Cov lus nug ntawm seb tus pas nrig (thaiv npog hlau vuam Cov lus teb yog nyob ntawm ntau yam ntawm cov yam ntxwv, suav nrog hom khoom, tsim qauv tsim, thiab tus neeg teb xov xwm kev txawj. Tsis yog txoj kev tau muaj zog thoob plaws thoob plaws txhua qhov xwm txheej, tab sis txhua yam muaj zog uas ua rau nws txhim khu kev qha hauv cov ntawv thov tshwj xeeb.
Cov ntsiab lus tseem ceeb txiav txim siab Weld lub zog
Weld lub zog yog feem ntau txiav txim siab los ntawm peb tus tseem ceeb: Fusion, nkag mus, thiab cov khoom siv mechanical ntawm weld hlau. Fusion hais txog txoj kev sib xyaw ua ke hlau thiab muab tub lim cov khoom sib xyaw ntawm cov pob qij txha ua rau cov ntsiab lus tsis muaj zog uas weld tuaj yeem sib cais. Kev nkag mus, qhov tob tob uas tus weld nkag mus rau cov hlau hauv paus, kom cov sib koom tes tuaj yeem tiv taus kev ntxhov siab ntawm lub interface. Cov khoom siv ua kom haum rau tensile lub zog, ductility, thiab kev tiv thaiv kom tawg kuj ua lub luag haujlwm tseem ceeb; Piv txwv li, ob lub pas thiab Mig siv cov tub rog sib tw ua haujlwm los ntawm tensile lub zog (piv txwv li, 70,000 qhov kev ntaus nqi no rau lub hauv paus hlau yog qhov tseem ceeb.
Tus neeg teb xov tooj kev txawj yog ib qho tseem ceeb. A poorly executed MIG weld with insufficient penetration will be weaker than a well-done stick weld on the same material, and vice versa. Kev nyiam huv, ua ntej {- weld npaj (xws li kev tswj hwm kub, thiab brittleness zoo, los yog undermining Weld lub siab dawb paug.
Pas vuam welding: lub zog hauv cov xwm txheej tawv
Lo vuam zoo nkauj hauv kev tsim cov khoom siv muaj zog hauv cov chaw sib tw, uas ua rau nws lub koob npe nrov rau kev ua haujlwm ntev. Nws lub peev xwm los ua haujlwm nrog cov ntaub ntawv qias neeg, xeb, ua tsaug rau cov txheej txheem weld uas nws tuaj yeem ua tiav kev npaj fusion zoo txawm tias kev npaj khoom saum npoo tsawg. Qhov no yog qhov tseem ceeb ntawm kev kho lossis cov chaw tsim kho uas yuav ua kom huv si tsis tau txais kev sib kis hauv Mig Vuam tuaj yeem tuav tau muaj zog.
Lo electrodes zoo li 7018 yog tsim rau lub zog siab thiab hydrogen cov ntsiab lus, ua rau lawv zoo tagnrho rau cov txheej txheem steel vuam. Lub hydrogen blux minimizes kev pheej hmoo ntawm hydrogen - Qhov ua tsis tau muaj kev tawg, qhov siab {{3} {muaj zog hlau. Pas vuam kuj muaj kev nkag tob tob, tshwj xeeb yog cov hluav taws xob loj dua, uas yog qhov tseem ceeb rau koom nrog tuab cov ntaub ntawv (1/2 nti lossis ntau dua). Hauv cov ntawv thov uas zoo siab rau ntawm kev siv hluav taws xob lossis kev tsim kho choj, qhov twg ESS yuav tsum muaj kev ntxhov siab ntau rau cov qauv no thiab tus lej tsis zoo.
Mig vuam: sib xws tsav kev ntseeg tau
Mig vuam lub zog nyob rau hauv nws xwm yeem, uas txo qhov kev pheej hmoo ntawm tib neeg kev ua yuam kev uas tuaj yeem tsis muaj zog Welsed. Lub tshuab xaim hluav taws xob pub thiab ruaj khov arc (thaum teem arc (thaum teeb tsis sib xws) kev nkag mus rau hauv nruab nrab-} ate). Qhov xwm txheej sib xws yog qhov tseem ceeb hauv huab hwm coj ntau lawm, qhov twg ua tau weld zoo yog qhov tseem ceeb thiab cov tshuab sib txawv feem ntau muaj qhov tsis xws luag lossis tsis sib xws, ua rau muaj zog txo qis.
MIG siv cov ntaub thaiv npog (Argon, COG, lossis sib xyaw ua si Weld Weld, uas tau txais txiaj ntsig huv si thiab tsis muaj hlau. Tsis zoo li lo ntaub vuam, uas yog qhov ua tau zoo dua ntawm txhuas vim yog cov teeb meem oxide thiab cov xaim hluav taws xob ua kom muaj zog, caiv weet ntawm cov ntaub ntawv no. Piv txwv li, Mig - Welded Txhuas cov pob qij txha sib ntsib vim tias cov ntaub thaiv cov roj av tiv thaiv oxidation, ua kom muaj zog ua kom zoo, ua kom muaj zog.
