[ 1 ] - Similar Joining of NiTi Shape Memory Alloy using Nd:YAG Pulsed Laser Welding

In this research similar joining of NiTi shape memory alloy was studied. For this purpose, NiTi alloy in the form of wires with circular cross section possessing martensitic phase structure at room temperature was used. By utilizing Nd:YAG pulsed laser welding method followed by optimizing its technical parameters, a defectless joint in terms of appearance and metallurgical properties was obtai...

[ 2 ] - The effect of surface roughness on 1050 aluminum alloy weld profile welded by pulsed Nd:YAG laser

Surface roughness in the welding processes is one of the important parameters in the laser welded metal connections which affects laser beam absorption directly. When the laser beam is irradiated to the surface of the base metal, the surface roughness plays an important role in the amount of beam absorption and the amount of melting achieved and directly affects the penetration depth. The main ...
