Inkatho Welding yensimbi

Iron - okungukuthi, njengoba aziwa, yensimbi ne-carbon ingxubevange. Okuqukethwe yokugcina kufanele ibe ngaphezu amaphesenti amabili. Kuye isimo lapho ingxubevange carbon, ukuhlukanisa grey nomhlophe izinhlobo cast iron. Ngo ifomu kuqala carbon kwenziwa ngendlela graphite, esimweni khulula, inquma machinability zalo ezinhle. Kusukela white cast iron, lesi sici is esimweni eboshiwe, cishe akunakwenzeka ukushisela. Ekuqaleni kwawo-okokusebenza ukukhanya ngombala.

iyona Welding cast iron kanjani? Ake uqale nge yokuthi le nto - hhayi ofanele kakhulu lolu hlobo ukwelashwa. Lapho Welding ke deforms futhi kalula imifantu. Lokhu kungenxa isakhiwo okhethekile carbon e ukwa yayo. Ezinamafutha akahle cast iron, kanye nalabo abaye zabhekana ukuchayeka abezindaba ahlukahlukene ezonakalisayo, ayikwazi ashiselwe. Nokho, lokhu, kukhona izinhlobo enhle ukuthi kukhona grained futhi emihle ukukhanya grey umbala. Welding yensimbi has side effects: mhlophe futhi ngenxa yalokho, okuvela endaweni kokwenza Welding ezimhlophe yensimbi ungqimba okungadingi umboleke ngokwayo ukuze akukho ukwelashwa; Njengoba sekushiwo, lapho kumiswa imifantu; okwandisa voltage ezonini Welding; the weld pool metal kungenzeka ukungena nakwamanye amazwe ngenxa carbon nokutubeka kweqembu kanyekanye-carbon dioxide. Ngakho, le nqubo kubangela eziningi nobunzima. Nokho Welding cast iron isetshenziswa kabanzi ngempela. It has izindlela ezintathu eziyinhloko: abandayo kanye ashisayo lulwimi.

Okokuqala kuyinto ukungabi khona preheating. Welding Cold cast iron is ezenziwe ngensimbi, yensimbi cast futhi esenziwe non-ayoni futhi Alloys electrode. Into esemqoka nalokhu - ukugwema ukushisa okukhulu ezonini ukushisa-abathintekayo. Ngenxa yalesi steel electrode usebenzisa electrode ungqimba wokuqala superposed ubukhulu encane nge okuqukethwe encane ye-carbon, enamathela mncane. Amperage kulesigaba kumele singeqi 90 Amps. izingqimba Okwalandela kuthiwa superposed electrode ka ububanzi mkhulu, luthi alufane kungaba mncane noma obukhulu.

Omunye umthetho obalulekile - emalungeni metallic kudingeke ukuba sisisebenzise kuzo nge iziphazamiso ambalwa ukufudumeza-abathintekayo lokushisa zone ingeqi degrees ayisithupha.

Uma Welding kufanele ukwenziwa izingxenye ezibucayi ke ungasebenzisa idivayisi ekhethekile. Lokhu okuthiwa vvertyshi - izikopelo ekhethekile, okuyinto ezenziwe ngensimbi omnene. inhloso yabo - ukuxhumanisa metal weld nensimbi. Zokushisela wenziwa lokuqala, elibazungezile, bese - ngendlela evamile. Lapho kubalulekile ukushisela iyiphi ekubunjweni ukukhubazeka, emifantwini nezinye amaphuzu nababuthakathaka, ngokuvamile esetshenziselwa electrode eyenziwe Alloys esekelwe nickel noma ithusi. Ukukhuthaza graphitization, they nqanda ukuvela indawo ebanzi amakhorali. Welding yensimbi ekhaya ikakhulu kukhiqizwa indlela abandayo. Lokhu kungase kusetshenziswe kunoma yiziphi izinhlobo electrode eshiwo ngenhla.

Hot yensimbi Welding kuhilela amalahle workpiece phambi ezisebenza ngayo. Le ndlela kunciphe voltage isakhiwo sensimbi. Ukuze indlela lulwimi - is a modified ashisayo. Kuyinto zensimbi graphitization bafudumale jikelele noma wendawo lokushisa ethile. Lezi izindlela ezisetshenziswa ngezindlela ezihlukahlukene.

Uma ufuna ukwenza Welding izingxenye ngabanye wenza cast iron, kuleso simo ukusetshenziswa abandayo Welding indlela. Uma umsebenzi wenziwa ngesikhathi isitshalo, ngezinga ezimbonini, sebenzisa indlela ashisayo.
