Yakanyanya Tembiricha Kudzora kweLaser Systems uye Maindasitiri Zvishandiso Kubva 2002
Mutauro
Laser welding defects senge makatsemuka, porosity, spatter, kupisa-kuburikidza, uye undercutting zvinogona kuguma nekusarongeka kana kupisa manejimendi. Solutions zvinosanganisira kugadzirisa welding parameters uye kushandisa chillers kuchengetedza kuenderana tembiricha. Mvura inotonhorera inobatsira kuderedza kuremara, kuchengetedza michina, uye kugadzirisa huwandu hwewelding uye kusimba.
Laser welding inzira inoshanda uye yakanyatso shandiswa mumaindasitiri akasiyana. Nekudaro, humwe hurema hwakadai sekutsemuka, porosity, spatter, kupisa-kuburikidza, uye undercutting zvinogona kuitika panguva yekuita. Kunzwisisa zvinokonzeresa kukanganisa uku uye mhinduro dzazvo ndicho chinhu chakakosha pakuvandudza kunaka kwewelding uye kuve nemhedzisiro inogara kwenguva refu. Pazasi pane makuru akaremara anowanikwa mune laser welding uye maitiro ekuagadzirisa:
1. Mitswe
Chikonzero: Kutsemuka kunowanzoitika nekuda kwesimba rakawandisa rekudzikira dziva re weld risati ranyatsosimba. Vanowanzobatanidzwa nekuputika kunopisa, zvakadai sekusimbisa kana kuti liquation cracks.
Solution: Kuderedza kana kubvisa makatsemuka, preheating workpiece uye kuwedzera filler zvinhu zvinogona kubatsira kuparadzira kupisa zvakaenzana, nokudaro kuderedza kushushikana uye kudzivirira makatsemuka.
2. Porosity
Chikonzero: Laser welding inogadzira dziva rakadzama, rakatetepa re weld nekukasira kutonhora. Iwo magasi anogadzirwa mudziva rakanyungudutswa haana nguva yakakwana yekupukunyuka, zvichiita kuti pave nekuumbwa kwehomwe dzegasi (pores) mune weld.
Solution: Kuti uderedze porosity, chenesa workpiece pamusoro zvakakwana usati welding. Pamusoro pezvo, kugadzirisa gwara rekudzivirira gasi kunogona kubatsira kudzora kuyerera kwegasi uye kuderedza mukana wekuumbwa kwepore.
3. Spatter
Chikonzero: Spatter yakanangana nekuwanda kwesimba. Kana simba remagetsi ranyanya kukwira, zvinhu zvinonyunguduka zvakanyanya, zvichikonzera kuti kupfachuka kwezvinhu zvakanyungudutswa kubhururuke kubva mudziva reweld.
Kugadzirisa: Deredza simba rekushongedza uye gadzirisa kumhanya kwewelding kusvika padanho rakakodzera. Izvi zvichabatsira kudzivirira yakawandisa zvinhu vaporization uye kuderedza spattering.
4. Kusvirwa
Chikonzero: Kukanganisika uku kunoitika kana kumhanya kwewelding kuchimhanya zvakanyanya, zvichiita kuti simbi yemvura itadze kugovanisa zvakanaka. Zvinogonawo kuitika kana gap rejoinhi rakafara zvakanyanya, zvichideredza huwandu hwesimbi yakanyungudutswa inowanikwa yekubatanidza.
Solution: Nekudzora simba uye welding kumhanya mukuwirirana, kupisa-kuburikidza kunogona kudzivirirwa, kuve nechokwadi chekuti weld pool inotariswa zvakaringana kune yakakwana bonding.
5. Undercutting
Chikonzero: Undercutting inoitika kana kumhanya kwewelding kwanyanya kunonoka, zvichikonzera dziva rakakura, rakakura re weld. Iyo yakawedzera simbi yakanyungudutswa vhoriyamu inoita kuti zviome kudhonzerana kwepamusoro kubata simbi yemvura panzvimbo, zvichiita kuti inyunguduke.
Kugadzirisa: Kudzikisa simba remagetsi kunogona kubatsira kudzivirira pasi, kuve nechokwadi chekuti dziva rakanyungudutswa rinochengetedza chimiro uye simba mukati mekuita.
Basa reMvura Chiller muLaser Welding
Pamusoro pemhinduro dziri pamusoro, kuchengetedza yakanyanya tembiricha yekushanda kwelaser welder kwakakosha kudzivirira kukanganisa uku. Apa ndipo panopinda mawater chiller. Kushandisa chiller yemvura panguva yelaser welding process kwakakosha nekuti inobatsira kuchengetedza inowirirana tembiricha mu laser uye workpieces. Nekunyatso kudzora kupisa munzvimbo yewelding, mvura inotonhorera inoderedza kupisa-inokanganiswa nzvimbo uye inodzivirira inonzwisisika optical components kubva mukupisa kwekupisa. Izvi zvinogonesa kugadzikana uye mhando yelaser beam, pakupedzisira inovandudza mhando yewelding uye kuderedza mukana wehurema hwakadai sekutsemuka uye porosity. Uyezve, mvura inotonhorera inowedzera hupenyu hwemidziyo yako nekudzivirira kupisa uye nekupa yakavimbika, yakagadzikana kushanda.
Mhedziso: Nekunzwisisa izvo zvinokonzeresa zvakajairwa laser welding defects uye kushandisa zvinobudirira zvigadziriso, senge preheating, kugadzirisa simba nekumhanyisa marongero, uye kushandisa chillers, unogona zvakanyanya kunatsiridza welding mhando. Aya matanho anovimbisa epamusoro-mhando, anoyevedza anoyevedza, uye anogara zvigadzirwa, ukuwo achiwedzera kuita kwese uye hupenyu hweako laser welding michina.
Kuti uwane rumwe ruzivo nezve maitiro ekugadzirisa yako laser welding process ine advanced kutonhora mhinduro, inzwa wakasununguka kutibata.
Tiripo nokuda kwenyu kana muchitida.
Ndapota zadza fomu kuti ubate nesu, uye isu tichafara kukubatsira.
