Submerged arc vuam yog ib qho arc vuam nyob rau hauv flux txheej combustion txoj kev. Vuam arc nruab nrab ntawm cov hlau thiab cov vuam kub kub ntawm lub arc thiab arc vuam hlau xaus nyob ze ntawm lub hauv paus hlau thiab solder melts, txuas ntxiv pub cov hlau, thiab ua raws li ib qho kev sib tw, ib qho arc weld pas dej ua ke cov hlau raug tshem tawm kom vuam cov molten. solder yog solidified rau hauv lub plhaub npog qhov chaw ntawm lub weld slag, slag ntawm molten pas dej ua ke thiab weld hlau rau kev tiv thaiv arcing thiab lub pas dej ua ke los ntawm sab nraum cua intrusion.
Submerged arc vuam arc, xaim, xaim thiab ua haujlwm cuam tshuam xws li kev ua haujlwm feem ntau yog ua los ntawm tshuab, nws yog hu ua submerged arc vuam. SAW muaj qhov zoo hauv qab no: ① qib siab ntawm kev siv tshuab, rau cov vuam xav tau qib siab; ② vuam tam sim no, tuaj yeem txo qhov vuam zawj, kev siv vuam zoo; ③ tuaj yeem sib cais los ntawm molten solder hlau sib cuag nrog huab cua, tiv thaiv zoo, zoo weld zoo; ④ npog nrog arc hluav taws xob, kev ua haujlwm zoo dua. Qhov tsis zoo yog tias tsuas yog nyob rau hauv txoj hauj lwm tiaj tus vuam, cov khoom siv vuam thiab cov cuab yeej siv xav tau.
High-frequency welding mus rau high zaus tam sim no cua sov ntawm lub workpiece, thiab ces siv lub siab welding pob qij txha (saib daim duab) yog tsim. Ib tug high-frequency tam sim no yog concentrated nyob rau saum npoo ntawm tus neeg xyuas pib thiab ntws raws txoj kev ntawm tsawg inductance tshaj lub hauv paus ntsiab lus, tam sim no yuav concentrated cua sov ntawm lub workpiece nto yuav tsum tau welded, lub thermoplastic lub xeev mus txog, los yog ib feem ntawm lub xeev molten, extruding. cov hlau molten ntawm lub workpiece thiab nias cov hlau oxide, yog tsim los ntawm welded pob qij txha. High-frequency vuam siv ntau zaus ntawm 60 txog 500 kHz. High zaus kuj welding high zaus vuam cov ntsiab lus thiab ob lub high-frequency induction vuam.
① High Frequency Resistance Vuam: kev sib cuag nrog lub log los yog raws li ib tug sub-electrode high-frequency tam sim no nyob rau hauv lub workpiece, haum rau nruam longitudinal seam welded yeeb nkab thiab kauv lap seam vuam, boiler raj thiab fin heat exchanger kauv welded fin, sab nraud txoj kab uas hla yeeb nkab yuav ua tau 1200 hli thiab phab ntsa thickness ntawm 16 hli, ventral beam vuam electrode thickness 9.5 hli, siab productivity.
② high-frequency induction welding: ib txoj kab uas hla me me thiab cov phab ntsa thickness ntawm lub workpiece los ntawm induction cua sov coil yuav welded mus rau ib tug txheej txoj kab uas hla ntawm 9 hli thiab 1 hli nyias-walled raj. Feem ntau siv nyob rau hauv me me txoj kab uas hla longitudinal yeeb nkab seam welding thiab tooj dag kuj yuav siv tau girth weld, tab sis lub hwj chim noj yog ntau dua lub high-frequency kuj welding. Lub ntsiab tsis muaj feem cuam tshuam rau qhov zoo ntawm cov khoom siv vuam zoo yog lub zog muaj zog zaus, lub zog, lub zog ua haujlwm, lub vuam ceev thiab siab los ntawm kev nyem, electrode (los yog induction coil) thiab nyem chais. Cov khoom siv loj zaus fais fab mov, lub workpiece tsim apparatus thiab extrusion machinery. ruaj khov high-frequency welding zoo, tsim tau zoo thiab tus nqi qis. Rau high-efficiency tsis siv neeg ntau lawm kab, zus tau tej cov advanced txoj kev slit raj.
