Vuam hom bai txoj kev:
1. Electrode arc vuam:
Txujci du-fais dao arc vuam txoj kev siv phau ntawv vuam electrode zhi. Qhov ruaj khov hlawv arc tsim nruab nrab ntawm cov vuam txuas thiab cov hlau txuas yog siv los ua tus vuam vuam txuas thiab lub weldment kom tau txais qhov ruaj khov ntawm qhov txuas ua ke. Nws belongs rau roj-slag sib koom tes tiv thaiv.
Lub ntsiab tseem ceeb-hloov chaw ua haujlwm; kev sib dhos tsawg yuav tsum tau welded; ntau cov khoom siv weldable hlau; qis vuam tsim tau; muaj zog dependence ntawm weld zoo (nyob ntawm tus welder' s kev khiav hauj lwm muaj thiab kev ua haujlwm ntawm chaw).
Daim ntawv thov-siv dav hauv nkoj tsim, nkoj kub hnyiab thiab lub nkoj siab, lub tshuab ua khoom, kev tsim vaj tsev, khoom siv tshuaj thiab lwm yam lag luam tsim thiab txij nkawm. Haum rau vuam ntawm ntau cov ntaub ntawv hlau, ntau yam tuab, thiab ntau yam qauv duab (hauv qhov hais saum toj saud kev lag luam).
2. Xa cov arc vuam (tsis siv neeg vuam):
Ntsiab Cai-Lub arc hlawv nyob hauv qab txheej flux. Cov tshav kub ua los ntawm arc hlawv ntawm lub vuam hlau thiab cov hlau txuas yog siv los yaj cov vuam hlau, flux, thiab cov khoom siv hauv paus (weldwork) los ua lub weld. Nws yog kev tiv thaiv slag.
Lub ntsiab nta-cov khoom lag luam siab; weld zoo; tus nqi qis vuam tus nqi; kev ua haujlwm tau zoo; nyuaj rau weld nyob rau hauv qhov chaw; high quality yuav tsum tau rau weldment los ua ke; tsis tsim rau vuam daim hlau nyias nyias (thaum vuam tam sim no tsawg dua 100A, arc stability tsis zoo) thiab tsis siv neeg hlau ntev.
Daim ntawv thov-dav siv hauv nkoj tsim, nkoj txaij, txuas hniav, tshuab hoisting thiab kev siv tshuab ua xim hlau. Submerged arc vuam tuaj yeem siv rau tag nrho cov hlau txuas uas nws lub qhov txuas tuaj yeem khaws cia rau hauv kab rov tav lossis nws qhov kev txiav tsis sib haum yog tsis loj. Lub rooj tsavxwm tuab yuav tsum muaj ntau dua 5 hli (kom tsis txhob hlawv dhau los). Vuam cov txheej txheem steel, tsis tshua muaj alloy qauv hlau, stainless hlau, tshav kub-resistant hlau, puas hlau, thiab lwm yam.
3. Cov pa roj carbon dioxide tiv thaiv vuam (tsis siv neeg lossis ib nrab tsis siv neeg vuam):
Lub hauv paus ntsiab lus: Kev ua cov roj ntsha electrode arc vuam txoj kev siv cov pa roj carbon dioxide uas yog cov neeg ua haujlwm tiv thaiv. Nws yog kev tiv thaiv roj. Lub ntsiab nta-cov khoom lag luam siab; tus nqi qis vuam tus nqi; kev cuam tshuam vuam me me (arc cua sov siab); siab vuam zoo; cov haujlwm yooj yim; tus nqi siab tshaj plaws; nyuaj rau weld nrog AC zog; tsis zoo cua tsis kam; tsis tuaj yeem txuas nws yooj yim oxidized cov xim muaj hlau zoo nkauj.
4. MIG / MAG vuam (Melting inert gas / active gas shielded vuam):
MIG welding lub hauv paus ntsiab lus-tus qauv arc vuam txoj kev siv cov roj inert uas yog cov roj thaiv thiab vuam hlau ua cov hluav taws xob melting. Cov roj av npog feem ntau yog argon lossis helium lossis lawv sib xyaw. MIG siv cov roj inert, MAG ntxiv me me ntawm cov roj yam nquag, xws li cov pa oxygen, carbon dioxide, thiab lwm yam rau cov roj inert.
5. TIG vuam (vias roj inert gas tiv thaiv vuam)
Lub hauv paus ntsiab lus —— Nyob rau hauv kev tiv thaiv inert gas, lub hauv paus hlau thiab muab tub lim hlau tau yaj los ntawm arc tshav kub uas tsim los ntawm tungsten electrode thiab lub weldment (los yog tsis muaj cov muab tub lim hlau) ua lub vuam sib dhos. Lub electrode tsis yaj thaum vuam.
6. Ntshav arc vuam
Lub hauv paus ntsiab lus —— Ntseeg siab rau cov kev txwv kev cuam tshuam ntawm lub taub dej txias ntawm lub nkoj, cov txheej txheem tau txais lub zog hluav taws xob ntau dua plasma arc vuam.
