Makanema khumi owotcherera, XINFA iwonetsa njira khumi zowotcherera wamba, makanema ojambula mwanzeru, tiyeni tiphunzire limodzi!
1. Electrode arc kuwotcherera
Electrode arc welding ndi imodzi mwamaluso ofunikira kwambiri omwe ma welder amawadziwa bwino. Ngati luso silili bwino m'malo, padzakhala zolakwika zosiyanasiyana mumsoko wowotcherera, monga momwe tawonetsera muvidiyo yophunzitsa yotsatirayi.
2.Submerged arc kuwotcherera
Kuwotcherera kwa arc ndi njira yowotcherera yomwe imagwiritsa ntchito arc ngati gwero la kutentha. Chifukwa cha kulowa kwakuya kwa kuwotcherera kwa arc pansi pamadzi, zokolola ndi kuwotcherera kwabwino ndi zabwino: chifukwa cha chitetezo cha slag, chitsulo chosungunula sichimakhudzana ndi mpweya, ndipo kuchuluka kwa ntchito yamakina ndipamwamba, kotero ndikoyenera. zowotcherera zowotcherera zazitali za mbale zapakatikati ndi zokhuthala.
3.Argon kuwotcherera arc
XINFA ikugawana nanu njira zingapo zopewera kuwotcherera argon arc:
(1) Singano ya tungsten iyenera kunoledwa pafupipafupi. Ngati ili yosamveka, yapanoyo sidzakhazikika komanso kuphuka.
(2) Ngati mtunda wa pakati pa singano ya tungsten ndi msoko wowotcherera uli pafupi, umamatirirana, ngati uli kutali, kuwala kwa arc kumatulutsa maluwa, ndipo ikaphuka, idzawotcha yakuda, singano ya tungsten idzasanduka dazi. , ndipo ma radiation kwa iwo okha ndi amphamvu. Ndi bwino kukhala pafupi.
(3) Kuwongolera kwa switch ndi luso, makamaka pakuwotcherera mbale zoonda, zomwe zimatha kudina ndikudina. Awa si makina owotcherera okha omwe amangoyenda okha komanso kudyetsa waya.
(4) Kudyetsa waya kumakhudza dzanja. Waya wowotcherera wapamwamba kwambiri amadulidwa kuchokera pa bolodi la 304 ndi makina ometa. Osagula m'mitolo. Zachidziwikire, mutha kupeza zabwino m'malo ogulitsa.
(5) Yesetsani kugwira ntchito pansi pa mpweya wabwino, wokhala ndi magolovesi achikopa, zovala, ndi chigoba chodzidzimutsa.
(6) Mutu wa ceramic wa nyali yowotcherera uyenera kutetezedwa ku kuwala kwa arc, makamaka, mchira wa tochi wowotcherera uyenera kukhala pafupi kwambiri ndi nkhope yanu.
(7) Ngati mutha kukhala ndi chidziwitso komanso kusinkhasinkha za kutentha, kukula, ndi kusintha kwa dziwe losungunuka, ndinu katswiri wamkulu.
(8) Yesani kugwiritsa ntchito singano za tungsten zachikasu kapena zoyera, zomwe zimafuna luso lapamwamba.
4.Kuwotcherera gasi
Kuwotcherera mpweya (dzina lonse: mpweya mafuta kuwotcherera mpweya, chidule: OFW) ndi ntchito lawi kutenthetsa zitsulo ndi kuwotcherera waya pa olowa workpiece zitsulo kusungunuka kuti akwaniritse cholinga kuwotcherera. Mipweya yoyaka yomwe imagwiritsidwa ntchito nthawi zambiri ndi acetylene, mafuta amafuta a liquefied ndi haidrojeni, ndi zina zotere, ndipo mpweya wothandiza kuyaka womwe amagwiritsidwa ntchito kwambiri ndi mpweya.
5.Kuwotcherera kwa laser
Kuwotcherera kwa laser ndi njira yabwino komanso yolondola yowotcherera yomwe imagwiritsa ntchito mtanda wa laser wamphamvu kwambiri ngati gwero la kutentha. Kuwotcherera laser ndi chimodzi mwazinthu zofunika kwambiri pakugwiritsa ntchito luso laukadaulo la laser. M'zaka za m'ma 1970, ankagwiritsidwa ntchito kwambiri powotcherera zipangizo zokhala ndi mipanda yopyapyala komanso kuwotcherera otsika kwambiri. The kuwotcherera ndondomeko ndi kutentha conduction, ndiko kuti, ndi laser cheza Kutentha pamwamba pa workpiece, ndi kutentha pamwamba diffused mpaka mkati kudzera kutentha conduction. Ndi kulamulira m'lifupi, mphamvu, nsonga mphamvu ndi kubwerezabwereza pafupipafupi kwa laser zimachitika ndi magawo ena kusungunula workpiece ndi kupanga yeniyeni dziwe losungunuka.
