Friction Crush Welding of Low Carbon Steel AISI—1015 and Stainless Steel AISI—304
摘要
Friction crush welding (FCW) is a method that utilizes friction to create strong bonds between similar and dissimilar materials. Several modern applications need the combining of dissimilar and similar materials via solid-state methods. In this work, the FCW between stainless steel (AISI—304) and low carbon steel (AISI—1015) was investigated experimentally to find the impact of selected welding parameters, specifically feed rate and tool rotational speed, on the bond strength of weldments. Experiments were carried out utilizing different feed rates (15, 30, and 45 mm per min) and different tool rotational speeds (2000, 4000 and 6000 rpm) for analysis. The output data are used to evaluate the optimal settings, and at 6000 rpm and 30 mm/min feed rate, maximum tensile strength of 300 MPa was attained. Tool rotation was determined to be the most significant component in boosting bond strength utilizing the technique. Increase in tool rotation leads to increased bond strength.
