welding performance concept ya switirhisiwa swa nsimbi .
Ku welda ka switirhisiwa swa nsimbi swivula vuswikoti bya switirhisiwa swa nsimbi kuva swikuma swihlanganisi swa kahle swinene swa welded ehansi ka swiyimo swokarhi kukatsa na tindlela to welda, switirhisiwa swo welda, swihlawulekisi swa welding, na swivumbeko swa xivumbeko xa welding. Loko nsimbi yi nga kuma weld ya kahle hi ntirho lowu tolovelekeke ni wo olova lowu eka wona . Welding Machine Process , swi tekiwa leswaku nsimbi leyi yina matirhelo ya kahle ya welding. Ku hlanganisiwa ka switirhisiwa swa nsimbi hi ntolovelo swi katsa swiyenge swimbirhi: weldability ya phurosese na ku tirhisiwa ka weldability.
weldability ya phurosese: swivula vuswikoti byo kuma ti welds ta kahle swinene, letinga na swihoxo ehansi ka swiyimo swokarhi swa maendlelo ya welding. Hambiswiritano, a hi nhundzu ya ntumbuluko ya nsimbi, kambe i xikili lexi simekiweke eka ndlela yo karhi yo karhi yo welda na magoza yo karhi ya phurosese lama amukeriweke. Hikokwalaho, process weldability ya switirhisiwa swa nsimbi yi fambelana swinene na maendlelo ya welding.
Use weldability: Yi kombetela eka mpimo lowu nhlangano lowu weldiweke kumbe xivumbeko hinkwaxo xi hlanganaka na matirhelo ya matirhiselo lama boxiweke eka swiyimo swa xithekiniki swa xiendliwa. Matirhelo ya vukorhokeri ya kumiwa hi swiyimo swa ntirho swa xivumbeko xa welded na swilaveko swa xithekiniki leswi vekiweke emahlweni eka dizayini, hi ntolovelo ku katsa na swivumbeko swa michini, ku tiya ka mahiselo ya le hansi, ku lwisana na ku tshoveka ka brittle, ku creep ka mahiselo ya le henhla, matirhelo ya ku karhala, matimba ya ku tiyisela, ku lwisana na ku bola na ku lwisana na ku onhaka, na swin’wana . Xikombiso, S30403, S31603 Stainless Steel leyi tirhisiwaka ngopfu yinga tirhisiwa eka tindzhawu tale lwandle nale ka tindzhawu tin’wana, naswona yina ku tiya swinene ka corrosion. 16mndr, 09mnnidr low temperature steel nayona yina swivumbeko swa kahle swa low temperature toughness.
Swilo leswi kucetelaka swa matirhelo ya ku welda ka switirhisiwa swa nsimbi .
Swilo leswi vonakaka .
Switirhisiwa swikatsa switirhisiwa swale hansi na switirhisiwa swo welda. Ehansi ka swiyimo leswi fanaka swa ku welda, nchumu lowukulu lowu lawulaka ku welda ka nsimbi ya le hansi i swivumbeko swa yona swa xiviri ni xivumbeko xa tikhemikhali.
Swivumbeko swa physical swikatsa melting point, thermal conductivity, linear expansion coefficient, density, heat capacity na swin’wana swa nsimbi, hinkwaswo swina nkucetelo eka thermal cycling, melting, crystallization, phase change na maendlelo yan’wana, hindlela yaleyo swi khumba weldability. Switirhisiwa leswingana thermal conductivity yale hansi kufana na stainless steel swina gradient leyikulu ya mahiselo hinkarhi wa welding, high residual stress na deformation leyikulu. Ku tlula kwalaho, hikokwalaho ka nkarhi woleha wotshama eka mahiselo yale henhla, ti grains ta ndzhawu leyi khumbekaka hi kuhisa ya mila, leswi onhaka matirhelo ya nhlangano. Austenitic stainless steel yina linear expansion coefficient leyikulu, naswona deformation na stress swa joint swikulu swinene.
Hi mayelana na xivumbeko xa ti khemikhali, khaboni i elemente leyingana nkucetelo lowukulu eka swivumbeko swa ti khemikhali, leswivulaka leswaku nhlayo ya carbon ya swilo leswi yi boha weldability ya yona. Vunyingi bya swiaki swin’wana leswi hlanganisiweke eka nsimbi na swona a swi pfuni nchumu eka ku welda, kambe mpimo wa nkucetelo wa swona hi ntolovelo i wutsongo swinene ku tlula wa khaboni. Loko khaboni leyi nga eka nsimbi yi ya yi kula, mboyamelo wo nonon’hwa wa kula, kasi pulasitiki ya hunguteka, naswona ku welda ku pandzeka ku tala ku humelela. Hiku angarhela, ku twisisa ka switirhisiwa swa nsimbi eka ku pandzeka hi nkarhi wa ku welda na ku cinca ka swivumbeko swa michini swa ndzhawu ya nhlangano lowu weldiweke switirhisiwa tani hi swikombiso leswikulu swo kambela ku welda ka switirhisiwa. Hikokwalaho, loko nhlayo ya khaboni yiri e henhla, weldability yiva yi bihile swinene. Nsimbi ya khaboni ya le hansi na nsimbi ya alloy ya le hansi leyi nga na khaboni ya le hansi ka 0.25% yi na vuplasitiki bya kahle swinene na ku tiya ka nkucetelo, naswona ku tiya ka pulasitiki na ku khumbeka ka nkucetelo wa swihlanganisi swa welded endzhaku ka ku welda na swona swi kahle swinene. Akuna xilaveko xa preheating na post-welding heat treatment hinkarhi wa welding, naswona endlelo ro welda ra olova ku ri lawula, hikokwalaho rina weldability ya kahle.
Ku engetela kwalaho, xiyimo xa ku n’okisiwa na ku rhendzeleka, xiyimo xa ku hisa, na xiyimo xa xivumbeko xa nsimbi hinkwaswo swi nga khumba weldability hi tidigri to hambana. Ku antswisa weldability ya steel hiku antswisa, ku basisa kumbe ku antswisiwa ka mavele na thekinoloji yo rhendzeleka leyi lawuriwaka. Endzhaku ka loko nsimbi ya strip yi welded eka phayiphi, yi nga tlhela yi endliwa hi ku kongoma eka vutshunguri bya online bright solution. Hangao Tech (Michini ya Seko) . Induction Heating Muchini wo tshungula ku hisa ka furnace yo vangama wu nga antswisa ntshikelelo wa intergranular, leswi hungutaka ku tiya.
Switirhisiwa swo welda swi nghenelela hi ku kongoma eka nxaxamelo wa ti khemikhali ta metallurgical reactions eka endlelo ro welda, leswi lawulaka xivumbeko, xivumbeko, matirhelo na ku tumbuluxiwa ka swihoxo swa nsimbi ya weld. Loko switirhisiwa swo welda swi hlawuriwa hi ndlela yo ka yi nga ri kahle naswona swi nga fambelani na switirhisiwa swa le hansi, a hi ntsena swihlanganisi leswi fikelelaka swilaveko swa matirhiselo a swi nge kumiwi, kambe na ku tumbuluxiwa ka swihoxo swo fana na ku pandzeka na ku cinca eka xivumbeko na matirhelo ya xitirhisiwa swi ta nghenisiwa. Hikokwalaho, ku hlawuriwa lokunene ka switirhisiwa swo welda i nchumu wa nkoka ku tiyisisa swihlanganisi swa xiyimo xale henhla leswi weldiweke.
