Control of Welding Residual Stress for Dissimilar Laser Welded Materials
The most common problem of welding dissimilar metals (DMWs) with respect to residual stresses is the differences in the coefficient of thermal expansion and heat conductivity of the two welded metals. In the present work, a CO2 continuous laser welding process was successfully applied and optimized for joining a dissimilar AISI 316 stainless steel and low carbon steel plates. The Taguchi approa...
متن کاملA Simplified Eigenstrain Approach for Determination of Sub-surface Triaxial Residual Stress in Welds
This paper discusses the localized eigenstrain method, a new technique for the determination of triaxial residual stresses deep within long welded joints. The technique follows from the “Inherent Strain Method” developed by Ueda, which uses a combined experimental and analytical approach to determine the source of residual stress (i.e., “eigenstrain” or, equivalently, “inherent strain”) by sect...
متن کاملUltrasonic Inspection of Pressure Vessel Construction Welds using Phased Arrays
Ultrasonic phased arrays are a new technology that offers considerable potential for inspecting construction welds. Using electronic control of the beam, phased arrays can scan, sweep, steer and focus the ultrasound. Since welds typically produce defects of known character and orientation, phased arrays can be programmed to optimize weld inspections. These inspections include standard ASME-type...
متن کاملMicro-Study of Dissimilar Welded Materials
The dissimilar joint between aluminum/titanium alloys (Al 6082 and Ti G2) were successfully achieved by CO2 laser welding with a single pass and without filler material using the overlap joint design. Laser welding parameters ranges combinations were experimentally determined using Taguchi approach with the objective of producing welded joint with acceptable welding profile and high quality of ...
