Kev tsis xws luag thiab kev tiv thaiv ntawm welded yeeb nkab

Cov teeb meem uas tsim los ntawm cov khoom siv hluav taws xob ntau zaus welded kav (astm a53 qib b erw yeeb nkab) qee zaum tsis tshwm sim los ntawm ib qho laj thawj, tab sis feem ntau yog tshwm sim los ntawm kev sib xyaw ntawm ntau yam.Vuam tsis xws luag kuj tuaj yeem tshwm sim los ntawm lwm cov laj thawj sab nraud ntawm qhov chaw vuam, yog li ntau yam yuav tsum tau txiav txim siab dav dav rau qhov tsis xws luag, qhov teeb meem tuaj yeem daws tau los ntawm kev ua tib zoo tshuaj xyuas cov laj thawj.

suav nrog

Kev tsim cov txheej txheem ntawm kev suav nrog cov tsis xws luag yog tias cov hlau oxide tsis yog extruded nrog cov hlau molten, tab sis yog sandwiched rau ntawm qhov chaw vuam.

Cov hlau oxides no feem ntau yog tsim nyob rau saum npoo ntawm cov hlau molten ntawm V lub kaum sab xis.Thaum lub sawb ntug mus txog qhov ceev yog qis dua qhov ceev ntawm melting ceev, thiab lub melting ceev yog siab tshaj qhov tso tawm ceev ntawm cov hlau molten, lub apex ntawm lub V-shaped qhib yuav tsim ib tug molten hlau thiab kev koom tes ntawm cov hlau oxides tsis tau kiag li. tso tawm tom qab ib txwm extrusion.Qhov saum npoo ntawm cov hlau huv huv yog doped nrog cov hlau oxides, yog li tsim qhov tsis xws luag hauv cov txheej txheem forging thiab vuam.

Qhov kev tsis zoo no yuav ua rau lub vuam tawg tom qab raug flattened, thiab cov kev sib txuas yuav pom ntawm qhov tawg ntawm qhov vuam.Qhov kev tsis zoo no muaj nyob rau hauv ntau hom, qee zaum ib leeg, qee zaum hauv cov saw hlau.

Kev tiv thaiv kev ntsuas rau kev suav nrog qhov tsis xws luag:

1. Lub kaum sab xis V yog nruj me ntsis tswj tsis pub dhau 4 ~ 6
2. Chav tsev hloov kho kom ruaj khov qhib lub kaum sab xis ntev
3. Qhov sib piv Mn/Si hauv cov tshuaj muaj pes tsawg leeg ntawm cov sawb yog ntau dua 8: 1
4. Txo cov oxidation ntawm qhov chaw vuam

Pre-arc

Qhov kev tsis zoo no yog qhov tsis txaus fusion tshwm sim los ntawm pre-arc.Feem ntau, qhov burr lossis oxide nplai thiab xeb ntawm ntug ntawm lub sawb tsim ib tug choj ua ntej lub apex ntawm V lub kaum sab xis, uas ua rau lub luv luv Circuit Court ua rau cov tam sim no dhia thiab tsim cov pre-arc phenomenon, thiab luv luv Circuit Court. tam sim no hloov cov kev taw qhia tam sim no thiab txo Cov cua sov ntawm V ces kaum yog txo.

Cov teeb meem tshwm sim los ntawm instantaneous shunting, lub ci ntsa iab dav hlau tawg tuaj yeem pom los ntawm cov pob txha tawg, qee zaum tsis muaj kab txaij ntug burr lossis oxide nplai, xeb, thiab lwm yam, tab sis me me V lub kaum sab xis lossis siab dhau yuav ua rau ua ntej. arc phenomenon, Qhov no yog tshwm sim los ntawm high voltage tawm ntawm ntug ntawm lub sawb.

Kev tiv thaiv kev tiv thaiv rau pre-arc defects:

1. Lub kaum sab xis V yog nruj me ntsis tswj tsis pub dhau 4 ~ 6
2. Lub ntug ntawm lub sawb yog huv si, du thiab tsis muaj burrs
3. Ua kom cov dej txias kom huv si, tswj cov kev taw qhia ntws ntawm cov dej txias, thiab sim zam qhov kev taw qhia V lub kaum sab xis.

fusion tsis txaus

Qhov teeb meem no yog vim lub fact tias cov npoo ntawm ob lub strips yog rhuab tab sis tsis tag fused, thiab ib tug zoo weld tsis tsim.Qhov ncaj qha ua rau tsis txaus fusion yog tsis txaus thaum lub sij hawm vuam.Muaj ntau yam cuam tshuam uas ua rau lub vuam tsis txaus, xws li lub zog muaj zog.Cov zis, V lub kaum sab xis thiab cua sov ntev, txoj hauj lwm ntawm cov hlau nplaum bar, kev ua hauj lwm thiab txias ntawm cov hlau nplaum bar, qhov loj ntawm induction coil, vuam ceev, thiab lwm yam. ua rau muaj qhov tsis xws luag.

Kev tiv thaiv kev tiv thaiv tsis txaus fusion defects:

1. Qhov sib txuam ntawm vuam input cua sov thiab vuam ceev, cov yam ntxwv ntawm cov khoom siv raw ntawm lub raj tsis muaj
2. Kev ua haujlwm ntawm magnetic bar
3. V lub kaum sab xis thiab cua sov ntev
4. Induction coil specifications

Kev ruaj ntseg thiab zoo ntawm cov khoom siv yog cov hauv paus ntsiab lus kom tsis txhob muaj qhov tsis xws luag.Ua kom tiav cov ntaub ntawv thiab kev tshuaj xyuas ntawm cov txheej txheem tsis tuaj yeem ua kom cov kav dej zoo.
