Ungawukhetha Kanjani Umshini Welding Laser

Imishini yokushisela i-laser yasungulwa okokuqala ku 1970s. Baqala ukusetshenziswa ekukhiqizeni ngobuningi endaweni 1990s futhi ibe nesandla emikhakheni yezimoto nezimboni kusukela ngaleso sikhathi. Ukunemba kwazo kanye nezindleko eziphansi zokusebenza kuyathandeka kakhulu, futhi kubhekwa njengenye indlela engcono kune-resistance spot welding. Ibhizinisi lemishini yokushisela i-laser lingaba nenzuzo enkulu uma lenziwe kahle, ngakho lo mhlahlandlela uchaza ukuthi amabhizinisi nosomabhizinisi bangangena kanjani kulo. Ukukhetha imishini efanelekile akufanele kube nzima, futhi lo mhlahlandlela ukukhombisa ukuthi yini okufanele uyibheke.

Umshini wokushisela we-laser: isabelo semakethe kanye nesidingo

Usayizi wemakethe wemishini yokushisela i-laser kulindeleke ukuthi ukhule ngo $ 373 million kusukela ngo-2021 kuya ku-2025 futhi $ 1.12 billion ngo-2030. Izinga lokukhula konyaka nonyaka lika-2021 lalinjalo 4.48%. Phakathi kwezitayela ezivelayo embonini yokushisela i-laser ukukhiqiza okungeziwe. Ukukhiqiza okungeziwe kwenza kube nokwenzeka ukukhiqiza imikhiqizo enejometri eyinkimbinkimbi. Ngaphezu kwalokhu, ithuthukisa ukusetshenziswa kwezinto ezibonakalayo futhi inciphise ukumoshwa. Imishini yokushisela i-laser nayo iyamukelwa ekwenziweni kwezimoto ukukhiqiza izingxenye zenjini, ama-alternator, ama-solenoid, nezihlungi zikaphethiloli.

Izinto okufanele uzicabangele lapho ukhetha umshini wokushisela we-laser

I-Laser pulse waveform

Lapho ugongolo lwe-laser olunamandla aphezulu luqondiswe phezu kwensimbi, 60-98% amandla e-laser abonakaliswa kude, okubangela ukuguquka kwezinga lokushisa laleyo ndawo. Lokhu kucatshangelwa okubalulekile lapho wenza i-wafer welding.

Imvamisa yama-laser pulses

Imvamisa yama-laser pulses yikhono lokubonisa ama-pulses. Ikalwa njengama-pulses abonisiwe ngomzuzwana futhi kusetshenziswa iyunithi i-Hertz (Hz). Lapho i-frequency iphezulu, iba mncane usayizi we-laser, okusho ukuthi inganqamula izinsimbi kalula ngomthombo we-laser ongashintshi. Ngaphambi kokushisela, amandla e-laser akhiqizwayo kufanele anele ukuncibilikisa insimbi ukuze ishise. Ijubane lokucubungula lingasetshenziswa ukunquma imvamisa yokuphuma kwe-laser.

Ukuminyana kwamandla

Ukuminyana kwamandla okuphezulu kubangela ukuhwamuka kumasekhondi amancane ongaphezulu kwento eshiselwayo ibe yindawo yokubila. Ukuminyana kwamandla aphezulu kunenzuzo ekususeni izinto ezifana nokusika, ukuqopha, nokubhoboza. Ukwandisa ukuminyana kwamandla ku-1.5 MW/cm² futhi ngale kushintsha i-weld iye kwimodi yokhiye/yokungena. Ukuminyana kwamandla aphansi kufinyelela endaweni yokubilisa ama-millisecond ambalwa. Ngaphambi kokuhwamuka komhlaba, ungqimba olungezansi lufinyelela endaweni encibilikayo luyenze ifanelekele ukushisela okuhlanganisiwe. Yaziwa nangokuthi i-conduction welding futhi idinga ukuminyana kwamandla ka-0.5 MW/cm².

Ububanzi be-Laser pulse

Amagagasi e-Laser akhiqizwa ngama-pulses. Ububanzi be-Pulse bubhekisela ebangeni eliphakathi kwama-pulse amabili. Ibanga phakathi kwama-pulses amabili lingashintshwa ukuze lithinte amandla akhishiwe. Lapho ububanzi bokushaya kwenhliziyo buphansi, amandla akhishwa i-laser ayancipha. Ububanzi be-pulse futhi yipharamitha eyinhloko yokunquma ivolumu nezindleko zemishini yokucubungula.

Umthombo we-Laser

Kunezinhlobo ezintathu zemithombo ye-laser: i-fiber, i-C0₂, kanye no-Nd:YAG. I i-fiber laser ilungele ukusebenza izingxenye zensimbi. C0₂ ama-laser welders ahlinzeka ngogongolo lwe-welding oluqhubekayo oludala ama-welds asebenzayo futhi ahlala isikhathi eside. Ama-laser we-Nd:YAG asebenzisa amandla amancane kune-fiber lasers. Kodwa-ke, banokulawula okukhulu kwe-laser okungenakufinyelelwa ngezinye izinhlobo ze-laser.

Izinhlobo zemishini yokushisela i-laser

I-laser ye-pulsed

• Ibiza kakhulu kune-laser pulsed.

Imakethe eqondiwe yemishini yokushisela i-laser

Imishini yokushisela i-laser kulindeleke ukuthi ikhule ku-CAGR ye 4.8% ngesikhathi sokubikezela 2022-2032. Isifunda sase-Asia Pacific kulindeleke ukuthi sibe nesabelo esikhulu kunazo zonke emakethe yemishini yokushisela i-laser. Izinto ezinomthelela kulokhu kubusa ukwanda kokuqwashisa ngobuchwepheshe be-laser welding kanye nokukhula kwezimboni zezimoto nezokuthutha. I-Europe kulindeleke ukuthi ilahlekelwe isabelo sayo semakethe yomshini we-laser welding ngenxa yokushoda kwezinto ezingavuthiwe kanye nemiphumela emibi yenkinga yezomnotho. INyakatho Melika izophinde ilahlekelwe isabelo sayo semakethe kwezomnotho ezisafufusa esifundeni se-APAC.

Imicabango yokugcina ngemishini yokushisela

I-laser welding ikhethwa kunezinye izinhlobo zokushisela ngezizathu ezihlukahlukene. Okubaluleke kakhulu ukuntuleka kokugqokwa kwemishini kanye nokusetshenziswa kwama-electrode ekushiseleni. Lokhu kungaphezu kwalokho okuzenzakalelayo ukushisela ngosizo lwesoftware yeComputer-Aided Design (CAD). Vakashela Chovm.com ngokukhethwa kwemishini yokushisela i-laser etholakalayo.
