摘要: In today’s world, aluminium and its alloy is showing promising characteristics for replacing other materials due excellent properties like light weight, corrosion resistance, high strength toughness. Conventional welding these creates some challenges porosity, hot cracking void formation. Ultrasonic gives ultimate solution to problems as the material experience only 30% of melting point temperature. a creative system joining metals composites rapidly safely owing high-frequency vibration consolidated with pressure. The process has widespread application in electrical, automotive, aerospace, medical packaging industry. present research work, numerical model proposed evaluation heat generation deformation friction during welding. developed equipped predicting interface temperature stress distribution ultrasonic their impacts on sonotrode, anvil welded parts. effect tool (sonotrode) shape also studied. Response surface methodology (RSM) Box-Behnken design been implemented experimental setup establish co-relation between parameters viz. pressure, amplitude time output response tensile strength. RSM coupled desirability function utilized optimize desired joint. result compared value found be good agreement.
