Ho sa tsotelehe hore na motsoako oa welding o hokae, ha e le hantle ke pokello ea boiphihlelo ba welding.Bakeng sa li-novices, maemo a bonolo ke boikoetliso ba mantlha, ho qala ka ho potoloha le ho fetela ho maemo a tsitsitseng.
Rotation welding e lumellana le welding e tsitsitseng ka liphaephe.Welding e tsitsitseng e bolela hore lenonyeletso la welding le ke ke la sisinyeha ka mor'a hore sehlopha sa liphaephe se tsamaisane, 'me ho chesoa ho etsoa ho ea ka phetoho ea boemo ba ho tjheseletsa (liphetoho tse rapameng, tse holimo, tse holimo le tse bohareng) nakong ea ts'ebetso ea welding.
Ho potoloha boema-kepe ba tjheseletsa ke ho potoloha boemakepe ba tjheseletsa nakong ya ho tjheseletsa e le hore setjheseletsa se kgone ho etsa welding sebakeng se loketseng (se seng se tshekaletseng, se otlolohileng, ho ya hodimo le tlase).
Ha e le hantle, ho bua feela, motsoako o tsitsitseng oa welding ke seam se cheselitsoeng setšeng, se amanang le phaephe e entsoeng esale pele.
Lenonyeletso le tsitsitseng le bolela hore phala ha e sisinyehe, 'me mochine o cheseletsa o etsa li-welding tse pota-potileng, haholo-holo ha mokhoa oa welding o le holimo, mokhoa oa ho cheselletsa ha o bonolo ho sebetsa, litlhoko tsa tekheniki tsa welder li phahame,' me liphoso li atisa ho ba teng. etsahala.Hangata, kaho e etsoa ka setsing sa liphaephe;
Boema-kepe bo pota-potileng ke phala e ka fetoloang.Boemo ba ho tjheseletsa ha e le hantle ke welding e bataletseng kapa welding e otlolohileng.Ts'ebetso ea welding e bonolo ebile ho na le liphoso tse fokolang.Ha e le hantle e hahiloe fatše kapa fatše.
Nakong ea tlhahlobo ea li-welding, e le ho thibela likou tsohle tse bilikang hore li se khethoe ka mokhoa o sa reroang bakeng sa tlhahlobo, sekhahla sa ho pasa se phahame, 'me karolo e itseng ea likou tse tsitsitseng e tlameha ho hlahlojoa ka mokhoa o sa reroang ho netefatsa boleng ba tjheseletso ea phaephe eohle."Pressure Pipeline Safety Technology Supervision Regulations-Industrial Pipeline" e bolela hore karo-karolelano ea ho lemoha ha li-welding tse tsitsitseng ha ea lokela ho ba ka tlase ho 40%.
Ka kakaretso, re sebelisa kou e tsitsitseng e le kou e sebetsang.Boema-kepe bo sebetsang ke motsoako oa welding o entsoeng esale pele oa phala, 'me karolo ea phala e ka sisinyeha kapa ea potoloha ha phala e entsoe esale pele ka ntle ho sebaka.Boema-kepe bo tsitsitseng ke boema-kepe bo kentsoeng setšeng moo phala e ke keng ea sisinyeha kapa ho potoloha.
Ka tlhaloso ea liphaephe tsa nako e telele, e bitsoa "collision dead end", 'me ho hlokahala hore "100% tlhahlobo ea radiographic e etsoe".The dead end welding angle e rarahane, 'me boleng ba welding ha bo bonolo ho netefatsa.
Li-welds tse tsitsitseng li amana le li-weld tse potolohang.
Lenonyeletso le tjheseletsang le bolela hore setjheseletsa se ka potoloha lenonyeletso la tjheseletsa ho ya ka thato ho ya ka lehlakoreng le letle ka ho fetisisa la ho tjheseletsa ha tjheseletsa nakong ya tjheseletsa e tjheseletsang phala, mme boleng ba tjheseletsa bo batla bo tsitsitse, ka hona, ditjheseletsa di rata mofuta ona wa tjheseletsa. .
Leha ho le joalo, ka lebaka la litlhoko tsa maemo a sebaka sa marang-rang kapa maemo a workpiece ka boeona, lenonyeletso la welding la li-workpieces tse ling li ka lokisoa feela, e leng seo ho thoeng ke selekane se tsitsitseng sa welding.Ha lenonyeletso le tsitsitseng la welding le kentsoe le ho chesetsoa, ho na le lenonyeletso le le leng feela la welding.Mofuta ona oa motsoako oa ho tjheselletsa ho thata ho o tjheseletsa, mme karolo ya tlhahlobo e sa senyeheng e phahame.
Litaelong tse ling tsa kaho ea liphaephe, karolo ea tšibollo e tsitsitseng ea weld e boletsoe ka ho hlaka.Hobane li-angles tsa li-welds tse tsitsitseng li fapane, welding ka letsoho e tla fetoha, 'me boleng ba li-welds bo tla ameha ho isa bohōleng bo itseng.Ka mohlala, li-welds tse tsitsitseng tsa liphaephe tsa tšepe li hloka hore li-welders li etse li-welding tsohle, tse hlokang litlhoko tse phahameng bakeng sa li-welders.Ehlile, mokhoa ona o phahame mme boemo ba tekheniki bo phahame.Motho ea chesehelang hantle ha ho na taba.
Tsamaisong ea kaho, palo ea menyetla e tsitsitseng e lokela ho fokotsoa ka hohle kamoo ho ka khonehang.Ka lehlakoreng le leng, boleng ba welding bo ka laoloa, 'me ka nako e ts'oanang, palo ea menyetla ea ho hlahloba e ka fokotsoa ho fokotsa litšenyehelo.
