Lub weld nyob rau hauv vuam?

Hauv qhov tshwj xeeb teb ntawm vuam, lo lus "Weld" tuav lub ntsiab lus thiab nruab nrab lub ntsiab uas tau dhau cov lus siv hom lus. Nws yog hais txog ob qho tib si tshwj xeeb cov txiaj ntsig thiab lub hom phiaj tseem ceeb ntawm cov txheej txheem vuam. To kev nkag siab tias tus weld yog nyob rau hauv vuam nws yuav tsum tshuaj xyuas nws cov ntsiab lus, nws cov qauv kev teeb tsa, thiab nws lub luag haujlwm hauv kev tsim cov pob qij txha ua haujlwm.
Hauv vuam, ib weld yog lub zog sib koom ua ke los ntawm fusing ob lossis ntau dua cov khoom siv (nrog lossis tsis muaj qhov ntxiv ntawm cov khoom siv. Qhov fusion tshwm sim ntawm lub interface ntawm cov ntaub ntawv, uas lawv tau muab rhaub rau hauv Molten lossis lub xeev yas, tso cai rau lawv cov atoms rau intermix. Thaum txias txias, qhov fused cheeb tsam solidifies rau hauv ib qho, cov qauv sib koom tes. Tsis zoo li ib ntus lossis cov kev sib txuas tshuab - Xws li cov ntsia hlau, lossis cov nplaum {4 4} { Qhov nyiaj sib khi no yog dab tsi muab weld nws lub zog thiab kev mus ib txhis, ua nws cov khoom siv hauv vuam.
Ib tus weld hauv vuam yog txhais los ntawm ntau tus tseem ceeb. Weld hlau yog cov khoom uas ua rau cov sib koom ua ke nws tus kheej; Nws yuav muaj melted cov khoom siv hauv paus, ntxiv muab cov khoom siv ntxiv, lossis kev sib txuas ntawm ob qho tib si. Lub fusion cheeb tsam yog thaj chaw uas cov khoom siv hauv paus thiab weld hlau sib tov, ua kom muaj kev sib koom ua ke ntawm kev sib koom tes thiab cov ntaub ntawv qub. Cov cua sov - be} cuam tshuam cheeb tsam (Baz) Ua ke, cov Cheebtsam no ua ib tus weld uas yuav tsum tau sib xyaw nrog cov khoom siv hauv paus los ua raws li ib chav.
Cov yam ntxwv ntawm cov weld zoo hauv vuam yog nruj me ntsis txhais tau. Ua ntej, nws yuav tsum ua kom tiav fusion fusion: Yuav tsum tsis muaj qhov khoob, tsis tiav kev nkag mus, lossis tsis muaj kev sib raug zoo ntawm Weld hlau thiab cov khoom siv hauv paus. Ib tus weld nrog cov tsis zoo fusion kev pheej hmoo tsis ua haujlwm nyob rau hauv lub nra, raws li kev sib koom tes yuav ua raws li qhov tsis muaj zog. Thib ob, nws yuav tsum pub dawb ntawm qhov tsis xws luag. Feem ntau qhov tsis txaus siab zoo li porosity (roj npuas daig hauv weld), tawg, los yog underall cov ntaub ntawv), yog cov qauv kev lag luam tsim lub zog ntawm lawv lub xub ntiag. Thib peb, ib weld yuav tsum phim lossis tshaj cov khoom siv tshuab ntawm cov khoom siv hauv paus, nrog rau corrosion lossis qaug zog, nyob ntawm daim ntawv thov.
Nyob rau hauv vuam xyaum, ib weld yog puab los ntawm kev xaiv vuam vuam, tsim qauv sib koom tes, thiab kev ua haujlwm tsis zoo. Piv txwv li, hauv Arc vuam, lub tshuab hluav taws xob ua kom sov rau cov khoom siv cua sov thiab muab tub lim rau hauv hluav taws xob, nrog rau weld noj ua cov electrode raws li kev sib koom tes. Hauv roj tungsten arc vuam (gtaw), tsis yog- Consumable tungsten elcsten elcsten elcsten elcsten The resulting weld's shape-such as a fillet weld (triangular in cross-section for joining perpendicular surfaces) or a butt weld (filling the gap between aligned edges)-is determined by the joint design, which in turn depends on the application's load requirements and material thickness.​
Ib tus weld hauv vuam tsis yog tsuas yog kev sib txuas ntawm lub cev; Nws yog lub hom phiaj kawg ntawm tag nrho cov txheej txheem vuam. Txhua kauj ruam hauv vuam - los ntawm kev npaj cov khoom siv (kev sib tsoo, kev sib tsoo, ua kom sov} Txawm hais tias nyob rau hauv cov txheej txheem steel vuam, qhov twg cov tsev yuav tsum muaj kev txhawb nqa txuas ntxiv, Weld yog qhov ua tiav kev ruaj ntseg, ruaj khov, thiab ua haujlwm sib koom ua haujlwm.
Hauv cov ntsiab lus, hauv vuam, ib txoj kev sib tw weld yog cov hlau me me sib koom ua ke los ntawm fusing cov khoom siv (thiab feem ntau muab cov khoom siv ua haujlwm thiab txias. Nws txhais tau los ntawm nws mus tas si, kev koom ua ke nrog cov khoom siv hauv paus, thiab kev ua raws li cov qauv zoo. Raws li cov tub ntxhais kawm tau tshwm sim ntawm vuam, ib weld hloov cov ntaub ntawv mus rau hauv cov qauv sib koom ua ke, ua rau kev tsim txhua yam ntawm txhua hnub muaj kev lag luam kev lag luam. Nyob rau hauv cov lus ntawm vuam, ib weld yog ob qho txiaj ntsig thiab lub hom phiaj- qhov kev sib txuas tseem ceeb uas ua rau cov khoom siv tes ua haujlwm.
