Porosity Defect Analysis in ST 37 Steel Welding Joints Using the Dye Penetrant Method

Porosity Defect Remodeling and Tensile Analysis of Cast Steel

Tensile properties on ASTM A216 WCB cast steel with centerline porosity defect were studied with radiographic mapping and finite element remodeling technique. Non-linear elastic and plastic behaviors dependent on porosity were mathematically described by relevant equation sets. According to the ASTM E8 tensile test standard, matrix and defect specimens were machined into two categories by two t...

Optimization of the parameters of low-carbon steel (EN10130) welding using friction stir welding method

  Friction-stir welding process is a novel method of solid state welding, which produces heat due to friction between the pin, the shoulder and the workpiece. This heat causes a paste area. Shoulder pressure and pin spin cause edges integration and lead to welding. In this study, firstly, the feasibility of welding of steel sheet (EN10130) with a thickness of 1.5mm has been tested by 58 experim...
