Numerical Modeling of Heat Affected Zone Cracking Tendency during Laser and Hybrid Laser-Arc Welding Processes
A two-dimensional thermal elasto-plastic numerical model is developed by finite element method to analyze and compare the mechanical driving factor for heat affected zone (HAZ) liquation cracking during laser welding and hybrid laser-arc welding techniques. Calculations of transient temperatures and cooling rates are used in conjunction with solidification theory to analyze weld pool characteri...
متن کاملNumerical and Experimental Study of Geometrical Dimensions on Laser-TIG Hybrid Welding of Stainless Steel 1.4418
In this paper, a three-dimensional finite element model has been developed to simulate the laser-TIG hybrid welding (HLAW) of stainless steel 1.4418 with thickness of 4 mm. Transient temperature profile and dimensions of the fusion zone and heat affected zone (HAZ) during welding process are calculatedusing finite element method (FEM) and were solved in the ABAQUS/Standard software.The heat sou...

متن کاملEffect of Thermal Cycle on Properties of Welding Heat Affected Zone
In this report T-T-T diagram and CCT-Curve from austenitizing temperature 1200•Ž were researched and then effects of preheat temperatures and welding thermal cycle on properties of heat affected zone were clarified to investigate weldagility of 21/4 Cr-1Mo steel and also we carried out a restraind crack test to investigate crack sensitivity of the steel. The results of experiments are summarize...
متن کاملCritical Analysis of Moving Heat Source Shape for Arc Welding Process of High Deposition Rate
Original scientific paper Analysis of heat source shape is important for comprehending Submerged Arc Welding Process. Here an attempt is made to investigate into the analytical solution of the thermal field related to a high deposition rate based process like SAW. It is assumed that a moving heat source follows Gaussian distribution. The realistic assumptions of the shape parameters are made to...
