Mfundo Zazikulu Zokhudza Weld Quality
Resistance welding imagwiritsa ntchito kutentha kwa magetsi. Pamene panopa akudutsa mbale ziwiri zitsulo kuti welded, kutentha mkulu kwaiye kukana mu kuwotcherera dera amasungunula mbale, amene kenako anagwirizana pansi pa mavuto ndi utakhazikika. Kukaniza kuwotcherera kumakhala ndi magawo awiri: kukana kukhudzana pakati pa mbale zachitsulo ndi kukana kwa thupi kwa mbale zomwezo. Chifukwa chake, kuti mukwaniritse weld wabwino, ndikofunikira kuchepetsa kukana kukhudzana ndikuwonjezera kukana kwa thupi kwazinthuzo.
Kuti muwongolere mtundu wa weld, magawo asanu otsatirawa ayenera kusinthidwa: kukana kuwotcherera, kuthamanga kwa kuwotcherera, kuphatikizika, liwiro la kuwotcherera, ndi chinthu china chosinthika - tinplate. Zinthu izi zimatsimikizira ma weld nugget spacing, kuchuluka kwa kusungunuka, mawonekedwe, ndi mawonekedwe ang'onoang'ono a ma weld nuggets. Ma parameter awa ndi ogwirizana; pamene chizindikiro chimodzi chikusintha, zowotcherera ziyenera kukonzedwanso.
(1) Ubale Pakati pa Kuwotcherera Kuthamanga ndi Kuwotcherera PanopaZinthu zina zimakhalabe zokhazikika, kuti mupeze chowotcherera chabwino, liwiro la kuwotcherera ndi kuwotcherera pakali pano liyenera kuonetsetsa kuti tinplate imasungunuka bwino ndipo ma weld nuggets akugwirizana. Pamene kuwotcherera liwiro likuwonjezeka, panopa ayenera kuchuluka. Ngati liwiro la kuwotcherera lili lotsika kwambiri, tinplate imatha kutentha kwambiri, zomwe zimapangitsa kuti ma weld nuggets azizire pang'onopang'ono kuposa ma contract a tinplate, zomwe zimapangitsa kuti pakhale mabowo akulu. Mosiyana ndi zimenezi, ngati kuwotcherera liwiro ndi mkulu, zingachititse wosagwirizana weld nuggets. Kuphatikiza apo, kutentha kosakwanira kwa tinplate kumatha kupanga mabowo otalikirapo kapena zitsulo za malata pakati pa mbale.
(2) Ubale Pakati pa kuwotcherera Kupanikizika ndi kuwotcherera CurrentThe wosanjikiza malata pa tinplate pamwamba ndi wabwino conductive zitsulo ndi otsika kukana, ndi otsika kuuma kumapangitsa kuti mosavuta deformable pansi mavuto, kwambiri kuchepetsa kukana padziko ndi kutsogolera kuwotcherera. Kuwotcherera pakali pano kumawonjezeka ndi kuthamanga kwa kuwotcherera chifukwa kuthamanga kwakukulu kumawonjezera malo okhudzana ndi tinplate, kuchepetsa kukhudzana ndi kukhudzana kwapamwamba, motero kumafunika kuwonjezeka kwapang'onopang'ono kwa kuwotcherera panopa. Kuthamanga kwa kuwotcherera kuyenera kusinthidwa mkati mwazoyenera. Ngati kupanikizika kuli kochepa kwambiri, mkanda wowotcherera udzakhala wapamwamba, zomwe zimasokoneza zokutira kukonza. Mosiyana ndi zimenezi, kuthamanga kwambiri kuwotcherera kumakwaniritsa mosavuta msoko wa weld.
(3) Ubale Pakati pa Kuphatikizika ndi Kuwotcherera CurrentKuphatikizana kokulirapo kumafuna kutentha kwapang'onopang'ono, kotero kuti kuwotcherera kumawonjezeka ndikuphatikizana. Pansi pa zinthu zomwe zimayikidwa kuwotcherera, ngati kuphatikizika kuli kokulirapo kuposa momwe zimakhalira, malo omwe ali ndi mphamvu yowotcherera amawonjezeka, kuchepetsa kachulukidwe kakachulukidwe kakuwotcherera ndikuwonjezera kukana kukhudzana, zomwe zimapangitsa kuti pakhale kutentha kosakwanira kwa kuwotcherera ndi kuzizira kozizira. Mosiyana ndi zimenezi, kuchepetsa kuphatikizikako kungayambitse kuwonjezereka komanso kuwonjezeka kwa extrusion.
