator was allowed to repeat the same task, and the payloads of the samples prepared in this way were measured. Test results show that using a smart welding torch with an angular positioning assist system significantly improves welding quality. Breaking force values vary in a wide range of welds made with a standard welding torch, and visual problems such as burning, puncture, and swelling are encountered on the visible surfaces of many samples with high strength values. When the developed smart torch was used, the breaking force remained within the desired reference range, and no visual defects were found in any sample.
