Vuam Methods rau Weld Studs

Muaj peb lub ntsiab arc vuam txheej txheem rauweld studs.

Thawj qhov yog ruaj khov-arc stud vuam, tseem hu ua arc stud vuam. Ib qho ruaj khov thiab txuas txuas hluav taws xob arc yog tsim los ntawmstudkawg thiab workpiece. Raws li lub tshav kub qhov chaw, lub arc tsim ib tug molten pas dej ua ke ntawm lub hauv paus cov ntaub ntawv ntawm lub workpiece, thiab lub caij no ua ib tug molten txheej thiab yas cheeb tsam ntawm lub stud kawg. Nyob rau hauv lub vuam phom, lub stud yog nias rau hauv lub molten pas dej ua ke los ntawm lub caij nplooj ntoos hlav quab yuam los yog lwm yam mechanical zog los ntawm rab phom. Ib feem los yog tag nrho cov hlau molten yog nyem tawm ntawm lub pas dej ua ke thiab ntws mus rau hauv cov ceramic ferrule ua zawj, tsim cov yas recrystallized los yog sib xyaw metallurgical sib koom nrog ob qho tib si recrystallization thiab recrystallization-theem transformation. Cov khoom siv hluav taws xob rau cov txheej txheem no feem ntau yog arc-welding rectifiers (tswj thiab tsis tswj tau) nrog cov yam ntxwv ntawm cov volt-ampere, vuam inverters lossis DC arc-welding generators. Lub arc tawm yog ruaj khov thiab tsis tu ncua, zoo ib yam li shielded hlau arc vuam.

Cov txheej txheem thib ob yog qhov tsis ruaj khov-arc stud vuam, uas yog capacitor-zog-storage stud welding, kuj hu ua capacitance discharge stud vuam. Nws siv lub txhab nyiaj capacitor ua lub zog rau kev tsim arc. Vuam yog ua tiav los ntawm instantaneous capacitor tawm ntawm lub stud kawg thiab workpiece. Capacitor tso tawm tsim ib qho kev tsis ruaj khov arc nrog kev hloov pauv sai ntawm arc voltage thiab vuam tam sim no, thiab cov txheej txheem vuam tsis tuaj yeem tswj tau. Studs siv nyob rau hauv cov txheej txheem no yuav tsum tau ib tug pre-fabricated taw tes taw rau ntawm qhov chaw ntawm lub stud kawg, yog li nws kuj yog hu ua ncov paug stud welding.

Qhov thib peb arc-based stud vuam txoj kev yog luv-cyclestud vuam, kuj hu ua short-time stud welding. Nws welding arc yog modulated nyob rau hauv tam sim no waveform. Cov txheej txheem welding muaj ob theem: ib tug pilot arc uas tsis tshua muaj tam sim no thiab lub ntsiab vuam arc nrog siab tam sim no. Nws yog ib lub sij hawm luv-term controllable arc stud-welding technology. Fais fab mov rau luv-lub voj voog stud welding feem ntau yog siv ob qho tib si fais fab kev sib txuas los muab lub zog sib txuas rau tus tsav arc thiab lub ntsiab vuam arc. Cov khoom sib txuas muaj xws li ob lub arc-welding rectifiers (tswj tau lossis tsis tswj tau), lossis lub rectifier sib phim nrog lub txhab nyiaj capacitor. Inverter-hom fais fab khoom siv tuaj yeem ua haujlwm yam tsis muaj kev teeb tsa dual-power parallel.
