Kuv yuav xaiv txoj hlua yog li cas?

Xaiv txoj cai vuam coloy yog qhov tseem ceeb rau kev tsim cov khoom siv muaj zog, phim rau cov khoom lag luam hauv paus ntawm nws lub sijhawm. Cov txheej txheem cuam tshuam nrog lub hauv paus hlau lub zog, lub hom phiaj weld lub hom phiaj, thiab cov xwm txheej vuam txoj kev ua tiav yuav ntsib. Los ntawm kev tsom mus rau cov ntsiab lus tseem ceeb koj tuaj yeem xaiv ib qho alloy uas ua kom muaj kev ntsuas zoo, lub zog, thiab ntev.
Pib los ntawm kev sib txuam ntawm cov alloy rau lub hauv paus hlau. Txoj cai tseem ceeb tshaj plaws yog siv cov alloy uas ua tiav cov hlau koj vuam. Piv txwv li cov hlau me me ua haujlwm zoo tshaj plaws nrog carbon hlau alloys zoo li e70s - 6 uas ntais nws lub zog thiab weldability. Stainless hlau yuav tsum muaj cov khoom siv hlau stainless -}}}}}}}}}}}}}}}}}}}}}}}} tus hlau stainless thiab 316 stainless siv tshuaj corrosion. Aluminium xav tau aluminium- Raws alloys xws li ER4043 (rau 6061 Aluminium) lossis Er5356 (rau cov tubrog -}}} Tooj liab thiab nws cov alloys (tooj dag bronze) khub nrog tooj liab {}}}}} A) uas tiv thaiv kev oxidation thiab ua kom haum. Kev tsis sib xws alloys tuaj yeem ua rau cov pob qij txha tsis muaj zog lossis tshuaj lom neeg uas puas siv cov hlau allloy rau Aluminoy ntawm Alloy ntawm Stainless Hlau.
Tom ntej no xav txog WELD lub zog yuav tsum tau ua. Cov Alloy yuav tsum tau muab lub zog txaus kom tsis txhob ua kev ua ib qho chaw tsis muaj zog nyob rau hauv ib feem. Rau General - lub hom phiaj phiaj xwm zoo li cov hlau me me siv ib qho kev sib txuas ntawm cov hlau (60000-70000 PSI rau cov hlau me). Txog siab - Kev Siv Kev Siv Kev Nyuaj Siab xws li cov hlab ntsha siab lossis cov tshuab hnyav uas muaj lub zog me me ({} psi) thiab kev tiv thaiv mus tawg. Rau lub teeb yuag tab sis muaj zog ntu zoo li txhuas lub tsheb kauj vab Siv ER5356 Alloy Alloy uas ntxiv magnesium los txhawb lub zog tsis muaj zog ntxiv tsis muaj qhov hnyav ntxiv. Txhua zaus yuav tsum tshawb xyuas lub taub hau alloy lub qhov hluav taws xob lub zog (teev rau ntawm cov ntawv ntim lossis kom nws ua tau lossis ntau dua ntawm cov hlau lub zog.
Soj ntsuam qhov ib puag ncig Weld yuav ntsib. Cov alloys sib txawv tiv thaiv sib txawv yog li xaiv ib qho uas sawv rau cov xwm txheej ua tiav daim ntawv tiav yuav ntsib. Txog kev ua kom muaj chaw muaj teeb meem lossis cov nroj tsuag tshuaj siv cov hlau stainless hlau alloys (316L rau Salty) lossis Nickel {}} raws li alloys (monel rau acid tsis kam). Txog siab - sov daim ntawv thov xws li cov khoom siv hluav taws xob lossis cov cav ntoo uas tau txais lub zog ntawm 2000℃F lossis siab dua. Rau qhov chaw txias xws li Arctic Pipelines siv qis - d2) uas resistions brittleness nyob rau hauv khov qhov chaw sov. Txog cov ntawv siv hluav taws xob xws li tooj liab bus tooj liab -} raws li alloys (silicon bronze) uas tswj hwm kev ua haujlwm. Tsis quav ntsej ib puag ncig muaj peev xwm ua rau ua tsis siav-} txawm tias lub alloy tsis tuaj yeem lis nws ib puag ncig.
Phim cov alloy rau koj cov txheej txheem vuam. Tsis yog txhua txoj haujlwm ua haujlwm nrog txhua txoj kev vuam yog li xaiv ib qho tshaj tawm nrog koj cov cuab yeej siv. Mig vuam yuav tau txais cov alloys hlau (piv txwv li, e70s-}}} 6 rau txhuas) uas pub dawb huv los ntawm lub tshuab. Tig Vuam siv cov qaws- cov duab alloys (piv txwv li, 308l pas rau stainless hlau) uas yog pub rau hauv weld pas dej. Stick Vuam relies ntawm coated electrodes (piv txwv li, E60 E6013 rau cov hlau me) qhov twg flux txheej tiv thaiv lub weld. Flux - Cov Qauv Vuam Siv Flux-} E71T-8 rau cov roj av) uas yuav tsis xav tau cov pa roj. Siv cov txheej txheem alloy tsim rau cov txheej txheem sib txawv tuaj yeem ua rau sib xws, lossis cov cuab yeej ua tsis zoo, lossis cov khoom siv jams-ib txwm txheeb xyuas tias cov alloy yog sau rau koj txoj kev vuam.
Txheeb xyuas cov cai tshwj xeeb. Qee qhov haujlwm xav tau cov khoom ntxiv uas dhau ntawm qhov tseem ceeb lossis corrosion tsis kam. Rau cov hniav zoo li hlau daim duab xaiv tooj liab- based silicon bronze uas muaj lub ntsej muag ua tiav thiab txhuam tau zoo. Rau cov hnav -} Cov khoom tiv thaiv zoo li gears lossis li qub siv cobalt {{5} Taug kev (stellite) uas tiv thaiv kev sib txhuam thiab puas tsuaj. Rau cov hlau nyias lossis eg, aluminium nplooj ntawv) siv alloys nrog zoo ntws cov khoom (ER4043) kom tsis txhob hlawv - los ntawm. Rau cov zaub mov-} Cov khoom siv qib qis (piv txwv li, cov roj stainless hlau) siv qis dua cov alloys alloys (30L) kom tiv thaiv kom paug.
Thaum kawg xeem thiab kho raws li xav tau. Yog tias koj tab tom ua haujlwm ntawm txoj haujlwm tseem ceeb hauv kev sim Weld ua ntej. Txheeb xyuas cov cim ntawm kev tsis zoo fusion (khoob ntawm weld thiab luj hlau) porosity (me ntsis npuas (me me- cov new incomple alloy. Yog hais tias tus xeem weld yog tsis muaj zog sim ib siab dua- Lub zog allloy lossis ib qho nrog deoxidizing zoo dua (piv txwv li E70S-6 hloov E6013 rau cov hlau). Yog tias xeb yog kev txhawj xeeb kev txhawj xeeb weld hauv ib qho chaw sim (piv txwv li, qab ntsev rau cov av marine) thiab kos rau xeb lossis pitting tom qab ob peb hnub.
Xaiv txoj cai vuam Alloy los rau txuam nrog lub hauv paus hlau, ua ntej ntawm Weld cov kev xav tau (corrosion tsis kam, thiab lwm yam), thiab ua kom muaj kev sib xyaw nrog koj cov txheej txheem. Los ntawm kev tsom mus rau cov xwm txheej no koj yuav xaiv ib qho alloy uas tsim muaj zog, txhim khu kev qha velds tsim kom kawg.
