Kho txoj kev rau excavator boom

Kev npaj ua ntej welding: Siv tes sib tsoo lub log kom tshem tawm cov roj stains, xim, xeb, thiab lwm yam los ntawm qhov qub weld seam tawg. Siv lub dav hlau dav hlau txiav tawm cov kab nrib pleb hauv qhov vuam seam, txiav nws mus rau lub cev ntawm lub vaj huam sib luag sab, thiab ntxuav qhov chaw tawv tawv ntawm cov khoom siv yav dhau los welded. Tom qab kev npaj, siv lub kaum sab xis sib tsoo lub log kom du qhov kev txiav (V-puab zawj yog tsim ntawm sab hauv interface). Tom qab ntxuav thiab tshuaj xyuas liab, paub meej tias tag nrho cov kab nrib pleb tau pom thiab tshem tawm.
Raws li kev saib xyuas uas twb muaj lawm, xaiv Φ 5mm qauv E5015 (J507) lossis E5016 (J506) vuam pas nrig yog ci ntawm 350 degree rau 2 teev, thiab tom qab ntawd insulated ntawm 100 degree kom tsis txhob ya raws qhov nqus ntawm vuam pas nrig. Nws tuaj yeem noj raws li xav tau; Vuam tam sim no yog 190-230A. Vim lub thickness loj ntawm excavator sab phaj, welded cheeb tsam yuav tsum tau preheated rau 150-250 degree ua ntej vuam; Thaum lub sij hawm vuam txheej txheem, segmented, symmetrical, thiab rov qab vuam txoj kev yuav siv tau; Thaum lub sij hawm txias txheej txheem ntawm weld seam, weld hlau yuav tsum tsis tu ncua ntaus nrog rauj kom tshem tawm kev ntxhov siab; Thaum vuam ntawm lub ces kaum ntawm lub vaj huam sib luag sab, txhawm rau kom tsis txhob muaj qhov tsis xws luag, kev txuas txuas txuas ntxiv tau pom zoo los txhim kho qhov kev ntxhov siab ntawm kev sib txuas.
Tom qab vuam, kom huv si tshem tawm spatter, vuam slag, thiab weld nodules, thiab weld seam qhov siab yuav tsum tsis pub tshaj 2.5 hli. Ua cov tshuaj sib nqus particle ntawm lub vuam seam, thiab tsis pub muaj kab nrib pleb lossis lwm yam tsis xws luag.
