1. Molao-motheo oa bohlokoa oa ho tjheseletsa arc ka li-electrode
Bakeng sa ho kenya le ho tjheseletsa liphaephe tseo bophara ba tsona bo seng boholo haholo (joalo ka tlase ho 610mm) le bolelele ba pipeline ha bo telele haholo (joalo ka tlase ho 100km), ho tjheseletsa arc ea electrode ho lokela ho nkoa e le khetho ea pele.Tabeng ena, electrode arc welding ke mokhoa o nang le chelete e ngata ka ho fetisisa oa Welding.
Ha e bapisoa le tjheseletso e iketsang, e hloka thepa le basebetsi ba fokolang, ditjeho tse tlase tsa ho e lokisa, le sehlopha sa kaho se seng se butswe ho feta.
Electrode arc welding e 'nile ea sebelisoa bakeng sa ho kenya le ho tjheseletsa ka lilemo tse fetang 50.Li-electrode tse fapaneng le mekhoa e fapaneng ea ts'ebetso li batla li holile tsebong ho tsa theknoloji.Palo e kholo ea data, tlhahlobo ea boleng e bonolo.
Ha e le hantle, bakeng sa ho tjheseletsa ha liphaephe tsa tšepe tse phahameng-matla, tlhokomelo e boetse e lokela ho lefshoa ho khethoa le ho laola lithupa tsa welding le mehato ea ts'ebetso.Ha welding e latela mokhoa o tloaelehileng oa lipeipi AP1STD1104-2005 "Welding ea liphaephe le lisebelisoa tse amanang le tsona), sebelisa li-welders tse koetlisitsoeng tse koetlisitsoeng le ho lekoa.Ha tlhahlobo ea radiographic ea 100% e etsoa, hoa khoneha ho laola sekhahla sa tokiso ea li-welds tsohle tse ka tlase ho 3%.
Ka lebaka la litšenyehelo tse tlase le tlhokomelo.Ha e kopantsoe le boleng bo tiisitsoeng, ho cheselletsa li-electrode arc e bile khetho ea pele ea likonteraka tse ngata tsa morero nakong e fetileng.
2. Ka tlas'a metsi arc jarolla ka ho iketsa tjheseletsa molao-motheo oa bohlokoa
Joalokaha ho boletsoe pejana, ho tjheseletsa ha liphaephe ka ho qoelisoa ka metsing ho etsoa liteisheneng tsa ho tjheseletsa liphaephe tse etselitsoeng liphaephe ka ho khetheha.Haeba liphaephe tse peli li cheselitsoe haufi le sebaka sa marang-rang (habeli pipe welding), palo ea li-welds moleng o ka sehloohong e ka fokotsoa ka 40% ho ea ho 50%, e leng ho khutsufatsang haholo potoloho ea ho beha.
Ts'ebetso e phahameng le boleng bo phahameng ba ho tjheseletsa ka ho iketsa ha arc bakeng sa ho kenya tjheseletsa ho hlakile, haholo-holo bakeng sa liphaephe tse nang le bophara bo boholo (ka holimo ho 406mm) le botenya ba lebota bo fetang 9.5mm, ha sebaka sa ho beha se le telele, ka mabaka a moruo, Hangata, mokhoa oa ho tjheseletsa arc ka ho iketsa ka metsing ho nkuwa pele.
Leha ho le joalo, khetho ea khetho e le 'ngoe ke hore na tsela ea ho tsamaisa lipeipi tse peli e ka khoneha, hore na maemo a litsela a e lumella, le hore na ho na le maemo a ho tsamaisa lipeipi tse peli nako e telele ho feta 25m.Ho seng joalo, tšebeliso ea li-arc welding e ke ke ea e-ba le moelelo.
Ka hona, bakeng sa liphaephe tse telele tse nang le bophara bo fetang 406mm le botenya bo boholo ba lerako, ha ho se na mathata a lipalangoang le maemo a litsela, mokhoa oa ho tjheseletsa liphaephe tse peli kapa tse tharo tse nang le li-arc welding ke khetho e ntle ka ho fetisisa bakeng sa likonteraka tsa morero.
3.Flux cored teratasemi-automatic welding molao-motheo oa bohlokoa
Ha e kopantsoe le li-electrode arc welding, flux cored wire semi-automatic welding ke mokhoa o motle oa ho tjheseletsa oa ho tlatsa welding le ho koahela liphaephe tsa tšepe tse bophara bo boholo le tse teteaneng.
Morero o ka sehloohong ke ho fetola ts'ebetso ea ho tjheseletsa ha nakoana hore e be mokhoa o tsoelang pele oa tlhahiso, 'me sekhahla sa tjheseletsa se phahame ho feta sa electrode arc welding, terata ea welding e qhibiliha ka potlako,' me katleho ea tlhahiso e ka ba makhetlo a 3 ho isa ho a 5 ho feta arc ea electrode. welding, kahoo katleho ea tlhahiso e phahame.
Hajoale, ho tjheseletsa ha semi-automatic wire e sirelelitsoeng ka boyona e sebelisoa haholo ho cheselletsa liphaephe ka lebaka la ho hanyetsa moea o matla, litaba tse tlase tsa haedrojene ha li chesehela, le ts'ebetso e phahameng.Ke mokhoa o ratoang oa kaho ea lipeipi naheng ea heso.
4. Molao-motheo oa bohlokoa oa MIG othomathike welding
Bakeng sa liphaephe tsa sebaka se selelele tse bophara bo fetang 710mm le botenya bo boholo ba lerako, e le ho fumana katleho e phahameng ea kaho le boleng bo phahameng, MIGA e atisa ho nkoa e le ea pele.
Mokhoa ona o 'nile oa sebelisoa ka lilemo tse 25,' me o 'nile oa ananeloa ka bophara bakeng sa lipeipi tse bophara bo boholo lefatšeng ka bophara, ho kenyelletsa le lihlopha tsa lipeipi tse lebōpong la leoatle le ka tlas'a metsi,' me ka kakaretso e nkoa e le ea bohlokoa Canada, Europe, Middle East le linaheng tse ling le libaka.
Lebaka la bohlokoa le etsang hore mokhoa ona o sebelisoe haholo ke hore boleng ba ho kenya le ho tjheseletsa bo ka tiisetsoa, haholo-holo ha ho tjheseletsa liphaephe tse matla haholo.
Ka lebaka la dikahare tlase haeterojene tsa mokhoa ona tjheseletsa, le ditlhoko tse batlang e le thata ka ho hlophisoa le ho etsa terata tjheseletsa, haeba toughness tlhokahalo e phahameng kapa phaepe e sebelisoa ho tsamaisa mecha ea litaba asiti, tjheseletsa liphaephe tšepe phahameng-sehlopheng sena. mokhoa ka fumana tsitsitseng tjheseletsa boleng.
Ke habohlokoa ho hlokomela hore ha ho bapisoa le li-electrode arc welding, matsete a tsamaiso ea tšepe ea arc e kholo, 'me litlhoko tsa lisebelisoa le basebetsi li phahame.Tlhokomelo e tsoetseng pele e hlokahalang e tlameha ho nkoa, 'me lisebelisoa le khase e tsoakiloeng tse finyellang litlhoko tsa bohloeki li tlameha ho nkoa.phepelo.
