Ib suam ntawm welds thiab pob qij txha

Cov hauj lwm zoo thiab kev ua tau zoo yog nyob ntawm seb cov nyob rau ntawm lub cuab tam cov ntaub ntawv thiab kev txawj ntse. Yuav kom kawm tau ntawv zoo nyob rau hauv tej lag luam, tsis muaj teeb meem dab tsi coj nws yog, ho influences kuj paub txog qhov kev tshawb xav. Vuam ua hauj lwm yog xav tau ntawm cov feem ntau.

Rau no hom ntawm kev ua si yog tsim nyog cov ntaub ntawv uas, cov khoom, kev kawm txawj thiab theoretical kev txawj ntse. Muaj mastered rau ntaub ntawv tsim nyog, tus neeg tau txais ib lub tswv yim dab tsi ib leeg uas muaj ib tug kev faib ntawm welds thiab yuav ua li cas los xaiv qhov zoo tshaj plaws kev xaiv rau cov coupling ntawm ntau yam hlau cov khoom.

Yuav ua li cas yog ib tug weld?

Thaum lub sij hawm vuam txheej txheem peb hlau feem: interconnected los ntawm peb, uas ua raws li ib tug electrode sib raug zoo rau ob daim hlau. Thaum lub hlws ris ntawm txhua lwm yam nws yog xim hlau qhov chaw tshwm sim thermal txheej txheem, txoj kev ua ib leeg. Yog li, lub leeg - nws yog ib feem ntawm cov hlau qauv, uas ua los ntawm raug fused thiab solidified hlau.

Pub ntxiv tshaj los ntawm vuam yuav ua tau tej co. Lawv muaj lawv cov kev qauv, raws li uas tus xaiv kev hom fastening. Ib suam ntawm welds ua, nyob ntawm seb lub coupling hom, cov khoom, thiab lwm yam tsis. Rau txhua compound nws muaj nws tus kheej cov kev cai thiab lawv txiav txim ntawm tua.

qhov ntev

Muaj yog ib tug faib ntawm welds nyob rau hauv ntev. Nyob ntawm seb tus loj, lub welds yog:

• Luv. Qhov luaj li cas tsis pub tshaj 30 cm. Tej leeg tshwm raws li ib tug tshwm sim ntawm welding, ua nyob rau hauv ib tug kev taw qhia los ntawm thaum pib mus rau thaum xaus.
• Nruab nrab. leeg ntev - 30 cm mus rau 1 'meter'. Cov nqaws yog welded los ntawm sab hauv mus rau sab nraum. Rau lawv, qhov zoo tagnrho txoj kev uas yuav rov qab-kauj ruam. Nws essence lies nyob rau hauv lub fact tias tag nrho leeg yog muab faib ua ob peb seem, uas nyob rau hauv lem yog ua los ntawm Vuam. Txhua yam ntawm cov feem muaj ib tug ntev ntawm 10 mus rau 30 cm.
• Ntev (ntau tshaj ib tug Meter). Welded raws li medium-qhov loj qhov me pob qij txha, nrog qhov txawv tsuas yog hais tias lub xov tooj ntawm cov zajlus yuav muaj ntau.

Hom ntawm welds

Ib suam ntawm welds yog nqa tawm kuj los ntawm mounting hom. Muaj plaub hom kev sib txuas:

• taub qab;
• T-bar;
• ncej puab;
• angular.

Feem ntau hom

Thaum lub sij hawm taub qab coupling yog muab rau tus account lub thickness ntawm cov khoom. Qhov no tso cai rau koj mus cawm ib tug txiav txim ib feem ntawm cov khoom.

Taub qab tuav yog suav tias yog lub feem ntau nrov. Qhov no yog vim lub fact tias lub vuam txoj kev - lub ceev tshaj plaws thiab feem ntau yig.

T-Vuam. Nta thiab cov tswv yim

Rau no hom ntawm clutch yam ntxwv T-puab koom hlau cov khoom. Raws li nyob rau hauv cov taub qab sib koom tes, kev mloog yog them mus rau lub thickness ntawm cov hlau, nyob ntawm seb uas cov pob qij txha yog ib mog thiab ob mog.

Thov hom clutch, koj yuav tsum ua raws li cov lus qhia nram qab:

• Ua vuam ntawm tee coupling ob yam khoom coj txawv thicknesses, nws yog tsim nyog vuam teeb nyob rau hauv kev sib raug zoo rau cov khoom thicker kom lub kaum sab xis ntawm 60 degrees.
• Vuam ua hauj lwm yog yooj yim yog tias koj tso cov kev siv "nyob rau hauv lub nkoj." Xws li ib tug txoj hauj lwm ntawm lub workpiece yuav tshem tawm undercuts, tsis siav tej thaj chaw uas rau no hom ntawm clutch yog cov feem ntau tsis xws luag.
• Yog hais tias ib tug ib tug pass Vuam teeb yuav pab tsis tau, txij thaum lub puas feem tej zaum yuav nyob twj ywm, lawv yuav tsum rhaub ua vuam electrode oscillation.
• Cov T-pob qij txha thiab yuav kaw mog welding. Ua li no, siv cov vuam khoom Oineo Tronic Pulse, uas tso cai rau RW-brew.

