raye-rayen walda guda goma, XINFA za ta gabatar da hanyoyin walda guda goma na gama-gari, raye-rayen raye-raye, mu koyi tare!
1.Electrode baka walda
Electrode arc walda yana ɗaya daga cikin manyan ƙwarewar da masu walda suka ƙware. Idan ba a ƙware a wurin ba, za a sami lahani iri-iri a cikin ɗinkin da aka yi masa walda, kamar yadda aka nuna a cikin bidiyon koyarwa na gaba.
2.Baka walda
Waldawar baka mai nutsewa hanya ce ta walda wacce ke amfani da baka a matsayin tushen zafi. Saboda zurfin shigar azzakari cikin farji na submerged arc waldi, da yawan aiki da waldi quality ne mai kyau: saboda kariyar slag, narkakkar karfe ba ya zuwa cikin lamba tare da iska, da kuma mataki na mechanized aiki yana da girma, don haka ya dace. domin walda dogon welds na matsakaici da lokacin farin ciki farantin Tsarin.
3. Argon baka walda
XINFA tana ba ku wasu ƴan matakan kariya don waldawar argon:
(1) Ya kamata a kaifi allurar tungsten akai-akai. Idan ya bushe, na yanzu ba zai maida hankali ba kuma yayi fure.
(2) Idan tazarar da ke tsakanin allurar tungsten da takin walda ta kusa, za ta manne wuri guda, idan ta yi nisa, hasken baka zai yi fure, da zarar ya yi fure sai ya kone baki, allurar tungsten za ta zama m. , kuma radiation ga kanta ma yana da ƙarfi. Zai fi kyau ku kasance kusa.
(3) Sarrafa maɓalli fasaha ce, musamman don walƙiya na bakin ciki, wanda ba za a iya dannawa kawai ba. Wannan ba injin walda ba ne ta atomatik tare da motsi ta atomatik da ciyarwar waya ta atomatik.
(4) Don ciyar da waya, yana da jin daɗin hannu. An yanke igiyar walda mai girma daga allon 304 tare da na'ura mai yanke. Kar a siya shi a daure. Tabbas, zaku iya samun masu kyau a wuraren siyarwa.
(5) Yi ƙoƙarin yin aiki a ƙarƙashin yanayin iska, sanye da safofin hannu na fata, tufafi, da abin rufe fuska ta atomatik.
(6) Shugaban yumbu na fitilar walda ya kamata a kiyaye shi daga hasken baka, musamman, wutsiya na walda ya kamata ya kasance kusa da fuskarka.
(7) Idan za ku iya samun fahimta da hunch game da zafin jiki, girman, da canza aikin narkakken tafkin, kai babban ƙwararren masani ne.
(8) Yi ƙoƙarin amfani da alluran tungsten mai launin rawaya ko fari, wanda ke buƙatar ƙwararrun ƙwararru.
4. Walda Gas
Walda iskar gas (cikakken suna: iskar oxygen gas waldi, gajarta: OFW) shine amfani da harshen wuta don dumama karfe da walda waya a haɗin gwiwar karfen workpiece don narke shi don cimma manufar walda. Gas masu ƙonewa da aka fi amfani da su sune acetylene, iskar gas mai ruwa da hydrogen, da sauransu, kuma iskar gas ɗin da ake amfani da ita ta hanyar konewa shine oxygen.
5. Laser walda
Laser walda wata ingantacciyar hanya ce ta walƙiya wacce ke amfani da katako mai ƙarfi da ƙarfi a matsayin tushen zafi. Laser walda yana daya daga cikin muhimman al'amurran da aikace-aikace na Laser kayan sarrafa fasahar. A cikin 1970s, an fi amfani da shi don walda kayan katangar bango da walƙiya mara sauri. Hanyar walda ita ce tafiyar da zafi, wato, radiation na Laser yana dumama saman kayan aikin, kuma zafin saman yana yaduwa zuwa ciki ta hanyar tafiyar da zafi. Ta hanyar sarrafa faɗin, kuzari, ƙarfin kololuwa da maimaitawa na bugun bugun laser da sauran sigogi don narke aikin aikin da samar da takamaiman narkakken tafkin.
