Lub hauv paus ntsiab lus ntawm cov khoom siv ntawm vuam feem ntau yog suav nrog ob txoj kev tseem ceeb: arc vuam thiab txhuam vuam.
Arc vuam
Arc vuam yog kom yaj lub electrode thiab workpiece los ntawm cov cua sov tsim los ntawm arc tawm, yog li kom ua tiav vuam. Cov txheej txheem tshwj xeeb yog raws li hauv qab no:
Arc tiam: lub electrode thiab workpiece yog ob lub electrodes, thiab ib qho arc yog tsim tawm thaum lawv nyob ze. Qhov kub ntawm lub arc yuav ua rau lub eleground thiab workpiece rau yaj hauv zos.
Qhuav vuam: qhov kub ntawm arc melts lub electrode thiab workpiece, thiab molten hlau ib weld tom qab txias kom ua tiav qhov chaw sib txuas.
HLUB VUAM
Kev txhuam cov vuam yog siv cov cua sov tsim los ntawm kev sib txhuam ntawm kev sib tiv tauj ntawm lub workpiece kom tsim cov khoom ua haujlwm yas, thiaj li ua tiav vuam. Cov txheej txheem tshwj xeeb yog raws li hauv qab no:
Kev sib txhuam cov cua sov tiam: ib qho ntawm cov haujlwm ua haujlwm yuav tsum tau welded yog clamped nyob rau hauv ib tug sib tig fixture, thiab lwm yam yog fixture tsiv. Lub rotating workpiece rotates rotect driven los ntawm lub cev muaj zog, thiab kev txav workpiece maj mam los ntawm kev ua ntawm lub zog ntawm axial.
Thaum tshav kub nce: Tom qab kev sib cuag thiab nias, qhov me me protrusions ntawm kev sib txhuam ua ke yog thawj zaug kev sib raug zoo thiab sheared, tsim kev sib tw ua cua sov. Raws li thaj chaw sib tiv tauj tiag tiag, qhov kev sib txhuam ua rau muaj kev nce qib zuj zus sai, thiab qhov kub ntawm kev sib txhuam convases.
Yas deformation: Raws li kev ua ntawm thermal ua kom muaj zog, kev txhuam sib txhuam yog maj mam them los ntawm ib txheej ntawm cov vixe vix pa taws. Nyob rau lub sijhawm no, kev sib txhuam tshav kub yog hloov mus ua yas deformation tshav kub nyob rau hauv lub vencellastic hlau txheej. Raws li lub sijhawm sib txhuam nce, qhov kub ntawm ob tog ntawm lub vuam sib tw maj mam nce, ua flash, thiab thaum kawg ua tiav vuam
