| titleOfInvention | Coaxial-type ultrasound resistance coupling welding method |
| abstract | The invention discloses a kind of coaxial-type ultrasound resistance coupling welding device and welding method, the welder includes upper ultrasonic applicator and is coaxially set in its outside upper annular electrode, lower ultrasonic applicator and is coaxially set in its outside lower annular electrode；Upper ultrasonic applicator and/or lower ultrasonic applicator connect the first servo pressurization device, and upper annular electrode and/or lower annular electrode connect the second servo pressurization device；The welding method includes pre-pressing stage, Electroplastic induction solid diffusivity stage, nugget formation stages and ultrasonic vibration crystallisation by cooling stage.Present invention can ensure that ultrasonic vibration is acted at solder joint with resistance heat simultaneously, by ultrasonic bonding together with resistance spot welding process efficient coupling, introduce the cleaning effect of ultrasonic cavitation, and make metal produce electro plastic effect and high frequency ultrasound fine grain to act in welding process, such that it is able to typical case's welding-resistant metal material such as high efficiency, high-quality, the welding non-ferrous metal of low energy consumption and high-strength steel. |
