Dab tsi yog lub hauv paus ntsiab lus ntawm "siab-frequency resistance welding" hauv ERW txheej txheem?
Siab - zaus kuj welding (ERW)yog ib qho ntawm feem ntau siv vuam txoj kev rau steel kav, tshwj xeeb tshaj yog haum rau zus tau tej cov me me thiab nruab nrab txoj kab uas hla steel kav. Nws lub hauv paus ntsiab lus yog kom sov lub ntug ntawm cov yeeb nkab steel mus rau nws melting point, thiab ces welded ob kawg ntawm steel yeeb nkab ua ke nyob rau hauv qhov kev txiav txim ntawm siab - zaus tam sim no thiab sab nraud siab.
Vim li cas feem ntau S235JR ERW welded kav yuav tsum tau kho cua sov?
Vim tias qhov kub siab thaum lub sij hawm vuam hloov cov qauv hlau nyob rau hauv qhov chaw vuam, ua rau nws tawv thiab ua nkig. Kev kho cua sov (sib npaug rau "annealing" weld) tshem tawm qhov brittleness, rov qab mus rau theem ntawm kev hloov pauv thiab cov khoom siv kho tshuab zoo ib yam li cov khoom siv hauv paus, yog li ua kom lub zog zoo ib yam thoob plaws hauv cov yeeb nkab thiab ua kom muaj kev nyab xeeb rau kev siv.
Yuav ua li cas tsis yog -kev kuaj kev puas tsuaj feem ntau yog siv los xyuas kom meej weld zoo thiab kev ntseeg tau?
Tsis yog -kev kuaj kev puas tsuaj (NDT) yog cov txheej txheem kev soj ntsuam uas siv los tshuaj xyuas cov khoom, cov khoom, lossis cov qauv yam tsis muaj kev puas tsuaj. Qhov txiaj ntsig tseem ceeb ntawm NDT yog tias nws tswj kev ncaj ncees ntawm cov khoom raug sim thiab txo qis kev cuam tshuam ntau lawm. Cov kev siv feem ntau yog kuaj ultrasonic thiab eddy tam sim no kuaj. Qhov no yog sib npaug rau kev kuaj xyuas ultrasonic thiab electrocardiogram (ECG) ntawm qhov vuam.
Dab tsi yog qhov zoo ntawm S235JR siab -frequency resistance welded yeeb nkab?
S235JR Siab - zaus kuj welded yeeb nkabcombines high efficiency, tsis tshua muaj nqi, thiab high precision, ua rau nws yog ib qho ntawm feem kev sib tw khoom nyob rau hauv niaj hnub yeeb nkab manufacturing. Hauv qhov tsis yog - siab - siab lossis tsis - ib puag ncig hnyav, nws maj mam hloov cov kav dej tsis sib haum thiab dhau los ua qhov kev xaiv tseem ceeb hauv kev ua lag luam.
Dab tsi yog daim ntawv thov thaj chaw ntawm S235JR siab -frequency resistance welded yeeb nkab?
Nws yog dav siv nyob rau hauv ntau yam qauv thiab cov dej thauj mus los qhov chaw uas yuav tsum tau siab tsis heev. Cov kev siv feem ntau suav nrog: cov khoom siv xws li railings thiab kev txhawb nqa hauv cov tsev, cov kav dej, cov kav dej cua sov, thiab cov cua ducts hauv nroog engineering, thiab nws kuj yog siv los ua cov yeeb nkab xa mus rau cov roj thiab cov kab hauv cov khoom siv tshuab.
