Kusanthula kwachitsanzo kwa ntchito zowotcherera za laser zokhala ndi ma diameter osiyanasiyana

Kukula kwa mainchesi a laser pachimake kudzakhudza kutayika kwa kufalikira ndi kachulukidwe kake kagawidwe ka kuwala.Kusankha koyenera kwa mainchesi apakati ndikofunikira kwambiri.Kuchulukirachulukira kwapakati kumabweretsa kusokonekera komanso kubalalitsidwa pakupatsirana kwa laser, kukhudza mtundu wa mtengo komanso kulondola kwambiri.Kuchepa kwapakati pakatikati kumachititsa Kufanana kwa mphamvu yamagetsi yamagetsi yamtundu umodzi kumakhala koipitsitsa, zomwe sizingathandize kufalitsa kwa laser-high-power.

1. Ubwino ndi ntchito yaing'ono pachimake awiri lasers (<100um)

Zinthu zonyezimira kwambiri: aluminium, mkuwa, chitsulo chosapanga dzimbiri, faifi tambala, molybdenum, etc.;

(1）Zida zowunikira kwambiri zimafunikira kusankha laser yaying'ono yapakati.The mkulu mphamvu kachulukidwe laser mtengo ntchito kutenthetsa zinthu mwamsanga liquefied kapena vaporized boma, amene bwino laser mayamwidwe mlingo wa zinthu ndi kukwaniritsa imayenera ndi mofulumira processing.Kusankha laser yokhala ndi mainchesi akulu kumatha kubweretsa kuwunikira kwambiri., zomwe zimatsogolera ku kuwotcherera pafupifupi komanso ngakhale kuwotcha kwa laser;

Zipangizo zotha kuthyoka: nickel, nickel-plated copper, aluminium, chitsulo chosapanga dzimbiri, titaniyamu aloyi, etc.

Izi nthawi zambiri zimafunikira kuwongolera kokhazikika kwa malo omwe amakhudzidwa ndi kutentha ndi dziwe laling'ono losungunuka, kotero ndikofunikira kusankha laser yaying'ono yapakati;

High-liwiro laser processing:

(3）Zozama kulowa kuwotcherera kumafuna mkulu-liwiro laser processing, ndipo m'pofunika kusankha laser ndi mkulu kachulukidwe mphamvu kuonetsetsa kuti mzere mphamvu zokwanira kusungunula zinthu pa liwiro, makamaka kuwotcherera lap, kuwotcherera malowedwe, etc. zimafuna kuya kwapamwamba kolowera.Ndi bwino kusankha yaing'ono pachimake awiri laser oyenera.

2. Ubwino ndi kugwiritsa ntchito kwa lasers yayikulu m'mimba mwake (> 100um)

Large pachimake m'mimba mwake ndi malo aakulu, lalikulu kutentha kuphimba dera, malo ochitirapo zambiri, ndipo kokha yaying'ono kusungunuka kwa zinthu pamwamba zimatheka, amene ali oyenera kwambiri ntchito laser cladding, laser remelting, laser annealing, laser kuumitsa, etc. minda iyi, lalikulu kuwala malo zikutanthauza mkulu kupanga dzuwa ndi zofooka m'munsi (kuwotcherera matenthedwe conductive pafupifupi alibe chilema).

Pankhani ya kuwotcherera, malo akuluakulu amagwiritsidwa ntchito kwambiri pakuwotcherera kompositi, komwe kumagwiritsidwa ntchito pophatikiza ndi laser yaying'ono pachimake: malo akulu amapangitsa kuti zinthuzo zisungunuke pang'ono, kusinthika kuchokera ku olimba kupita kumadzi, zomwe zimasintha kwambiri mayamwidwe. za zinthu laser, ndiyeno amagwiritsa ntchito pachimake yaing'ono Pochita izi, chifukwa preheating kwa malo lalikulu, pambuyo processing, ndi kutentha lalikulu gradient kuperekedwa kwa dziwe losungunuka, zinthu sizimachedwa ming'alu zilema chifukwa. ndi kutentha kofulumira ndi kuzizira kofulumira.Itha kupangitsa mawonekedwe a weld kukhala osalala ndikukwaniritsa spatter yotsika kuposa njira imodzi ya laser.
