Transient and Residual Thermal Strain-Stress Analysis of GMAW
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A three-dimensional transient thermomechanical analysis has been performed for the Gas Metal Arc Welding process using the finite element method. Because the heat generated due to elasto-visco-plastic ...
Control of Magnesium Loss During Laser Welding of Al-5083 Using a Plasma Suppression Technique
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A major problem of autogeneous laser welding Al-5083 is the loss of magnesium by evaporation or plasma formation. This consequently results in welds of low tensile strength and unacceptable ...
