“…This increases the chance of the welded joint to be brittle but elongation decreases [ 91 ]. Figure 6 [ 89 ] shows the effect of heat input in fracture strength of Steel/Al laser welded lap joint. The figure indicates that the fracture strength increases with laser power up to an optimum level and then it started decreasing.…”

In this investigation, the corrosion study was conducted on fiber laser welded joints of AISI 410 and 316L stainless steel plates using hydrochloric acid, basic, and salt medium, behavior in three different pH. The effects of three different corrosive atmospheres were examined using the weight loss method. The test sample which was exposed to 1 N hydrochloric acid medium for 48 Hours resulted in 0.006 g of weight loss. The maximum amount of corrosion was found in the acidic medium whereas the least was observed in the salt medium. The effectiveness of three distinct derivatives of 1H-indole-2,3-dione, each replaced with hydroxyl groups in various positions, in inhibiting corrosion. Among the three derivatives examined, it was observed that those with ortho and para hydroxyl group substitutions exhibited superior inhibitory properties.

“…However, there are structures where laser welding and adhesive bonding can be utilized together. Laser welding is excellent method for joining sheet metal products [3]. The advantage of laser welding is a very low heat input which is why the heat-affected-zone (HAZ) of the laser weld is very narrow [4][5][6].…”

The need to manufacture lightweight structures from ultra-high-strength steels is forcing industry to look for new joining technologies. Hybrid joints are one of the new ways to join materials. This paper investigates joining ultra-high strength steel plates using laser welding and adhesive bonding. Steel used in this paper was abrasion resistant steel (AR600) with tensile strength (Rm) ≥ 2 GPa. Three different epoxy adhesives were used in the experiments. The weld morphologies were investigated using optical microscopy. The mechanical properties of the lap joints were evaluated by hardness measurements and tensile shear tests. Examining the profiles of the joints, it became clear that the adhesive causes an air gap between the plates, which affects the morphology of the joint. The air gap caused by the adhesive increased the width of the weld at the interface of the plates. The width of the weld at the interface was approximately 25% larger in the adhesive-bonded joint. Based on shear strength tests, the use of adhesive in addition to the laser weld significantly improved the shear strength of the lap joint. The shear strength of the best laser-welded and adhesive-bonded joint was approximately 84% higher than that of laser-welded joint.
