### 1. Vim li cas Welded cov yeeb nkab tsis haum rau siab-} qhov kev siv siab?
Welded yeeb nkab feem ntau tsis haum rau siab -}} qhov kev thov feem ntau vim tias nws sab qab. Welded seam yog ib txoj kab muaj peev xwm ntawm kev qaug zog. Thaum lub sij hawm vuam, cov cua sov - kev sib tw ntawm niam txiv, ua rau muaj kev phom sij me me, thiab tsis muaj kev ntxhov siab rau kev ntxhov siab. Tsis tas li ntawd, muaj kev pheej hmoo ntawm cov suav nrog, porosity, lossis tsis muaj kev sib luag nyob rau hauv Weld nws tus kheej, uas tuaj yeem ua raws li cov ntsiab lus rau cov kab nrib pleb. Thaum lub sij hawm vuam niaj hnub thiab tsis- kev pheej hmoo sim ua tau zoo dua, qhov kev xaiv uas nyiam tshaj plaws thiab kev xaiv kev nyab xeeb thiab kev nyab xeeb} kev pabcuam siab.
### 2. Puas yog cov txiv ntseej kav ntev dua li welded?
Tsis tas yuav "muaj zog dua" nyob rau hauv cov nqe lus ntawm cov pib lub zog yooj yim, raws li ob qho tib si tuaj yeem ua rau tib cov ntaub ntawv qib qhab nia. Qhov tseem ceeb kom zoo dua ntawm seamless yeeb yog nws homogeneity thiab tsis muaj kev sib tw. Qhov no ua rau nws txhim khu kev qha thiab xwm yeem nyob rau hauv kev kub siab, hnyav heev, thiab corrosive tej yam kev mob. Tus qauv seamless muaj cov qauv sib dhos nyob ib ncig ntawm tag nrho ib ncig, ua rau nws tsis txaus ntseeg ntawm qhov tsis muaj zog. Yog li ntawd, thaum lub siab - Zoo Welded cov yeeb nkab tej zaum yuav suav hais tias yog ib qho kev sib tw yog qhov muaj zog ntau dua thiab muaj peev xwm rau cov ntawv thov xav tau.
### 3. Dab tsi erw sawv hauv cov yeeb nkab?
ERW sawv rau ** Hluav Taws Xob Hluav Taws Xob Vuam **. Nws yog tus txheej txheem uas cov yeeb nkab tsim los ntawm cov hlau uas siv hlau thiab cov leeg yog welded los ntawm kev thov nias thiab hluav taws xob. Cov khoom siv tam sim no los ntawm kev tiv thaiv hluav taws xob, uas fuses cov npoo ntawm cov hlau sawb ua ke yam tsis muaj kev siv cov tub lim hlau. Niaj hnub new cov txheej txheem, tshwj xeeb high -}}}}}}} {{{5} {{5} - zoo welds.
### 4. Dab tsi yog qhov teeb meem nrog cov yeeb nkab vuam?
Qhov teeb meem tseem ceeb nrog cov yeeb nkab vuam yog ua kom muaj kev sib xws, tsis ua haujlwm weld thoob plaws, thiab tag nrho cov yeeb nkab qhov chaw, tshwj xeeb tshaj yog thaum cov yeeb nkab tau tsau rau hauv txoj haujlwm. Cov kev sib tw tseem ceeb xws li:
* ** Kev nkag mus tau thiab txoj haujlwm: ** Welders feem ntau yuav tsum ua haujlwm nyob rau hauv txawv txawv txoj haujlwm (piv txwv, ntsug, ntsug) mus rau weld ib qho yeeb nkab tsau, uas tuaj yeem ua rau tsis taus.
* ** Kev tswj cua sov: ** Tswj cov lus sov sov yog qhov tseem ceeb. Ntau dhau cua sov tuaj yeem ua rau tsis muaj qhov fusion, thaum ntau heev cua sov tuaj yeem hlawv los ntawm cov yeeb nkab phab ntsa los yog tsim ib qho tsis muaj zog, brittle}} kub thaj chaw.
* ** Kev sib txawv: ** Qhov kub heev los ntawm vuam ua rau cov yeeb nkab ua rau cov yeeb nkab ua kom nthuav dav thiab cog lus, muaj peev xwm ua rau misalignment thiab distortion ntawm lub rooj sib txoos kawg.
* ** Kev tsis xws luag: ** Cov Yeeb Nkab Welds muaj peev xwm nquag yog qhov tsis xws luag, tawg, thiab tsis tiav kev ncaj ncees ntawm tag nrho cov kab ke.
### 5. Dab tsi yog ib qho yuam kev hauv cov yeeb nkab vuam?
Ib qho kev ua yuam kev thiab tseem ceeb heev hauv cov yeeb nkab vuam yog ** cov txheej txheem tsis raug cai thiab tsis nkag rau **. Lub hauv paus pib yog thawj Weld Bead tso rau hauv kev sib koom ua ke, thiab nws yog lub hauv paus rau txhua txheej Weld tom ntej. Yog tias lub hauv paus dhau tsis tua kom raug- qhov kev sib koom tes huv si (qhov chaw weld tsis txaus ntseeg Cyclic chaw thau khoom. Lwm cov kev ua yuam kev uas suav nrog kev npaj ua ke tsis zoo, lub kaum ntse hluav taws xob lub kaum, thiab nrawm mus txawv tebchaws ceev.
