Ku landzelela ntshamiseko wa nhluvukiso wa xihatla wa vuhumelerisi bya xiyimo xa le henhla bya strip continuous rolling na nhluvukiso wa thekinoloji ya gezi yo welda na ku kambela, ku antswisiwa loku yaka emahlweni ka khwalithi ya welding, tinxaka ta 316L stainless steel tiphayiphi ta ti indasitiri leti weldiweke na tona ta tlakuka, naswona yi sivele nsimbi yo ka yi nga tshwukanga eka tiindasitiri to tala. Rhunga chubu. Eka maendlelo ya vuhumelerisi bya tiphayiphi leti weldiweke, ku tiyisisiwa ka weld kunga vuriwa kuva kuri xiphiqo xa nkoka swinene.
Ku tlakuka loku tlulaka mpimo ka weld seam ka 316L stainless steel industrial welded pipe yi na makhombo yo tala lama fihliweke, hi ndlela leyi landzelaka:
(1) Ku pandzeka ka ntshikelelo wa ntshikelelo ku tala ku humelela eka weld toe .
Xilotlelo xa ntshikelelo wa nhlonge ya butt xi vumbiwa hi ku tlakuka ka welding, naswona ntshikelelo wa in-situ eka weld toe ya nhlonge ya butt wukulu swinene.
Tidimenxini ta xikombiso xa ntshikelelo i ku tlakuka ka weld h, angle ya ku hlangana θ eka weld toe na corner semi-warp r. Ku tlakuka ka ku tlakuka ka welding H swi engetela angle θ, naswona ku hunguteka ka ntikelo swi ta engetela stress index.
Loko ku tiyisisiwa lokukulu ka weld, xiyimo xa ntshikelelo xiva xikulu swinene, kambe matimba ya compressive ya butt welding yata hunguteka. Endzhaku ko welda, flatten ku leha loku tlulaka mpimo, loko kuri e henhla kutlula butt weld, hunguta ntshikelelo. Minkarhi yin’wana swinga engetela matimba ya compressive ya butt welding. Weld yale handle yina vukulu lebyi saleke, leswinga ta veka xivumbeko xa chubu ekhombyeni endzhaku ka ku andzisiwa ka ntshikelelo.
Loko phayiphi yo kongoma ya arc welded yi andlariwile ehansi ka ntshikelelo, phayiphi ya nsimbi leyi nga riki na swirhabyani yi phutseriwile hi ku ya hi swivumbeko swa le handle swa xiphemu xa le handle xa ximatsi ni xa xinene leswi nga ni rirhangu leri fanaka ra le ndzeni naswona ku nga ri na swihlawulekisi swa ku andlala ka phayiphi ya nsimbi. Hikokwalaho, loko ku tiyisisiwa ka weld kuri kukulu swinene, loko diameter yi andlariwile, shear stress leyi tekiwaka hi weld yiva na ntolovelo wa 'makumu yo kongoma lawa yantsongo' eka matlhelo hamambirhi ya weld leyikulu.
Kambe ntokoto wa ntirho wu kombisile leswaku loko ku tiyisisiwa ka weld ya le handle ku ri na manipulated eka 2mm kumbe ehansi, a swi olovi ku va na 'maendlelo lamatsongo yo kongoma' loko ntshikelelo wu andlariwile. Muxaka wa phayiphi a wu olovi ku onhaka. Leswi swivangiwa hikuva ku tiyisisiwa ka weld yale handle i kutsongo, naswona shear stress leyi rhwariwaka hi butt weld na yona i yitsongo. Loko muxaka lowu wa ntshikelelo wa shear wuri endzeni ka ndzhawu ya ductile deformation, endzhaku ko rhurhisa, ku tiya ku endliwa, naswona phayiphi ya mati yita tlhelela eka ntolovelo.
(2) Xirhendzevutani xa le ndzeni xa weld xi na ku leha lokukulu loku saleke, leswi engetelaka ku onhaka ka matimba na eneji ya switirhisiwa swa vutleketli.
Loko vuandlalo byale handle bya arc welded pipe kuva byi fambisiwa byi nga pfanganisiwanga na anti-corrosion solution, welding seam yina vukulu lebyi saleke, naswona ku lwisana ka frictional eka switirhisiwa swa swofamba na swona swiri swikulu, leswinga ta engetela ku tirhisiwa ka eneji ya phayiphi ya swofamba.
(3) Ku tiya ka le handle ka ku welda i kukulu, leswi nga riki swinene ku sivela ku bola.
Loko lapi ra nghilazi ra epoxy resin laminated ri tirhisiwa eka anti-corrosion hi nkarhi wa ntirho, ku tlakuka loku engetelekeke ka weld seam ya le handle swi ta endla leswaku swi tika ku tshikilela hi ku tiya eka weld toe. Ku engetela kwalano, loko welding seam yiri e henhla naswona anti-corrosion layer yifanele kuva yiri e henhla, vukulu bya standard anti-corrosion layer byi hlayeriwa kuya hiku hela ka weld seam, leswi engetelaka ntsengo wa anti-corrosion.
Loko ku pimanisiwa na switirhisiwa swa le ndzeni swa xikhamba xa le ndzeni xa switirhisiwa swo susa weld, . Hangao Tech (Seko Machinery)'s . Switirhisiwa swo phaphamala swa le ndzeni leswi kufumelaka hi moya swi na swirhumbana switsongo eka rirhangu ra le ndzeni ra phayiphi ya nsimbi leyi nga riki na swilo swo bola. Nsinya wa yona wa nawu wa ntirho iku tirhisa mandrel leyi akiweke endzeni ku tirhisana na rolling die ku endla repeated rolling 30 times/min eka inner weld seam, leswaku weld seam na base metal swi hlanganisiwa swinene naswona ntshikelelo wuhunguteka.
Loko u ri na swiphiqo leswi fanaka, hi kombela u vulavurisana. Hi tsakile swinene ku ku hlamula.
