A706 Weldable Rebar
ASTM A706 rebar yog ib qho kev qhia tshwj xeeb muab rau low-alloy txhawb cov tuav nyob rau hauv ob qho tib si standard lengths los yog coiled configurations. Qhov no qib rebar yog ua tiav nyob rau hauv qhib hearths, hluav taws xob furnaces, los yog yooj yim oxygen furnaces thiab muaj nyob rau hauv ntau heev qib , suav nrog qib 60i ib qib 80
Hais txog qhov no, puas yog tag nrho cov rebar weldable?
Feem ntau, tsuas yog steel rebar uas yog "Qib W" tuaj yeem welded. Rebar uas tsis yog tsim los rau ASTM A706 specification feem ntau tsis haum rau vuam tsis suav cov "carbon-sib npaug". Khoom siv nrog a carbon-equivalent tsawg dua 0.55 welded (AWS D1. 4).
Tom qab, lo lus nug yog, Qib 40 rebar puas tuaj yeem welded? Ob leeg qib raug suav hais tias yog ntau yam, tsis tshua muaj carbon, tsis muaj zog steels. Rebar feem ntau yog ua los ntawm cov txheej txheem 'kub dov' forging. Koj yuav tsum tau yooj yim vuam ob qho tib si qib 40 los yog qib 60 rebar ua ke; tab sis cov hlau hauv lub vuam cheeb tsam yuav ua ib tug casting ntawm khov hlau verses ib forging.
Kuj paub yog, Qib 60 rebar puas tuaj yeem welded?
AWS D1. 4, muaj peb txoj kev xaiv rau vuam rebar . Piv txwv li, yog A706 qib 60 bar yog welded ua a615 qib 60 bar, cov electrodes xav tau rau A615 qib 60 siv. Qhov no yog vim lub zog tensile ntawm A615 rebar yog 90,000 psi thaum A706 rebar tsuas yog 80,000 psi.
Kuv yuav ua li cas thiaj paub yog tias kuv tus welder yog rebar?
Qhov thib peb txoj kev qhia yog los ntawm kev nrhiav cov xim ntawm qhov kawg ntawm lub rebar . Yog hais tias nws yog tib xim ntawm ob kawg, lub rebar tsis yog weldable . Tab sis yog tias ib kawg yog xim liab thiab lwm qhov kawg yog xim txawv, nws tuaj yeem welded. Hauv qhov system no, dawb yog qib 33, daj yog qib 40 thiab ntsuab yog qib 60.

Qhov loj ntawm rebar yog dab tsi?
Common Rebar Sizes Rebar nyob rau hauv patios, hauv qab daus plag tsev, footings thiab driveways tej zaum yuav txawv ntawm qhov loj 3 mus rau 6. Cov neeg ua haujlwm qee zaum siv "1/8 Txoj Cai," txhais tau hais tias qhov loj ntawm lub rebar yog 1/8 lub thickness ntawm cov slab. Piv txwv li, ib lub slab uas yog 6 nti tuab yuav muaj rebar cim raws li loj 6 los yog 3/4-nti