overlap vuam

Lub hauv paus ntsiab lus ntawm no hom ntawm kev twb kev txuas muaj nyob rau hauv ib tug ob sab sib dho vuam cov khoom uas thickness yog tsis ntau tshaj 1 cm. Qhov no vuam yog thov qhov tsim nyog los mus tiv thaiv dej los ntawm uas nkag mus rau cov kis ntawm tus steel daim hlau. Lub leeg yog tsim los ntawm ob tug ua hauj lwm. Qhov no hom ntawm welded pob qij txha yog suav tias yog ntev thiab tsis yog yig, txij thaum lub chaw ua hauj lwm yuav tsum tau ntau cov ntaub ntawv.

angular tuav

Qhov no hom ntawm vuam yog siv rau pub ntxiv tshaj hlau khoom nyob rau hauv ib txoj hauj lwm perpendicular mus rau txhua lwm yam. Nyob rau hauv lub thickness ntawm daim ntawv ces kaum vuam yog tsiag ntawv los ntawm muaj los yog tsis tuaj kawm ntawv ntawm chamfered npoo. Yog hais tias tsim nyog, qhov no zoo ntawm kev twb kev txuas yog ua nrog rau qhov hauv cov khoom.

Daim ntawv welds

Classification welds mus rau lub txheej saum npoo sij peb hom:

• Pav ca. Pib nyob rau hauv dynamic thiab alternating load, vim hais tias cov nqaws (xws li concave) tsis muaj concentration ntawm kev nyuaj siab uas yuav ua rau cia li hloov thiab ua puas lub vuam tuav.
• Concave. Tswv pub weld concavity, tsis tshaj 0.3 cm. Txwv tsis pub concavity weld yog suav tias yog ntev li ntawm thiab yog xam raws li ib tug kho raws. Ntsuas qib ntawm concavity nyob rau hauv ib thaj chaw uas muaj tus loj tshaj deflection.
• Su nqaws. Tshwm sim los ntawm tsub zuj zuj ntawm ib tug loj npaum li cas ntawm solidified hlau thiab pom tau hais tias uneconomic. Tab sis nyob rau tib lub sij hawm, lub weld sib koom tes, muab ib tug convex leeg zoo li qub load dua lub compound nrog ib tug ca los yog concave weld. convexity zaub - qhov kev ncua deb ntawm tus nto ntawm tus niam txiv hlau mus rau lub siab tshaj plaws taw tes ntawm lub protrusion. Standard xam tau tias yog protuberances tsis tshaj 0.2 cm, ua nyob rau hauv lwm txoj haujlwm ntawm lub sab vuam thiab tsis ntau tshaj li 0.3 cm rau welding.

Ib suam ntawm welds rau txoj hauj lwm nyob rau hauv qhov chaw

Raws li qhov chaw kauj rau hauv qhov chaw muaj cov plaub hom pob qij txha, txhua tus uas muaj nws tus kheej cov yam ntxwv thiab tswv yim pom zoo rau welding:

• Lower nqaws. Nyob rau hauv cov kev nam yog cov feem ntau yooj yim. Vuam lub sab nqaws yog ua rau ib tug ca saum npoo nyob rau hauv lub hauv qab txoj hauj lwm. Qhov no txoj kev yog yus siab productivity thiab zoo. Qhov no yog vim ntau paaj tej yam kev mob rau lub welder. Hlau Rasplavlivaemy nws hnyav yog hais horizontally pov tseg welded da dej. Thaum lub sij hawm ua noj ua haus rau sab nqaws yooj yim mus ua raws li. Ua hauj lwm yog nqa tawm sai sai.
• Kab rov tav cov pob qij txha. Welded ib tug me ntsis nyuab me ntsis. Qhov teeb meem yog hais tias lub hlau melts nyob rau hauv tus ntawm nws qhov hnyav yuav loog mus rau lub sab ntug. Qhov no tej zaum yuav entail undercuts nyob rau hauv lub cheeb tsam ntawm lub sab sauv ntug.
• Vertical pob qij txha. Tebchaw yog lub txiaj ntsim ntawm hlau cov khoom teem nyob rau hauv ib ntsug dav hlau.
• Qab nthab pob qij txha. Qhov no vuam yog suav tias yog lub feem ntau nyuaj thiab lub luag hauj lwm. Yus ib tug tsawg kawg nkaus ntawm kev nplij siab. Thaum lub sij hawm vuam txoj kev utrudnyaetsya xaiv slags thiab roj cua. Nrog rau qhov no ua lag ua luam mus rau tiv tsis txhua leej txhua tus xav tau ib tug ntau ntawm kev, yog li ua li cas koj kom ntog ntawm lub ntsej muag ntawm lub slag yog tsis yooj yim loj hlob. Nws yog ib qho tseem ceeb mus soj ntsuam cov zoo thiab lub zog ntawm kev twb kev txuas.

Raws li denoted los ntawm lub welds thiab kev sib txuas?

