Eka ntirho wa tiphayiphi na tilayini, yin’wana ya tindlela letinene to endla ntirho i ku xava muchini wo welda tiphayiphi hi ku tisungulela .Swipfuno swaku tirhisa muxaka lowu wa switirhisiwa swo welda swikatsa: kuhunguteka ka matimba ya vanhu lawa ya lavekaka eka endlelo, ku tirha kahle swinene, ku engeteleriwa ka rivilo xikan’we na vuhumelerisi lebyikulu.Hi mimpfuno leyi, a swi hlamarisi leswi vaendli va michini yo welda tiphayiphi hi ku tisungulela va yaka emahlweni va vona ku tlakuka loku nga cincekiki ka ku xavisiwa.Nakambe a swi hlamarisi leswi ha yini mixaka leyi ya michini yi ya emahlweni yi tiphina hi xiphemu xa makete lexi tiyeke swonghasi.
Vaendli va tiphayiphi na ti line vafanele kuva na switirhisiwa swa vona leswi endliweke kusuka eka switirhisiwa leswi endlaka leswaku va endla swiphemu swo olova, leswi ringanaka leswingana slag yitsongo.Handle ka switirhisiwa leswi faneleke, nchumu lowu hetiweke wu ta va wu nga ringani naswona wu ta va ni muvala wo biha, leswi haswimbirhi swi endlaka leswaku ku va ni swihoxo leswi durhaka.Ku hlawula leswinene muendli wa muchini wo welda tiphayiphi hi ku tisungulela u vula leswaku khamphani ya swi twisisa leswaku khwalithi ya ku welda yi fanele ku va ya xiyimo xa le henhla swinene.Tikhamphani leti ti endla leswaku switirhisiwa swa tona swa switirhisiwa swo welda swi kumeka hi tinxaka to hambana hambana na tinxaka to hambana ta ti alloys.
Muxaka lowu dumeke wa muchini wo welda wa otomatiki lowu endliwaka hi le henhla muendli wa muchini wo welda tiphayiphi hi ku tisungulela u vuriwa CIG welding (kumbe Cigarette Steel).Loko switirhisiwa na standard tubing, muxaka lowu wa switirhisiwa wunga endla tiphayiphi to tiya, to tiya leti tiyeke eka ku bola.Tiphayiphi leti, loko ti tiyisiwa hi nsimbi ya alloy, na tona ti endla vuhlanganisi lebyi tiyeke swinene.Muxaka lowu wa welding wutala kutirhisiwa ku hlanganisa makumu ya ti insulated piping, kambe wunga tlhela wutirhisiwa ku hlanganisa endzeni ka ti metallic tubes, kumbe ku hlanganisa swiphemu swa insulated piping leswi kumekaka ekule swinene.Muxaka lowu wa muchini wu tirhisa kuhisa ku hlanganisa makumu mambirhi ya tubing.
Muxaka wun’wana lowu dumeke wa muchini wo welda wa otomatiki wu vuriwa muchini wo welda wa carbon steel arc.Michini leyi yi tirhisa nsimbi leyi tengeke ya khaboni (kumbe nsimbi leyi hlanganisiweke) ematshan’weni ya nsimbi ya ndhavuko, leyi nyikaka ndhawu leyi ringanaka, leyi rhetaka loko yi hlanganisiwa.Weld leyi muchini lowu wu yi tumbuluxaka yi tiyile naswona yi tshamisekile ku tlula ti weld leti unga ti humesaka hiku tirhisa ti tubing ta ntolovelo.Muxaka lowu wa muchini wo welda hi ntolovelo wu humesa weld ya khwalithi yale henhla swinene kutlula leyi humelerisiwaka kusuka eka muchini wo welda wa CIG.
Loko u lava phayiphi leyi nga ta tirhisiwa eka switirhisiwa swo hambana hambana swo hambana, kutani swa antswa ku languta eka muendli loyi a nyikaka layini ya switirhisiwa leswi endliweke kusuka eka nkatsakanyo wa switirhisiwa leswimbirhi swo endla tiphayiphi.Loko phayiphi yi endliwa kusuka eka nsimbi ya khaboni, kuna vuswikoti bya leswaku phayiphi yita khwaxa hiku olova.Kambe loko nkatsakanyo lowu wu vumbiwa hi nsimbi ya alloy, vuswikoti byo khwaxa kahle-kahle a byi kona.Hikwalaho ka leswi, ku muendli wa muchini wo welda tiphayiphi hi ku tisungulela u ta tala ku nyikela layini ya swilo leswi nga ni swiaki leswi haswimbirhi leswi hlanganisiweke.Leswi swita nyika vaxavi va wena vuswikoti byo welda tiphayiphi letinga na rust naswona tinga tiya.
Loko u lava muphakeri wa muchini wo welda tiphayiphi, i swa nkoka ku twisisa leswi endlaka leswaku khamphani yin’wana yi tlakuka eka yin’wana.Loko u kuma khamphani leyi nyikaka ti CIG na ti automatic pipe welders, uta switiva leswaku u kuma muchini wotala lowu kotaka kuku nyika mbuyelo wa kahle swinene.U ta tlhela u swi tiva leswaku khampani ya tinyungubyisa hi ntirho wa vona naswona yi nga tshembiwa leswaku yi endla ntirho hi nkarhi.Loko u hlawula ku tirhisa an automatic pipe welding machine , u ta swi tiva leswaku u endle xiboho lexinene.
