Welding Simulation

When a material is under mechanical load, the stresses change the velocity of acoustic waves because of acoustoelastic effect. This property can be employed for stress measurement in the material itself when the stress concerns the surface of the material, or in the bulk material. This technique involves with critically refracted longitudinal waves that propagate parallel to the surface, i. e. LCR waves. This paper presents a three dimensional thermo-mechanical analysis to evaluate welding residual stresses in plate-plate joint of AISI stainless steel 304L. After finite element simulation, the residual stresses were evaluated by LCR ultrasonic waves. This paper introduces a combination of “Finite Element Welding Simulation” and “Ultrasonic Stress Measurement using the LCR Wave” which is called as “FELcr”. The capabilities of FELCR in residual stress measurement are confirmed here. It has been shown that predicted residual stress from three dimensional FE analyses is in reasonable agreement with measured residual stress from LCR method.

The purpose of this study is to develop an effective way of automated deburring of precision components. A high power laser is proposed as a deburring tool for complex part edges and burrs. Experimental results for carbon steel and stainless steel are presented. Also, the prediction of the HAZ and cutting profile of laser-deburred parts using finite element method is presented and compared with the experimental results. This study shows that FEM analysis can effectively predict the thermal affected zone of the material and that the technique can be applied to precision components.
