Welded yeeb nkab txheej txheem

Electric Resistance Vuam Txheej Txheem (ERW)

Hlau Yeeb Nkab Hauv cov txheej txheem vuam tsis kam, cov kav dej yog tsim los ntawm kub, thiab txias tsim ntawm ib daim ntawv ntawm cov hlau tiaj tus hauv ib lub cylindrical geometry. Cov hluav taws xob tam sim no dhau los ntawm cov npoo ntawm lub tog raj kheej kom sov cov hlau thiab tsim ib daim ntawv cog lus ntawm cov npoo mus rau qhov chaw uas lawv raug yuam kom ntsib. Thaum lub sijhawm REG txheej txheem, cov khoom muab tub lim kuj tseem siv tau. Muaj ob hom kev tiv thaiv vuam: high-frequency welding thiab rotating contact wheel welding.

Qhov yuav tsum tau muaj rau cov khoom siv vuam ntau zaus yog los ntawm kev nyiam rau cov khoom siv tsawg zaus welded kom muaj kev xaiv sib koom ua ke, sib txuas sib txuas, thiab kev sib koom ua ke tsis txaus. Yog li ntawd, cov khoom tawg ntawm kev ua tsov rog tsawg zaus tsis siv los ua cov kav dej. Cov txheej txheem ERW high-frequency tseem siv hauv kev tsim cov raj. Muaj ob hom kev ua haujlwm siab REG. High-frequency induction welding thiab high-frequency contact welding yog hom high-frequency vuam. Nyob rau hauv high-frequency induction welding, lub vuam tam sim no kis mus rau cov khoom los ntawm ib tug coil. Lub coil tsis tuaj rau hauv kev sib cuag nrog cov yeeb nkab. Hluav taws xob tam sim no yog tsim nyob rau hauv cov khoom siv raj los ntawm cov hlau nplaum nyob ib puag ncig lub raj. Nyob rau hauv high-frequency hu welding, hluav taws xob tam sim no kis mus rau cov khoom los ntawm kev sib cuag ntawm lub sawb. Vuam lub zog yog siv ncaj qha rau cov yeeb nkab, ua rau cov txheej txheem ua haujlwm tau zoo. Txoj kev no feem ntau nyiam ua cov kav dej nrog cov kab loj loj thiab cov phab ntsa siab.

Lwm hom kev tiv thaiv vuam yog kev sib cuag lub log vuam txheej txheem. Thaum lub sij hawm tus txheej txheem no, hluav taws xob tam sim no kis tau los ntawm kev sib cuag log mus rau qhov chaw vuam. Lub log sib txuas kuj tsim lub siab xav tau rau vuam. Rotary contact welding feem ntau yog siv rau cov ntawv thov uas tsis tuaj yeem ua kom muaj kev cuam tshuam hauv cov yeeb nkab.

Electric Fusion Vuam Txheej Txheem (EFW)

Cov txheej txheem hluav taws xob fusion welding yog hais txog cov kab hluav taws xob electron vuam ntawm cov phaj hlau uas siv cov kev ua haujlwm siab ceev ntawm cov nqaj hlau electron. Lub zog muaj zog kinetic zog ntawm cov kab hluav taws xob hluav taws xob tau hloov mus rau hauv cov cua sov kom sov lub workpiece los tsim cov vuam seam. Qhov chaw weld kuj tuaj yeem kho cua sov kom ua rau pom tsis pom. Welded kav feem ntau muaj nruj dua qhov ntev dua li cov kav dej seamless thiab, yog tias tsim nyob rau hauv tib qhov ntau, raug nqi tsawg. Feem ntau yog siv rau vuam ntau yam hlau daim hlau los yog lub zog siab ceev vuam, hlau welded qhov chaw tuaj yeem ua kom sov sai rau qhov kub thiab txias, melting tag nrho cov hlau refractory thiab alloys.

Submerged Arc Vuam Txheej Txheem (SAW)

Submerged arc vuam yuav tsim ib qho arc nruab nrab ntawm cov hlau electrode thiab cov khoom ua haujlwm. Ib lub kwj deg yog siv los tsim cov roj thiab cov slag. Raws li lub arc txav mus raws seam, cov dej ntws ntau dhau raug tshem tawm los ntawm lub funnel. Vim hais tias lub arc yog tag nrho los ntawm flux txheej, nws yog feem ntau pom tsis tau thaum lub sij hawm vuam, thiab kub poob kuj tsis tshua muaj heev. Muaj ob hom submerged arc vuam txheej txheem: ntsug submerged arc vuam txheej txheem thiab muab kauv submerged arc vuam txheej txheem.

Nyob rau hauv longitudinal submerged arc vuam, longitudinal npoo ntawm steel daim hlau yog thawj beveled los ntawm milling los ua ib tug U zoo. Cov ntug ntawm U-puab daim hlau yog ces welded. Cov kav dej tsim los ntawm cov txheej txheem no yog raug nthuav tawm ua haujlwm kom ua rau muaj kev ntxhov siab sab hauv thiab tau txais ib qho kev ua kom zoo nkauj.

Nyob rau hauv kauv submerged arc vuam, weld seams zoo li lub helix nyob ib ncig ntawm cov yeeb nkab. Nyob rau hauv ob qho tib si ntawm longitudinal thiab kauv vuam txoj kev tib lub tshuab yog siv, qhov sib txawv tsuas yog cov kauv zoo li seams nyob rau hauv kauv vuam. Cov txheej txheem tsim khoom yog dov lub steel sawb kom cov kev taw qhia dov ua ib lub kaum sab xis nrog lub radial kev taw qhia ntawm lub raj, zoo li, thiab weld kom cov weld kab nyob rau hauv ib tug kauv. Lub ntsiab qhov tsis zoo ntawm cov txheej txheem no yog qhov tsis zoo ntawm lub cev qhov ntev ntawm cov yeeb nkab thiab qhov sib koom ua ke ntev dua uas tuaj yeem yooj yim ua rau muaj qhov tsis xws luag lossis tawg.