MIG tseem muaj cov versatility hauv kev muab tub lim cov kev xaiv. High - Lub zog siv hluav taws xob (piv txwv li cov qauv muaj zog, thiab cov qauv siv hluav taws xob (zoo li cov neeg siv hluav taws xob uas muaj zog nyob rau hauv ib puag ncig uas durability yog nyob ntawm ntau dua tsuas yog tensile muaj zog.
Muab lub zog piv rau hauv tiag - ntiaj teb kev sib tw
On tuab carbon hlau (1 nti +), lo vuam vuam feem ntau muaj ib tug ntug vim nws lub peev xwm los lis ntau tus dhau yam tsis poob fusion. Cov tshuab hluav taws xob tsawg siv hauv cov vuam vuam kuj tseem txo cov kab sib tsoo hnyav hauv cov ntu hnyav, cov nqi cua txias yog qeeb thiab cov hydrogen tuaj yeem ua rau daig. Mig vuam tuaj yeem ua tiav lub zog zoo sib xws ntawm cov hlau tuab tab sis yuav tsum tau ceev faj teeb tsa (ntau dua cov khoom lag luam) thiab huv si kom tsis txhob muaj kev tsis xws luag.
Rau cov ntaub ntawv nyias nyias (16 ntsuas cua mus rau 1/4 nti), Mig vuam feem ntau ua cov khoom muaj zog dua. Nws precise tshav kub tswj tau txo txoj kev pheej hmoo ntawm hlawv cov kev pheej hmoo ntawm hlawv cov kev pheej hmoo ntawm kev kub ntxhov, uas tuaj yeem ua rau muaj cov hluav taws xob tsis muaj zog thaum siv cov hluav taws xob tsis muaj zog thaum siv cov hluav taws xob tsis muaj zog thaum siv hluav taws xob tsis muaj zog thaum siv cov hluav taws xob tsis muaj zog thaum siv cov hluav taws xob tsis muaj zog thaum siv cov hluav taws xob tsis muaj zog thaum siv cov hluav taws xob me me thaum siv cov hluav taws xob tsis muaj zog thaum siv cov hluav taws xob tsis muaj zog thaum siv cov hluav taws xob tsis muaj zog thaum siv cov hluav taws xob tsis muaj zog thaum siv cov hluav taws xob tsis muaj zog thaum siv cov hluav taws xob tsis muaj zog thaum siv cov hluav taws xob me me thaum siv cov hluav taws xob tsis muaj zog thaum siv cov hluav taws xob tsis muaj zog thaum siv cov hluav taws xob me me thaum siv cov hluav taws xob tsis muaj zog thaum siv cov hluav taws xob tsis muaj zog thaum siv cov hluav taws xob me me thaum siv cov hluav taws xob tsis muaj zog thaum siv cov hluav taws xob tsis muaj zog thaum siv cov hluav taws xob tsis muaj zog thaum siv cov hluav taws xob tsis muaj zog thaum siv cov hluav taws xob tsis muaj zog thaum siv cov hluav taws xob me me thaum siv cov hluav taws xob tsis muaj zog thaum siv cov ntaub ntawv me me. Cov hnav ris tsho zoo nkauj profile ntawm Mig ves kuj tau faib cov kev ntxhov siab ntau tusyees hla kev sib koom ua ke, tiv thaiv kev ntxhov siab cov ntsiab lus.
Nyob rau sab nraum zoov lossis cua hlob, lo vuam tswj hwm lub zog kom muaj zog dua vim nws cov txheej txheem huab cua tsis cuam tshuam los ntawm huab cua txav, tsis zoo li Mig cov roj ntaub thaiv. Mig weld excos tuaj yeem txhim kho porosity (me me roj npuas) uas tsis muaj zog ntawm kev sib koom ua ke, thaum ib tug stick weld tib yam mob tseem yog suab. Hloov siab, hauv kev tswj hwm sab hauv tsev, Mig cov kev ua kom huv, muaj kev sib phim ntau lossis ntau dua lo weld lub zog ntawm cov ntaub ntawv sib piv.

Tsis txhob lo lo nplaum los yog Mig vuam yog cov muaj zog thoob ntiaj teb- lawv cov kev ua tau zoo nyob ntawm daim ntawv thov. Pas vuam muaj zog rau tuab, qias neeg, lossis siab- lub zog steel nyob rau hauv kev xaiv hnyav thiab hydrogen xaiv. Mig vuam excenels nyob rau hauv cov ntaub ntawv huv, ntxuav cov ntaub ntawv ntawm nyias rau nruab nrab cov ntaub ntawv (suav nrog cov khoom siv uas tswj tau qhov twg txo cov kev tsis xws luag.
Thaum kawg, tus muaj zog tshaj plaws Weld tau txiav txim siab los ntawm kev xaiv txoj cai rau cov khoom siv, tsim qauv sib koom ua ke, ua ke nrog cov txheej txheem tsim nyog. Ib tus neeg ua haujlwm txawj ntse siv pas vuam ntawm tus txheej txheem steel nqaj yuav ua kom muaj zog weld ntau dua li cov neeg tsis muaj zog tshaj plaws ntawm tib cov ntaub ntawv, thiab hloov ua lwm yam. Ob txoj kev muaj peev xwm ntsib lub zog siab tshaj plaws- Qhov tseem ceeb tshaj plaws yog txuam nrog cov txheej txheem rau lub luag haujlwm.
