S355J2H Qauv ERW Steel Yeeb Nkab

S355J2H tsis kam welded yeeb nkab yog cov yeeb nkab uas tsis tshua muaj alloy siab-zog steel yeeb nkab. Nws yog tsim los ntawm cua sov thiab koom nrog hlau lossis lwm yam khoom siv thermoplastic xws li yas los ntawm kev tsim khoom thiab cov txheej txheem. Txoj kev no suav nrog kev siv lub siab nrog cov electrodes rau lub rooj sib dhos ua haujlwm thiab siv cov hluav taws xob tiv thaiv hluav taws xob uas tsim los ntawm kev sib cuag ntawm qhov sib koom tes thiab thaj chaw uas nyob ib sab los ua vuam. S355J2H cov qauv welded kav yog siv rau hauv kev tsim kho, txuas hniav, nkoj, tsheb, lub nkoj siab, thiab lwm yam qauv.

Dab tsi yog Vuam Txoj Cai ntawm Resistance Welded Pipe?

Resistance welding yog ib txoj kev vuam uas siv cov cua sov ua kom lub zog. Nws suav nrog electroslag vuam, uas siv slag kuj tshav kub, thiab tsis kam vuam, uas siv cov khoom ua haujlwm kub. Thaum cov hluav taws xob tam sim no dhau los ntawm tus neeg xyuas pib, cov cua sov yog tsim los ntawm kev ua haujlwm. Nrog rau qhov tam sim no tsis tu ncua, qhov ntau dua qhov tsis kam, qhov kub ntau yog generated. Thaum ob daim hlau nyob rau hauv kev sib cuag, qhov kev tiv thaiv kev tiv thaiv yog ntau dua li qhov kev tiv thaiv sab hauv ntawm cov hlau. Yog li ntawd, thaum lub sij hawm tam sim no loj dhau los ntawm qhov chaw sib cuag, cov hlau nyob ze heats sai sai rau lub xeev kub kub thiab tau txais cov yas siab. Lub sijhawm no, kev siv lub siab yuav txuas ob daim hlau rau hauv ib chav tsev.

Hauv kev ua haujlwm vuam, cov khoom ua haujlwm tau muab tso rau hauv ib qho ntawm cov electrode siab, thiab cov cua sov uas tsim los ntawm cov hluav taws xob tam sim no dhau los ntawm cov khoom ua haujlwm melts qhov chaw sib cuag ntawm ob lub workpieces, yog li ua tiav cov vuam. Feem ntau, siv cov tam sim no loj. Txhawm rau tiv thaiv arcing ntawm qhov chaw sib cuag thiab txhawm rau txhawm rau vuam hlau, lub siab yuav tsum tau thov tsis tu ncua thaum lub vuam txheej txheem. Rau hom kev tiv thaiv vuam no, qhov saum npoo ntawm cov khoom ua haujlwm yog qhov tseem ceeb tshaj plaws rau kev ua tiav qhov ruaj khov weld zoo. Yog li ntawd, qhov chaw sib cuag ntawm cov electrodes thiab workpieces, nrog rau ntawm cov workpieces lawv tus kheej, yuav tsum tau ntxuav ua ntej vuam.
