A: Vuam rods kuj muaj qhov du heev. Qhov saum npoo du no pab tsim kom muaj kev sib raug zoo ntawm ob daim hlau raug welded. Lub ntsej muag du kuj tseem pab tiv thaiv kev tsim ntawm qhov pores thiab lwm yam tsis zoo hauv cov vuam. Vuam rods tuaj nyob rau hauv ntau qhov ntau thiab tsawg.

Q: Yuav ua li cas fabrication ntawm structural steel ua hauj lwm?

A: Structural steel fabrication yog cov txheej txheem ntawm kev khoov, txiav thiab ua qauv hlau los tsim cov qauv. Rau cov qauv steel fabrication, steel qhov feem ntau muab tso ua ke los tsim cov qauv sib txawv ntawm qhov ntau thiab tsawg thiab cov duab.

Q: Hom welding yog cov qauv vuam zoo li cas?

A: Cov txheej txheem vuam yog txheej txheem ntawm kev tsim welds nrog cov khoom sib txawv los tsim, tsim, thiab txhim kho cov qauv welded. Cov txheej txheem vuam feem ntau yog siv los tsim cov qauv hlau rau cov tsev, txuas hniav, tsheb, thiab lwm yam kev tsim kho vaj tse.

Q: Dab tsi yog qhov zoo tshaj plaws tag nrho cov hom phiaj vuam pas nrig?

A: Rau feem ntau siv E6013 yog qhov zoo nyob ib puag ncig kev xaiv electrode. Nws tuaj yeem siv los txuas cov ntawv hlau, cov phaj hnyav, thiab tsuas yog hais txog txhua yam nyob nruab nrab.

Q: Yuav ua li cas koj xam welding rods?

A: Txhawm rau xam tus naj npawb ntawm cov welding rods koj xav tau, pib los ntawm kev txiav txim siab cov khoom siv qhov hnyav feem pua thiab qhov kub ntawm qhov vuam. Qhov kev xav tau ntawm vuam pas nrig yog txiav txim siab los ntawm kev sib npaug ntawm qhov hnyav feem pua ntawm cov khoom siv vuam nrog qhov nruab nrab ntawm cov cua sov tawm los ntawm lub vuam arc.

Q: Koj yuav faib cov welding rods li cas?

A: Yog li, ntawm no nws yog qhov kev faib cov hlau vuam mus li cas: thaum lub npe ua ntej yog R nws qhia vuam pas nrig, thaum nws yog E nws txhais tau tias vuam electrode; Thaum lub npe ua ntej yog RB, qhov no yog ib qho vuam pas nrig lossis cov hlua khi hlau, thiab thaum lub npe ua ntej yog ER, qhov no yog electrode pas nrig lossis vuam pas nrig.

Q: 4 tus lej txhais li cas ntawm lub vuam pas nrig?

A: Tus naj npawb "1" txhais tau tias nws yog txhua txoj haujlwm electrode; "2" qhia tias koj yuav tsum siv cov electrode rau txoj haujlwm tiaj tus thiab kab rov tav; thiab "4" txhais tau tias nws yuav ua haujlwm zoo tshaj plaws rau kev tiaj tus, kab rov tav, ntsug nqes, thiab nyiaj siv ua haujlwm.

Q: Qhov txawv ntawm 6011 thiab 6013 vuam pas nrig yog dab tsi?

A: E6011 thiab E6013 yog ob qho tib si vuam electrodes, tab sis lawv muaj qee qhov sib txawv tseem ceeb. E6011 yog lub zog hluav taws xob qis thiab siv rau cov txheej txheem vuam me me. Nws kuj tsis tshua ua rau hluav taws kub. E6013 yog lub zog hluav taws xob ntau dua siv rau cov txheej txheem vuam ntau dua.

Q: Dab tsi pas nrig muaj zog tshaj weld?

A: TIG vuam feem ntau suav hais tias yog qhov muaj zog tshaj plaws vim nws ua rau huab cua sov, thiab qhov txias txias ua rau muaj zog tensile thiab ductility. MIG kuj yog ib tus neeg sib tw zoo tshaj plaws rau hom kev sib txuas uas muaj zog tshaj plaws vim nws tuaj yeem tsim kev sib koom ua ke.
