Zvakajairwa Kukanganisa muLaser Welding uye Magadzirisiro Azvo

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 shrinkage dziva re weld risati ranyatsosimba. Vanowanzobatanidzwa nekuputika kunopisa, zvakadai sekusimbisa kana kuti liquation cracks.

Solution: Kuti uderedze kana kubvisa kutsemuka, preheating workpiece uye kuwedzera filler zvinhu zvinogona kubatsira kugovera kupisa zvakanyanya zvakaenzana, nokudaro kuderedza kushushikana uye kudzivirira kutsemuka.

2. Porosity

Chikonzero: Laser welding inogadzira yakadzika, yakamanikana weld dziva nekukurumidza 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 kupfapfaidza kwezvinhu zvakanyungudutswa kubhururuka kubva mudziva reweld.

Solution: Deredza simba rekushongedza uye gadzirisa kumhanya kwewelding kune imwe nhanho yakakodzera. Izvi zvichabatsira kudzivirira yakawandisa zvinhu vaporization uye kuderedza spattering.

4. Kupisa-kuburikidza

Chikonzero: Kukanganisika uku kunoitika kana kumhanya kwewelding kuchimhanya zvakanyanya, zvichiita kuti simbi yemvura itadze kugovanisa zvakanaka. Zvinogonawo kuitika kana gap rejoinhi rakafara zvakanyanya, zvichideredza kuwanda kwesimbi yakanyungudutswa inowanikwa pakubatana.

Solution: Nekudzora simba uye welding kumhanya mukuwirirana, kupisa-kuburikidza kunogona kudziviswa, kuve nechokwadi chekuti weld dziva rinotarisirwa zvakakwana kune rakanyanya bonding.

5. Undercutting

Chikonzero: Undercutting inoitika kana kumhanya kwewelding kuchinonoka, zvichikonzera dziva rakakura, rakakura re weld. Iyo yakawedzera simbi yakanyungudutswa vhoriyamu inoita kuti zviome kudhonzerana kwepamusoro kubata simbi yemvura panzvimbo, zvichiita kuti inyunguduke.

Solution: Kudzikisa kuwanda kwesimba kunogona kubatsira kudzivirira pasi, kuve nechokwadi chekuti dziva rakanyungudutswa rinochengetedza chimiro uye simba mukati mekuita.

Basa re Mvura Chillers muLaser Welding

Pamusoro pemhinduro dziri pamusoro, kuchengetedza tembiricha yekushanda yelaser 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 anofadza, uye akasimba 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.
