Gore replasma rimwe chete, zvinhu zvinonyungudutsa zviviri, gomba remakiyi matatu, kudzika kwekubatana kwe4
Nekuda kwekuvapo kweburi rekiyi, danda relaser, mushure mekuvhenekesa mukati meburi rekiyi, rinowedzera kunyudzwa kwelaser nezvinhu uye rinokurudzira kuumbwa kwedziva rakanyungudutswa mushure mekupararira nezvimwe mhedzisiro, nzira mbiri dzekubatanidza dzinoenzaniswa seizvi.
Mufananidzo uri pamusoro apa unoratidza maitiro ekuwelda nelaser yezvinhu zvakafanana uye chiedza chimwe chete, nzira yekushandura simba inongoitwa chete kuburikidza neburi rekiyi, buri rekiyi nesimbi yakanyungudutswa iri pedyo nemadziro eburi zvinofamba nekufambiswa kwedanda relaser, simbi yakanyungudutswa inofambisa buri rekiyi kubva kumhepo inosara kuti izadze uye mushure mekunyorova, zvichiita musono we weld.
Kana chinhu chinofanira kusungirirwa chiri simbi yakasiyana, kuvapo kwemisiyano muhunhu hwekupisa kuchava nemhedzisiro huru pamaitiro ekubatanidza, senge misiyano munzvimbo dzekunyunguduka, kufambisa kwekupisa, kugona kupisa kwakanangana, uye kuwedzera kwema coefficients ezvinhu zvakasiyana, zvichikonzera kushushikana kwekubatanidza, kushanduka kwekubatanidza, uye shanduko mumamiriro ekristaro esimbi yakasungirirwa, zvichikonzera kudzikira kwehunhu hwemakanika ekubatanidza.
Saka, zvichienderana nehunhu hwakasiyana hwenzvimbo yekuwelding, maitiro ekuwelding akagadzira welding yelaser filler, laser brazing, dual-beam laser welding, laser composite welding, nezvimwewo.
Kuzadza Waya yeLaser
Mukushandiswa kwearuminiyamu, titanium uye copper alloys ne laser, nekuda kwekusapinza chiedza che laser zvishoma (<10%) muzvinhu izvi, plasma inogadzirwa ne photo ine kudzivirirwa kwechiedza che laser, saka zviri nyore kugadzira spatter uye kutungamira mukuumbwa kwezvikanganiso zvakaita se porosity uye cracks. Pamusoro pezvo, hunhu hwe welding hunokanganiswawo kana mukaha uri pakati pezvishandiso wakakura kupfuura dhayamita ye spot panguva yekupusha plate thin plate.
Mukugadzirisa matambudziko ari pamusoro apa, mhedzisiro iri nani yekunamira inogona kuwanikwa nekushandisa nzira yekuzadza. Chinozadza chinogona kuva waya kana hupfu, kana nzira yekuzadza yakatogadzirwa kare inogona kushandiswa. Nekuda kwenzvimbo diki yakatarisana, weld inova diki uye ine chimiro chakakombama zvishoma pamusoro mushure mekunge chinhu chekuzadza chaiswa.
Kusunga Neraser
Kusiyana nekusanganisa welding, iyo inonyungudutsa zvikamu zviviri zvakasungirirwa panguva imwe chete, brazing inowedzera chinhu chinozadza chine poindi yekunyunguduka yakaderera pane chinhu chepasi kune weld pamusoro, inonyungudutsa chinhu chinozadza kuti chizadze nzvimbo iri patembiricha yakaderera pane poindi yekunyunguduka kwechinhu chepasi uye yakakwirira pane poindi yekunyunguduka kwechinhu chinozadza, uye yobva yabatana kuti igadzire weld yakasimba.
Brazing yakakodzera michina yemagetsi inonzwa kupisa, maplate matete, uye zvinhu zvesimbi zvinoshanduka-shanduka.
Uyezve, inogona kuverengerwa muzvikamu zviviri se soft brazing (<450 °C) uye hard brazing (>450 °C) zvichienderana netembiricha iyo brazing material inodziiswa.
Kukwevera kweLaser yeMatanda maviri
Kubatanidza matanda maviri kunoita kuti zvive nyore kudzora nguva nenzvimbo yemwaranzi yelaser, nokudaro zvichigadzirisa kugoverwa kwesimba.
Inonyanya kushandiswa pakushongedza aruminiyamu nemagnesium alloys nelaser, kushongedza splice ne lap plate yemota, kushongedza laser ne deep fusion welding.
Danda repiri rinogona kuwanikwa ne laser mbiri dzakazvimiririra kana nekupatsanura danda ne beam splitter.
Matanda maviri aya anogona kuva musanganiswa wemalaser ane hunhu hwakasiyana hwenzvimbo yenguva (pulsed vs. continuous), mawavelength akasiyana (mid-infrared vs. visible wavelengths) uye masimba akasiyana, ayo anogona kusarudzwa zvichienderana nezvinhu chaizvo zvakagadziriswa.
4. Kukwevera kweLaser Composite
Nekuda kwekushandiswa kwelaser beam senzvimbo yega yekupisa, single heat source laser welding ine simba shoma rekushandura uye mwero wekushandiswa, iyo weld base material port interface iri nyore kugadzira misalignment, iri nyore kugadzira maburi nemaburi nezvimwe zvikanganiso, kuti ugadzirise dambudziko iri, unogona kushandisa hunhu hwekupisa hwezvimwe zvinhu zvekupisa kuti uvandudze kupisa kwelaser pa workpiece, inowanzonzi laser composite welding.
Mhando huru yekusanganisa laser composite ndeyekubatanidza laser nemagetsi, mhedzisiro ye1 + 1 > 2 ndeiyi inotevera.
mushure mechiedza chelaser pedyo ne arc yakaiswa,huwandu hwemaerekitironi hwakaderera zvakanyanya, gore replasma rinogadzirwa ne laser welding rinoderedzwa, izvoinogona kuita kuti mwero wekunyudzwa kwelaser uve nani zvikuru, nepo arc iri pachigadziko chechinhu ichi ichidziisa mberi ichizowedzera mwero wekunyudzwa kwelaser.
2. kushandiswa kwakanyanya kwesimba re arc uye huwandu hwese hwesimbakushandiswa kwesimba kuchawedzerwa.
3, nzvimbo yekushanda kwe laser welding idiki, zviri nyore kukonzera kusarongeka kwechiteshi che welding, nepo kushanda kwekupisa kwe arc kwakakura, izvo zvinogonakuderedza kusarongeka kwechiteshi chekuweldingPanguva imwe chete,Hunhu hwekunamira uye kushanda zvakanaka kwearc kuri kuvandudzwanekuda kwemhedzisiro yelaser beam pa arc inotarisa uye inotungamira.
4, welding nelaser ine tembiricha yepamusoro, nzvimbo yakakura inokanganiswa nekupisa, inotonhodza nekukurumidza uye inosimba, iri nyore kugadzira mitswe nemaburi; nepo nzvimbo ye arc inokanganiswa nekupisa iri diki, izvo zvinogona kuderedza gradient yetembiricha, kutonhora, uye kumhanya kwekusimba,inogona kuderedza uye kubvisa kugadzirwa kwemaburi nemaburi.
Kune nzira mbiri dzakajairika dzekubatanidza zvinhu zvine laser-arc: kusanganisa zvinhu zvine laser-TIG (sezviri kuratidzwa pazasi) uye kusanganisa zvinhu zvine laser-MIG.
Kunewo dzimwe nzira dzekuwelda dzakadai se laser ne plasma arc, laser uye inductive heat source compound welding.
