Dab tsi yog qhov tsim nyog rau Vuam Automotive nyias daim hlau, Pulse Vuam lossis Nruam Vuam? Dab tsi yog Qhov Sib Txawv Ceev?

Pulse welding thiab nruam vuam txhua tus muaj lawv tus kheej cov yam ntxwv thaum vuam automotive nyias daim hlau. Feem ntau hais lus, mem tes vuam yog tsim nyog rau vuam tsheb nyias daim hlau. Cov hauv qab no yog ib qho kev ntsuam xyuas tshwj xeeb:

Yog vim li cas vim li cas pulse vuam yog tsim nyog

1. Me me tshav kub cuam tshuam cheeb tsam: Pulse welding yog ua los ntawm pulsed tam sim no, uas generates tshav kub thaum lub sij hawm mem tes kom yaj cov khoom thiab tsim ib tug solder sib koom. Thaum lub sij hawm pulse pause, lub tshav kub input ho txo. Qhov no tuaj yeem tswj tau cov cua sov kom raug, txo cov thermal cuam tshuam rau cov ntaub ntawv nyob ib puag ncig ntawm daim ntawv tsheb, txo qhov kev pheej hmoo ntawm deformation, thiab tswj kom zoo dua qhov raug thiab qhov zoo ntawm daim ntawv tsheb.

2. Zoo weld zoo: Pulse arc muaj lub zog nplawm ntawm lub pas dej molten, thiab qhov txias txias ntawm lub pas dej molten yog ceev, nrog lub sij hawm nyob rau hauv qhov kub thiab txias, ua rau cov weld hlau qauv zoo thiab tuaj yeem txo qhov tsis xws luag xws li pores thiab kab nrib pleb, thiab txhim kho kev ua haujlwm ntawm cov vuam.

3. Zoo arc stability: Thaum vuam tam sim no tsis tshua muaj, txoj kev vuam dav dav yog nquag rau arc drifting, thaum pulse vuam muaj qhov zoo arc nruj thiab ruaj khov, uas tuaj yeem ua kom ruaj khov ntawm cov txheej txheem vuam, tshwj xeeb tshaj yog tsim rau nyias phaj vuam.

Kev ntsuas ceev sib txawv

Qhov sib txawv ntawm cov mem tes welding thiab nruam vuam nyob rau hauv vuam automotive nyias daim hlau tsis muaj tus nqi ruaj khov thiab cuam tshuam los ntawm ntau yam xws li kev ua haujlwm ntawm cov khoom siv, cov yam ntxwv ntawm cov khoom siv, vuam tsis, thiab lwm yam. Qhov xwm txheej dav dav yog raws li hauv qab no:

• Pulse welding: Feem ntau hais lus, mem tes vuam cov ntaub ntawv vuam cov ntsiab lus ib los ntawm ib qho. Txawm hais tias qhov vuam ceev ntawm ib qho mem tes nrawm, nws yuav tsum muaj ntau lub pulses kom tiav ib qho vuam, thiab qhov vuam ceev kuj qeeb dua piv rau qhov txuas txuas ntxiv. Thaum vuam automotive nyias daim hlau, qhov ceev ntawm mem tes vuam yog feem ntau nyob ib ncig ntawm kaum ntawm centimeters mus rau ib meter ib feeb. Piv txwv li, nyob rau hauv ib co txheej txheem uas siv pulsed laser vuam rau vuam automotive nyias daim hlau nrog ib tug tuab ntawm tsawg tshaj li 1 hli, qhov vuam ceev yuav nyob ib ncig ntawm 30 mus rau 80 centimeters ib feeb.

• Nruam vuam: Nruam vuam yog cov txheej txheem ntawm tsis tu ncua outputting zog rau vuam, ua rau ib tug ntau coherent weld tsim thiab theoretically ceev vuam ceev. Thaum vuam automotive nyias daim hlau, yog tias siv txuas txuas laser vuam lossis lwm yam txheej txheem, qhov ceev yuav ncav cuag ib mus rau ob peb meters ib feeb. Piv txwv li, thaum siv high-power nruam laser vuam rau vuam 1-2 hli tuab automotive nplooj ntawv, qhov vuam ceev tuaj yeem ncav cuag li 1.5 mus rau 3 meters ib feeb.
