The Effects Welding Speed and Focal Length on Mechanical Characteristic of Fiber Laser-Welded Structures of DP600 Dual Phase Steel

Öz:
In this study, the effect of welding speed (3, 3.5, 4 m/min) and focal length (0, 1.4 mm) on themechanical properties of the welded structure was investigated in the overlap type joining of 1.2mm sheet thickness DP600 dual phase steel sheet material by fiber laser welding method. For thispurpose, tensile-shear tests were performed on the samples joined by laser welding method, andthe tensile strength and elongation amounts were determined. Microstructure investigation andmicrohardness measurements of the welded area were carried out. It is determined that weld jointshape and penetration depth changes according to focal length distance and welding speed, andwith the maximum welding speed specimens has the minimum penetration depth. Tensile-shearstrength values decreased depending on the increased welding speed for both focal lengthspecimens. It is observed that the microhardness results were affected by welding speed and focallengths. In 0 mm focal length distance specimens’ hardness values increased according to theincreased welding speed, but for –1.4 mm focal length distance the microhardness valuesdecreased with an increased welding speed. The fracture zones and fracture surface morphologyalso affected by welding speed and focal distance. In 0 mm focal length, all the specimen fracturedin base metal with a ductile fracture morphology, but in the –1.4 mm focal length, specimensfractured from the zones which are closer to HAZ and FZ with a brittle fracture morphology.
