5 Laser Welding Quality Problems & Solutions

Mavuto ndi Mayankho 5 Abwino Omwe Amawotchedwa ndi Laser

Kukumana ndi zinthu zosiyanasiyana kwa laser welder

Ndi luso lapamwamba, kulondola kwambiri, mphamvu yabwino yowotcherera, kuphatikiza kosavuta kokha, ndi zabwino zina, kuwotcherera kwa laser kumagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana ndipo kumachita gawo lofunikira kwambiri pakuwotcherera zitsulo kupanga ndi kupanga mafakitale, kuphatikiza m'magulu ankhondo, azachipatala, ndege, zida zamagalimoto za 3C, zitsulo zamakaniki, mphamvu zatsopano, zida zaukhondo, ndi mafakitale ena.

Komabe, njira iliyonse yowotcherera ngati siigwiritsidwa ntchito bwino ndi mfundo zake ndi ukadaulo wake, ipanga zolakwika zina kapena zinthu zolakwika, kuwotcherera ndi laser sikusiyana. Kungomvetsetsa bwino zolakwika izi, ndikuphunzira momwe mungapewere zolakwika izi, kuti muyese bwino kufunika kwa kuwotcherera ndi laser, kukonza mawonekedwe okongola, ndi zinthu zabwino. Mainjiniya kudzera mu kusonkhanitsa kwa nthawi yayitali, adafotokoza zolakwika zina zodziwika bwino za yankho, kuti agwiritse ntchito bwino ogwira nawo ntchito m'makampani!

1. Ming'alu

Ming'alu yomwe imapangidwa mu laser continuous welding makamaka ndi ming'alu yotentha, monga ming'alu ya crystallization, ming'alu yosungunuka, ndi zina zotero. Chifukwa chachikulu ndichakuti weld imapanga mphamvu yayikulu yocheperako isanakhazikike. Kugwiritsa ntchito waya wodyetsa kudzaza mawaya kapena kutenthetsa chitsulocho kungachepetse kapena kuchotsa ming'alu yomwe yawonetsedwa panthawi ya laser welding.

2. Mabowo mu weld

Kupindika kwa matope ndi vuto losavuta pakulumikiza laser. Nthawi zambiri dziwe lolumikizira laser limakhala lozama komanso lopapatiza, ndipo zitsulo nthawi zambiri zimapangitsa kutentha bwino kwambiri komanso mwachangu kwambiri. Mpweya womwe umapangidwa mu dziwe losungunuka lamadzimadzi umakhala ndi nthawi yokwanira yotuluka chitsulo chisanazizire. Izi zimakhala zosavuta kuyambitsa mapangidwe a pores. Komanso chifukwa chakuti malo otentha a laser ndi ang'onoang'ono, chitsulocho chimatha kuzizira mwachangu kwambiri, pores yomwe imapezeka mulumikiza laser nthawi zambiri imakhala yaying'ono kuposa fusion welding yachikhalidwe. Kuyeretsa pamwamba pa workpiece musanagwiritse ntchito kungathe kuchepetsa chizolowezi cha pores, ndipo komwe kumachokera kuphulika kudzakhudzanso mapangidwe a pores.

3. Kuphulika

Ngati mulukira chitsulocho mofulumira kwambiri, chitsulo chamadzimadzi chomwe chili kumbuyo kwa dzenje lomwe likuloza pakati pa chitsulocho sichikhala ndi nthawi yogawanso. Kulimba mbali zonse ziwiri za chitsulocho kumapanga kuluma. Pamene mpata pakati pa zidutswa ziwiri za ntchito uli waukulu kwambiri, sipadzakhala chitsulo chosungunuka chokwanira chothandizira kuphimba, ndipo kuluma m'mphepete kudzachitikanso. Pamapeto pa chitsulocho, ngati mphamvuyo yatsika mofulumira kwambiri, dzenjelo limakhala losavuta kugwa ndipo limabweretsa zolakwika zofanana. Mphamvu yolinganiza bwino komanso liwiro loyenda la chitsulocho zimatha kuthetsa kupanga kuluma m'mphepete.

4. Kudula pang'ono

Kuthira kwa madzi komwe kumachitika pogwiritsa ntchito laser welding kumakhudza kwambiri ubwino wa pamwamba pa weld ndipo kumatha kuipitsa ndikuwononga lens. Kuthira madzi kumeneku kumagwirizana mwachindunji ndi kuchuluka kwa mphamvu, ndipo kumatha kuchepetsedwa mwa kuchepetsa bwino mphamvu ya weld. Ngati kulowa kwake sikukwanira, liwiro la weld lingachepe.

5. Kugwa kwa dziwe losungunuka

Ngati liwiro la kuwotcherera ndi lochepa, dziwe losungunuka ndi lalikulu komanso lalikulu, kuchuluka kwa chitsulo chosungunuka kumawonjezeka, ndipo mphamvu ya pamwamba imakhala yovuta kusunga chitsulo cholemera chamadzimadzi, pakati pa chowotcherera chidzamira, ndikupanga kugwa ndi mabowo. Pakadali pano, ndikofunikira kuchepetsa kuchuluka kwa mphamvu moyenera kuti dziwe losungunuka lisagwe.