6. Carbon dioxide shield kuwotcherera
Owotcherera ena ambuye amaganiza kuti kuwotcherera kwa carbon dioxide ndikosavuta, chifukwa ndikosavuta kugwiritsa ntchito ndi kuphunzira. Nthawi zambiri, ngati novice amene sanakumanepo ndi kuwotcherera, ngati mbuye kumuphunzitsa kwa maola awiri kapena atatu, kwenikweni losavuta udindo kuwotcherera akhoza opareshoni.
Pali mfundo zingapo zofunika pophunzira mpweya woipa wotetezedwa kuwotcherera: manja okhazikika, chosinthika panopa ndi voteji, controllable kuwotcherera liwiro, manja, amene angathe kudziwa mwa kuonera mavidiyo ambiri, ndiyeno adziwa zinayendera kuwotcherera, amene angathe makamaka kusamalira oposa theka la ntchito anapempha.
7.Friction kuwotcherera
Kuwotcherera kwa friction kumatanthawuza njira yowotcherera pogwiritsa ntchito kutentha komwe kumapangidwa ndi kukangana kwa malo okhudzana ndi malo ogwirira ntchito monga gwero la kutentha kumapangitsa kuti workpiece iwonongeke ndi pulasitiki.
Pansi pa kukakamizidwa, pansi pa kukakamiza kosalekeza kapena kowonjezereka ndi torque, kusuntha kwachibale pakati pa malo omwe amawotchera kukhudzana ndi mapeto kumagwiritsidwa ntchito popanga kutentha kwa kutentha ndi kutentha kwa pulasitiki pamwamba pa mikangano ndi madera ozungulira, kotero kuti kutentha kwa kutentha kwa pulasitiki kumapangitsa kuti pakhale kutentha. madera ozungulira amakwera Kutentha kwapafupi koma nthawi zambiri kumakhala kotsika kuposa malo osungunuka, kukana kwa ma deformation kumachepetsedwa, pulasitiki imapangidwa bwino, ndipo filimu ya oxide pa mawonekedwe imasweka. Njira yowotcherera yolimba yomwe imakwaniritsa kuwotcherera.
Kuwotcherera kwa friction nthawi zambiri kumakhala ndi njira zinayi izi: (1) kutembenuka kwa mphamvu yamakina kukhala mphamvu yotentha; (2) pulasitiki mapindikidwe zipangizo; (3) kukakamiza kukakamiza pansi pa thermoplasticity; (4) intermolecular diffusion ndi recrystallization.
8.Ultrasonic kuwotcherera
Akupanga kuwotcherera ndi kugwiritsa ntchito mafunde othamanga kwambiri kuti atumize pamalo azinthu ziwiri kuti ziwotchedwe. Pakanikizidwa, pamwamba pa zinthu ziwirizi amasudzulana kuti apange kuphatikizika pakati pa zigawo za maselo. Zigawo zikuluzikulu za akupanga kuwotcherera dongosolo monga akupanga jenereta / transducer / nyanga / kuwotcherera mutu katatu / nkhungu ndi chimango.
9.Soldering
Brazing ndikugwiritsa ntchito chitsulo chokhala ndi malo otsika osungunuka kuposa zitsulo zoyambira monga solder, kutenthetsa weldment ndi solder ku kutentha kwakukulu kuposa kusungunuka kwa solder ndi kutsika kuposa kutentha kwachitsulo chosungunuka, gwiritsani ntchito madzi. solder kunyowetsa zitsulo m'munsi, mudzaze kusiyana pakati pa mfundo ndi Njira interdiffusion ndi m'munsi zitsulo kuzindikira kugwirizana weldment. The brazing deformation ndi yaying'ono, ndipo cholumikizira chimakhala chosalala komanso chokongola. Ndi oyenera kuwotcherera mwatsatanetsatane, zovuta ndi zigawo zikuluzikulu zopangidwa ndi zipangizo zosiyanasiyana, monga mbale zisa kapangidwe, masamba turbine, zida zolimba aloyi ndi kusindikizidwa matabwa dera. Kutengera kutentha kwa kuwotcherera, brazing imatha kugawidwa m'magulu awiri. Ngati kutentha kwa kuwotcherera kuli kochepa kuposa 450 ° C, kumatchedwa soft soldering, ndipo ngati kuli pamwamba kuposa 450 ° C, kumatchedwa hard brazing.