Classification thiab los ntawm welds tau siv tshwj xeeb icons, cov kab thiab callouts. Lawv muab tso rau hauv los ua ke duab thiab cov qauv nws tus kheej. Ib suam ntawm welds thiab pob qij txha yog qhia, raws li tus qauv ntaub ntawv, nrog rau tshwj xeeb kab, uas tej zaum yuav mus li los yog tawg. Nruam xws pom welds, lub dashed - invisible.

Cim Weld muab tso rau hauv txee ntawm tus thawj coj (yog hais tias tus leeg yog nyob rau pem hauv ntej sab). Los yog, on qhov tsis tooj, nyob rau hauv lub txee, yog hais tias tus leeg yog situated rau cov rear. Nrog kev pab los ntawm lub icon qhia cov kev faib ntawm welds, lawv intermittence, kev pab rau welding feem.

Close rau loj icons ntxiv. Lawv muaj tom qab cov lus qhia:

• thau ntxiv dag zog rau weld;
• ntawm qhov chaw kho mob rau ib tus hloov mus rau lub hauv paus hlau thiab tiv thaiv kom txhob sagging thiab unevenness;
• ntawm kab tshaj li uas tus leeg (seb nws yog kaw).

Rau tib yam lug thiab qhov chaw ntawm cov qhua, muaj ib tug txheej txheem cim thiab kev uas yuav tsum tau. Yog hais tias muaj yog zoo tib yam nyob rau hauv kev tsim kho pob qij txha, ces nws yog ib qho zoo los muab rau tus serial tooj thiab muab faib ua tej pawg neeg, uas yog tseem rau lub yooj yim ntawm muab xov tooj. Tag nrho cov ntaub ntawv nyob rau hauv lub xov tooj ntawm cov pab pawg thiab pob qij txha yuav tsum tau teev nyob rau hauv lub normative ntawv.

ob leeg txoj hauj lwm

Classification weld leeg yog raws li nyob rau hauv txoj hauj lwm. Lawv yog:

• Unilateral. Yog tsim los ntawm vuam los xij, lub thickness ntawm cov uas tsis pub tshaj 0.4 cm.
• Muab ob npaug rau mog. Nws tshwm sim thaum ob tug mog vuam ntawm hlau los xij ntawm thickness 0.8 cm. Rau txhua compound nws yog pom zoo kom tawm 2-millimeter khoob, muab adhesion zoo.

tau flaws

Tsis xws luag thaum lub sij hawm vuam yuav tshwm sim vim excessively siab tam sim no thiab voltage ntawm lub arc. Nws kuj yuav lub txiaj ntsim ntawm kev manipulation ntawm cov electrodes. Classification uas tsis xws luag nyob rau hauv welds raws li lawv qhov chaw nyob:

• Internal. Rau lawv nrhiav kom tau cov txheej txheem yog siv, yog tswj: tsis puas qauv kev rhuav tseg kiag li los yog.
• Sab nrauv. Lawv yog yooj yim nrhiav tau los ntawm lwm xeem.

Vim rau kev ua txhaum ntawm lub vuam tej yam kev mob tshwm sim los ntawm ib tug tsis muaj kev txawj ntse, tsis muaj kev npaj ua hauj lwm ua los ntawm cov tsis ncaj ncees lawm ntsuam, tsis xws luag muab faib ua:

• Tsis muaj fusion. Nws zoo nkaus li nyob rau hauv lub zos uas tsis muaj fusion ntawm lub koom ntsiab. Cov kev kho raws tau nyob rau hauv nce kev nyuaj siab concentration thiab yuav txo tau ntawm lub leeg seem. Tus tsim khuam yog yus nrog cov uas tsis muaj zog thiab kev cia siab. tsis muaj fusion ua tej zaum yuav ib tug tsis muaj tam sim no, thiab vuam nyob rau hauv ceev hom.
• Undercut. Cov kev kho raws yog nyob rau hauv ib lub zos yuav txo tau ntawm lub thickness ntawm lub hauv paus hlau. Qhov teeb meem no tshwm sim nyob ze ntawm ib thaj tsam ntawm welds.
• Hlawv-los ntawm kev. Lub qhov khuam yog ntawm daim ntawv no muaj kab noj hniav nyob rau hauv lub weld. Nws tshwm sim vim cov to ntawm molten hlau los ntawm da dej ntawm welding. Hlawv-los ntawm kev - qhov no yog tsis tsim nyog kho raws, nws yuav tsum tau urgently kho.
• Nezavarenny kev ua qab yias los yog kev nyuaj siab. Nws tshwm sim vim hais tias cov arc lov thaum lub sij hawm mus kom ze rau qhov kawg ntawm lub leeg.
• Lub influx. Cov kev kho raws yog qhia nyob rau hauv wicking ntawm lub weld hlau nyob puag hlau tsis muaj fusion.

Cov ua tsis xws luag yuav ua tau txawv heev, tab sis lawv yog Attendance muaj peev xwm ntawm kev txo lub adhesion zog, ua hauj lwm muaj kev cia siab, neeg thiab lwj cov tsos ntawm cov khoom.