(4) Mphamvu ya Tinplate Properties pa Welding
1. Kulemera kwa Tin Kupaka Kulemera kwa malata pa tinplate kumakhudza ubwino wa weld. Ngakhale wosanjikiza malata ali otsika kukhudzana kukana ndipo ndi kondakitala wabwino, ngati malata ❖ kuyanika kulemera ndi otsika kwambiri (zosakwana 0.5 g/m²), ndi aloyi wosanjikiza ndi mkulu, kukhudzana pamwamba kukana kwa aloyi wosanjikiza ndi zazikulu, zomwe zimawononga kuwotcherera khalidwe. Makamaka pagulu lomwelo la tinplate, ngati aloyi wosanjikiza amasiyana mosiyanasiyana kapena aloyi ali ndi kuchuluka kwambiri, kuwotcherera kozizira kumatha kuchitika mosavuta pazikhazikiko zomwezo. Kwa tinplate yokhala ndi kulemera kwakukulu kwa malata, mipata ya weld nugget yomwe imapezedwa ndi kuwotcherera komweko ndi yaying'ono poyerekeza ndi kulemera kwa malata otsika, kotero kuwotcherera kwabwino kumafuna kuchepetsa liwiro la kuwotcherera. Kuonjezera apo, ngati kuwotcherera kwamakono kuli kwakukulu, malata amatha kulowa m'malire a njere zachitsulo panthawi yosungunuka, zomwe zingathe kuchititsa dzimbiri la intergranular m'zitini zina.
2. MakulidweKukhuthala kwa tinplate kumakhudza kusintha kwa magawo owotcherera, makamaka pamakina owotcherera othamanga kwambiri. Pamene makulidwe a tinplate akuchulukirachulukira, kuchuluka kwa kuwotcherera komwe kumafunikira kumawonjezeka, ndipo malire apamwamba ndi otsika a zinthu zowotcherera amachepetsa ndi makulidwe akuwonjezeka.
3. Kuuma Kuyika kwa kuwotcherera kwa magetsi kumakhudzana ndi kuuma kwa tinplate. Pamene kuuma ukuwonjezeka, kuwotcherera panopa ayenera kuchepetsedwa moyenerera.Pansi mikhalidwe kuwotcherera anapereka, kusiyana tinplate makulidwe ndi kuuma m'magulu yachibadwa sizimakhudza kuwotcherera. Komabe, ngati makulidwe ndi kulimba kumasiyana kwambiri mumtanda womwewo, zingayambitse kusakhazikika kwa kuwotcherera, zomwe zimatsogolera ku kuwotcherera kuzizira kapena nkhani zowotcherera. Mwachitsanzo, pansi pa kukakamizidwa, ngati kuuma kwa tinplate kumawonjezeka mopitirira muyeso, kukana kukhudzana kwapamwamba pakati pa mbale ziwiri kumawonjezeka, zomwe zimafuna kuchepetsa kuwotcherera panopa.
4. Base Steel QualityPamene chitsulo choyambira chili ndi mpweya wambiri wa carbon, kuwotcherera panopa kumafunika kuwonjezeka. Kuonjezera apo, ngati pali zowonjezera zambiri muzitsulo zoyambira, kukana kumawonjezeka panthawi yowotcherera, kumayambitsa mosavuta spatter.Mwachidule, popanga mitundu yosiyanasiyana ya zitini zopanda kanthu kapena kusintha mtundu wa tinplate, mikhalidwe yatsopano yowotcherera iyenera kubwezeretsedwanso.

Konzekerani kukhazikitsa chingwe chatsopano komanso chotsika mtengo?
A: Chifukwa tili ndi ukadaulo wotsogola wopereka makina abwino kwambiri a chitini chodabwitsa.
A: Ndikosavuta kwambiri kuti wogula abwere kufakitale yathu kuti adzatenge makina chifukwa zinthu zathu zonse sizifunikira satifiketi yoyendera zinthu ndipo zimakhala zosavuta kutumiza kunja.
A: Inde! Titha kupereka zida zaulere zovala mwachangu kwa chaka chimodzi, ingotsimikizani kugwiritsa ntchito makina athu ndipo iwowo ndi olimba kwambiri.