6. Carbon dioxide kariya waldi
Wasu ƙwararrun ƙwararrun ƙwararrun masanan suna ganin cewa walda mai kariya ta carbon dioxide ita ce mafi sauƙi, saboda ita ce mafi sauƙi don amfani da koyo. Gabaɗaya, idan novice wanda bai taɓa hulɗa da walda ba, idan maigida ya koya masa sa'o'i biyu ko uku, ana iya sarrafa walda mai sauƙi.
Akwai da yawa key maki a cikin koyon carbon dioxide garkuwa waldi: tsayayye hannaye, daidaitacce halin yanzu da ƙarfin lantarki, controllable waldi gudun, ishãra, wanda za a iya ƙware da kallon more videos, sa'an nan Master waldi jerin, wanda zai iya m rike fiye da rabin. aikin ya nema.
7.Friction waldi
Welding juzu'i yana nufin hanyar walda ta amfani da zafin da aka haifar ta hanyar gogayya ta fuskar lamba na workpiece a matsayin tushen zafi don haifar da nakasar filastik a ƙarƙashin matsin lamba.
A karkashin aiki na matsa lamba, a karkashin mataki na akai-akai ko karuwa matsa lamba da karfin juyi, da zumunta motsi tsakanin waldi lamba karshen saman da ake amfani da su samar da gogayya zafi da filastik nakasar zafi a kan gogayya surface da kewaye, sabõda haka, da yawan zafin jiki na yankunan da ke kewaye da su sun tashi zuwa A cikin kewayon zafin jiki kusa da amma gabaɗaya ƙasa da ma'anar narkewa, ƙarancin juriya na kayan yana raguwa, an inganta filastik, kuma fim ɗin oxide akan mahaɗin ya karye. A m-jihar waldi Hanyar cewa cimma waldi.
Waldawar juzu'i yakan ƙunshi matakai huɗu masu zuwa: (1) jujjuya makamashin inji zuwa makamashin thermal; (2) nakasar filastik na kayan; (3) ƙirƙira matsa lamba a ƙarƙashin thermoplasticity; (4) intermolecular diffusion da recrystallization.
8.Ultrasonic waldi
Waldawar Ultrasonic shine amfani da raƙuman girgiza mai ƙarfi don watsawa saman abubuwa biyu da za a yi walda. Ƙarƙashin matsi, ana shafa saman abubuwan biyu da juna don samar da fusion tsakanin sassan kwayoyin halitta. Babban abubuwan da aka gyara na wani ultrasonic waldi tsarin sun hada da ultrasonic janareta / transducer / ƙaho / waldi shugaban sau uku / mold da firam.
9.Siyarwa
Brazing shine a yi amfani da kayan ƙarfe tare da ƙaramin narkewa fiye da ƙarfe na tushe azaman mai siyarwa, dumama walda da siyar zuwa yanayin zafi sama da wurin narkewar siyar kuma ƙasa da yanayin narkewar ƙarfen tushe, yi amfani da ruwa. solder to jika tushe karfe, cika rata tsakanin gidajen abinci da kuma Hanyar interdiffusion tare da tushe karfe gane dangane da walda. Nakasar brazing ƙananan ne, kuma haɗin gwiwa yana da santsi da kyau. Ya dace da daidaiton walda, hadaddun da abubuwan da aka haɗa da kayan daban-daban, kamar faranti tsarin saƙar zuma, ruwan wukake, kayan aikin gami da bugu da allunan kewayawa. Dangane da zafin walda, brazing za a iya raba kashi biyu. Idan zafin dumama walda yana ƙasa da 450 ° C, ana kiran shi mai laushi mai laushi, kuma idan ya fi 450 ° C, ana kiran shi hard brazing.
