Ultrasonic metal welding yakawanikwa netsaona muma1830s. Panguva iyoyo, iyo yazvino nzvimbo welding electrode yakawedzerwa kune iyo ultrasonic vibration bvunzo, zvakaonekwa kuti yaigona kugadzirwa pasina ikozvino, saka tekinoroji yesimbi inotonhora yekudziya yakagadziridzwa. Kunyange zvazvo ultrasonic welding yakawanikwa kare, kusvika ikozvino, maitiro ayo ekuita haasati ajeka. Zvakafanana ne friction welding, asi pane musiyano. Ultrasonic welding nguva ipfupi kwazvo uye tembiricha yakaderera pane recrystallization; iyo yakasiyanawo nekumanikidzirwa welding, nokuti iyo static pressure inoshandiswa iduku zvikuru pane kumanikidzirwa welding. Zvinowanzotendwa kuti padanho rekutanga reiyo ultrasonic welding process, iyo oxide pane simbi pamusoro inozunguzika tangentially, uye chikamu chinobudikira cheiyo rough surface inoburitsa yakadzokororwa microwelding uye maitiro ekuparadza kuwedzera nzvimbo yekusangana uye kuwedzera tembiricha yewelding zone Yakakwira, deformation yepurasitiki inoitika pakusangana kweiyo weldment. Nenzira iyi, kana kudzvanywa kwekubatana kuri pedyo kune mumwe kune chinhambwe uko simba reatomu rinogona kuita, mubatanidzwa we solder unoumbwa. Kana iyo yelding nguva yakarebesa, kana iyo amplitude ye ultrasonic wave yakakura kwazvo, iyo welding simba ichaderedzwa, kana kutoparadzwa.
Zvimiro zve ultrasonic metal welding
Hunhu hwe ultrasonic simbi welding ndeiyi: hapana chikonzero chekuyerera uye kupisa kwekunze, hapana deformation nekuda kwekupisa, hapana kusara kunetseka, uye zvakaderera zvinodiwa zve pre-welding kurapwa pamusoro peiyo weldment. Kwete chete simbi dzakafanana asiwo simbi dzakasiyana-siyana dzinogona kuiswa welded. Mashizha matete kana mafilaments anogona kubatanidza mahwendefa akakora. Ultrasonic welding ine simba shoma pane yazvino welding, uye inowanzoshandiswa pakushambadzira inotungamira ye transistors kana maseketi akabatanidzwa. Kana yakashandiswa pakuisa chisimbiso welding yemishonga uye zvinhu zvinoputika, inogona kudzivirira kusungirirwa kwakawanda kubva kumishonga inosvibisa nekuda kwezvinhu zvakanyungudutswa, uye haizoputika nekuda kwekupisa nezvimwe zvakadaro.
