Abstrakt

Resistance spot welding is a popular metal joining process which is widely used in automobile industry, household and domestic appliances manufacturing industry, and fabrication industry like air craft manufacturing industries [10]. Experimental investigation carried is out on inner and outer sleeve which is used in stove manufacturing industry. Material taken is stainless steel SS304 for experiment having thickness 0.5 mm. Experimental investigation is based on two defects which are interfacial separation and improper nugget diameter in spot welding. For this investigation, welding current and welding cycle time are taken as main parameters affecting the defect. Ultrasonic pulse echo inspection is a non-destructive testing which is used for checking whether the internal flow or defect is taking place during spot welding or not. For ultrasonic testing, Einstein-II TFT ultrasonic flaw detector machine is used. It records various echoes during testing and is used for various analyses purposes.Cite this ArticleHindocha Hardik P.
