چکیده مقاله:
In this project, joining Ti-6Al-4V and stainless steel plates by pulsed-laser-welding method using pure copper and silver interlayers has been studied. The process of lapwelding the plates was done by a pulsed laser system, using concentric spot welding of 0.8mm-diameter circles around a 4mm radius circle. The next phase included examining whether joining was successful and whether cracks were found. Then, optical and electron microscopy inspections, and chemical (spot-scan & map-scan) analyses were performed. Finally, tensile strength and microhardness were tested. The best joining result occurred in 7 milliseconds when copper was used as the interlayer and stainless steel was placed above (near the laser).
