5 Laser Welding Quality Mavuto & Solutions

Kumanani ndi zochitika zosiyanasiyana za laser welder

Ndi mphamvu yapamwamba, yolondola kwambiri, kuwotcherera kwakukulu, kusakanikirana kosavuta, ndi ubwino wina, kuwotcherera kwa laser kumagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana ndipo kumagwira ntchito yofunika kwambiri pakupanga zitsulo zowotcherera zitsulo ndi kupanga, kuphatikizapo zankhondo, zachipatala, zakuthambo, 3C. zida zamagalimoto, zitsulo zamakina, mphamvu zatsopano, zida zaukhondo, ndi mafakitale ena.

Komabe, njira iliyonse kuwotcherera ngati si katswiri mfundo zake ndi luso, adzatulutsa zolakwika zina kapena zinthu zosalongosoka, laser kuwotcherera ndi chimodzimodzi. Kumvetsetsa bwino kokha kwa zolakwika izi, ndikuphunzira momwe mungapewere zolakwika izi, kusewera bwino mtengo wa kuwotcherera kwa laser, kukonza maonekedwe okongola, ndi zinthu zabwino. Akatswiri odziwa zambiri mwazomwe adakumana nazo kwa nthawi yayitali, adafotokoza mwachidule zolakwika zina zowotcherera za yankho, kuti afotokozere za ogwira nawo ntchito!

1.Mng'alu

The ming'alu opangidwa laser mosalekeza kuwotcherera makamaka otentha ming'alu, monga crystallization ming'alu, liquefied ming'alu, etc. Chifukwa chachikulu n'chakuti weld umabala lalikulu shrinkage mphamvu pamaso kulimba wathunthu. Kugwiritsa ntchito chodyera mawaya kudzaza mawaya kapena kutenthetsa chitsulocho kutha kuchepetsa kapena kuthetsa ming'alu yomwe ikuwonetsedwa pakuwotcherera kwa laser.

2.Pores mu weld

Porosity ndi vuto losavuta pakuwotcherera kwa laser. Nthawi zonse dziwe la kuwotcherera la laser limakhala lakuya komanso lopapatiza, ndipo zitsulo nthawi zambiri zimatentha bwino komanso mwachangu kwambiri. Mpweya wopangidwa mu dziwe losungunuka lamadzimadzi alibe nthawi yokwanira yothawa chitsulo chowotcherera chisanazizire. Mlandu woterewu ndi wosavuta kupangitsa mapangidwe a pores. Komanso chifukwa malo otentha a laser kuwotcherera ndi ang'onoang'ono, chitsulocho chimatha kuziziritsa mwachangu, porosity yomwe ikuwonetsedwa mu kuwotcherera kwa laser nthawi zambiri imakhala yaying'ono kuposa kuwotcherera kwachikhalidwe. Kuyeretsa workpiece pamwamba pamaso kuwotcherera kungachepetse chizolowezi pores, ndi malangizo kuwomba kudzakhudzanso mapangidwe pores.

3. Kuphulika

Ngati inu kuwotcherera workpiece zitsulo mofulumira kwambiri, zitsulo zamadzimadzi kuseri kwa dzenje loloza pakati pa weld alibe nthawi redistribute. Kukhazikika kumbali zonse ziwiri za weld kumapanga kuluma. Pamene kusiyana pakati pa zidutswa ziwiri za ntchito ndi yaikulu kwambiri, sipadzakhala zitsulo zosungunuka zosakwanira zomwe zilipo kuti zitheke, pamene kuwotcherera m'mphepete kudzakhalanso. Pamapeto siteji kuwotcherera laser, ngati mphamvu akutsikira mofulumira kwambiri, dzenje n'zosavuta kugwa ndi zotsatira zofanana kuwotcherera zilema. Mphamvu yoyezera bwino komanso liwiro losuntha la zoikamo zowotcherera laser zitha kuthetsa kuluma kwa m'mphepete.

4.Undercut

Kuwala kopangidwa ndi kuwotcherera kwa laser kumakhudza kwambiri mawonekedwe a weld pamwamba ndipo kumatha kuyipitsa ndikuwononga mandala. The spatter mwachindunji zokhudzana ndi kachulukidwe mphamvu, ndipo akhoza kuchepetsedwa ndi bwino kuchepetsa kuwotcherera mphamvu. Ngati kulowa mkati sikukwanira, liwiro la kuwotcherera limatha kuchepetsedwa.

5.Kugwa kwa dziwe losungunuka

Ngati liwiro kuwotcherera ndi pang'onopang'ono, dziwe losungunuka ndi lalikulu ndi lonse, chitsulo chosungunula kuchuluka ukuwonjezeka, ndi kukangana padziko n'kovuta kukhalabe katundu wamadzimadzi zitsulo, pakati weld adzamira, kupanga kugwa ndi maenje. Panthawi imeneyi, m'pofunika kuchepetsa mphamvu yamagetsi moyenera kuti mupewe kugwa kwa dziwe losungunuka.
