- Vuam tshav kub input
Nyob rau hauv qhov tseeb high-frequency ncaj seam steel yeeb nkab vuam txheej txheem, lub vuam fais fab siv ncaj qha txiav txim siab lub tshav kub input ntawm steel yeeb nkab vuam. Thaum cov xwm txheej sab nraud yog qhov tseeb thiab cov khoom siv hluav taws xob tsis txaus. Lub rhuab strip ntug tsis tuaj yeem ncav cuag qhov kub ntawm qhov vuam, tseem muaj cov qauv ruaj khov, yog li tsim cov vuam txias, thiab txawm tias tsis tuaj yeem fused.
Qhov fusion tsis tiav no feem ntau tshwm sim hauv qhov kev sim ua tsis tiav. Cov yeeb nkab tawg thaum lub sij hawm hydrotesting los yog weld tawg thaum lub sij hawm cov yeeb nkab ncaj yog ib qho teeb meem loj. Tsis tas li ntawd, weld tshav kub input tuaj yeem cuam tshuam los ntawm qhov zoo ntawm cov npoo npoo. Piv txwv li, thaum lub sawb muaj ib tug burr ntawm ntug, lub burr ua rau ib tug spark ua ntej nws nkag mus rau hauv lub weld sib koom ntawm lub extrusion yob, uas ua rau ib tug poob ntawm weld zog thiab txo cov cua sov input, uas ua rau ib tug tsis tiav yaj los yog txias weld. Thaum tshav kub kub input siab dhau lawm, lub ntug ntawm daim kab xev cua sov tshaj qhov vuam kub, uas ua rau overheating los yog txawm kub heev, lub weld tawg nyob rau hauv siab, thiab tej zaum cov molten hlau splatters tsim qhov vim weld rupture.
- Vuam siab (txo)
Vuam siab yog ib qho tseem ceeb heev nyob rau hauv cov txheej txheem vuam, tshwj xeeb tshaj yog thaum lub sawb ntug yog rhuab mus rau ib tug tej yam vuam kub. Cov hlau atoms ua ke nrog ib leeg los tsim cov weld seam nyob rau hauv lub squeezing siab ntawm extrusion rollers. Vuam siab cuam tshuam lub zog thiab toughness ntawm weld. Yog tias qhov kev siv vuam siab tsawg dhau. Weld npoo tsis tuaj yeem yaj tag nrho, cov weld residual hlau oxides tsis tuaj yeem tawm mus rau hauv kev sib koom ua ke, ua rau txo qis hauv lub zog tensile ntawm lub vuam, qhov vuam yog yooj yim tawg tom qab kev ntxhov siab. Tau kawg, tib yam, yog tias qhov vuam siab thov hauv cov txheej txheem vuam siab dhau lawm, feem ntau ntawm cov hlau mus txog qhov kub ntawm vuam yuav raug nyem. Qhov no tsis tsuas yog txo lub zog thiab toughness ntawm weld, tab sis kuj ua rau muaj qhov tsis xws luag xws li sab hauv thiab sab nraud burrs lossis lap welds.
Vuam siab feem ntau yog ntsuas thiab txiav txim los ntawm qhov sib txawv ntawm txoj kab uas hla ntawm lub raj ua ntej thiab tom qab nyem yob thiab qhov loj thiab cov duab ntawm cov burr.
- Cov nyhuv ntawm welding nyem ntawm cov duab ntawm burr
Vuam extrusion yog loj heev, spatter, extrusion ntawm molten hlau, burr, molten hlau ntawm ob sab ntawm lub weld flip; extrusion me me heev, yuav luag tsis muaj spatter, burr me me, pawg. Thaum tus nqi ntawm extrusion yog nruab nrab, lub extruded burr yog ntsug, thiab qhov siab feem ntau tswj ntawm 2.5 ~ 3 hli. Yog hais tias tus nqi ntawm welding extrusion yog tswj, lub kaum sab xis ntawm cov hlau ntws kab ntawm cov weld yog qhov yooj yim symmetrical nce thiab nqis, nrog lub kaum sab xis ntawm 55 ~ 65.
