An experimental study on effects of post weld impact treatment on spot welded steel

Post Weld Impact Treatment (PWIT) is an impact treatment method for improving mechanical properties of welded joints. The mechanical properties of the welded joint were reduced due to the distortion and stress corrosion cracking caused by the welding process. This paper focuses on the study of influ...

Post Weld Impact Treatment (PWIT) is an impact treatment method for improving mechanical properties of welded joints. The mechanical properties of the welded joint were reduced due to the distortion and stress corrosion cracking caused by the welding process. This paper focuses on the study of influences of pneumatic impact treatment (PIT) and low blow impact treatment (LBIT) for spot welded joint of similar materials through the mechanical properties. This experiment was conducted with the 1.2mm thickness material of carbon steel with welded single lap shear joint. All the welded samples were tested for its mechanical properties by performing the tensile- shear and hardness test. The study has shown the effect of the tensile shear and hardness which focusing on the base metal (BM), fusion zone (FZ) and heat affected zone (HAZ) of the material after being impact treated. The improvement of the tensile behaviour in such local areas can increase significantly the efficiency of higher carbon steel in the entire structure. This paper deals with the influence of PIT and LBI on mechanical properties in carbon steel spot welded plates to determine other beneficial of treatment effectiveness. The experimental investigations follow the standard of AWS D8.9m which tested using Universal Tensile Test Machine (UTM) and Vickers Hardness tester. Further, the comparison of the tensile strength and hardness value in as-welded (untreated) and treatment samples are to be established. The finding shows that tensile strength is improved, and the fracture location is shifted from critical weld metal to base metal area. © Research India Publications.
