Structure-property Interaction in Flux Assisted Tungsten Inert Gas Welding of Austenitic Stainless Steel
Austenitic stainless steel SS304 grade was welded with active Tungsten Inert Gas (TIG) welding process by applying a flux paste made of SiO2 powder and acetone. SiO2 flux application improves the weld bead depth with a simultaneous reduction in weld bead width. The improvement in penetration results from arc constriction and reversal of Marangoni convection. Experimental studies revealed that t...
متن کاملOptimization of Weld Bead Width in Tungsten Inert Gas Welding of Austenitic Stainless Steel Alloy
This paper investigates the effects of process parameters on weld bead width of austenitic stainless steel SS-310 in tungsten inert gas welding. The four parameters namely welding current, type of gas, gas flow rate and included angle of weld plates during butt joint were varied at three levels. The DOE approach was used to design experimental conditions. Orthogonal array L9 was used for carryi...
متن کاملIntegrated Risk Estimation of Metal Inert Gas (mig) and Metal Active Gas (mag) Welding Processes
Taking into account the technical characteristics of the welding processes, associated with the fulfi lling clients’ requirements, the assurance of safe and healthy working places as well as the environment protection the fundamental meaning belongs to the application of the appropriate methods of risk assessment of these processes. The paper presents the results of risk analysis, using an inte...
متن کاملWelding of 304L Stainless Steel with Activated Tungsten Inert Gas Process (A-TIG)
Gas tungsten arc welding is a popular process in those applications requiring a high degree of quality and accuracy. However, this process has a big disadvantage against the substantially high productivity welding procedures. Hence, many efforts have been made to improve its productivity. One of these efforts is the use of activating flux (A-TIG welding). In this study, the performance of A-TIG...
