Qhov cuam tshuam ntawm tam sim no rau cov cua sov ntawm nruab nrab-Frequency DC Spot Vuam Tshuab

Nyob rau hauv lub ntiaj teb no ntawm welding technology, meej tswj ntawm ntau yam tsis yog ib qho tseem ceeb kom ua tau zoo welds. Ib qho ntawm cov tsis tseem ceeb no yog tam sim no, uas ua lub luag haujlwm tseem ceeb hauv cov txheej txheem cua sov ntawm nruab nrab zaus DC qhov chaw vuam tshuab. Nyob rau hauv tsab xov xwm no, peb yuav delve rau hauv lub zog ntawm tam sim no ntawm cov cua kub yam ntxwv ntawm cov cav tov.

Medium-frequency DC chaw vuam tshuab yog dav siv nyob rau hauv ntau yam lag luam vim lawv efficiency thiab precision. Cov tshuab no tsim cov welds muaj zog thiab ruaj khov los ntawm kev tsim cov cua sov ntawm qhov chaw vuam. Cov txheej txheem cua sov yog nyob ntawm qhov tam sim no muab rau cov vuam electrodes.

1. Tam sim no Magnitude:

   Qhov loj ntawm qhov tam sim no dhau los ntawm cov vuam electrodes ncaj qha cuam tshuam rau tus nqi ntawm cov cua sov tsim. Cov hluav taws xob siab dua ua kom muaj cua sov ntau dua, uas tuaj yeem ua tau zoo thaum vuam cov ntaub ntawv tuab. Txawm li cas los xij, ntau dhau tam sim no tuaj yeem ua rau overheating thiab ua rau cov khoom puas tsuaj.

2. Lub sijhawm tam sim no:

   Lub sijhawm uas tam sim no ntws los ntawm cov vuam electrodes yog lwm qhov tseem ceeb. Lub sijhawm tam sim no ntev dua tso cai rau cov cua sov ntau dua ntawm cov ntaub ntawv, uas tuaj yeem ua tau zoo rau kev ua tiav cov ntawv cog lus muaj zog. Hloov pauv, lub sijhawm luv luv yog tsim los tiv thaiv kev kub ntxhov ntau dhau hauv cov ntaub ntawv muag.

3. Pulse Current vs. Continuous Current:

   Qee qhov nruab nrab zaus DC qhov chaw vuam tshuab siv cov mem tes tam sim no, thaum lwm tus siv tam sim no txuas ntxiv. Pulse tam sim no tuaj yeem muab kev tswj xyuas meej ntawm cov cua sov siv thiab txo qhov kev pheej hmoo ntawm overheating. Nruam tam sim no, ntawm qhov tod tes, feem ntau yog xaiv rau cov ntawv thov uas xav tau vuam ceev thiab cua sov zoo ib yam.

4. Tam sim no Waveform:

   Cov duab ntawm qhov tam sim no waveform, xws li square lossis triangular, tuaj yeem cuam tshuam rau cov txheej txheem cua sov. Cov waveforms sib txawv faib cov cua sov sib txawv thoob plaws qhov chaw vuam, cuam tshuam rau qhov kawg weld qhov zoo thiab lub zog.

5. Kev txiav txim siab ntawm cov khoom siv:

   Hom thiab tuab ntawm cov ntaub ntawv uas tau welded ua lub luag haujlwm tseem ceeb hauv kev txiav txim siab qhov kev pom zoo tam sim no. Qee cov ntaub ntawv xav tau cov dej ntws ntau dua rau cov cua kub zoo, thaum lwm tus tuaj yeem raug puas tsuaj yog tias raug tam sim no ntau dhau.

6. Txias Mechanisms:

   Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias thaum lub sij hawm tam sim no tseem ceeb heev rau cua sov, cov tshuab cua txias yog qhov tseem ceeb sib npaug los tiv thaiv cov khoom siv los yog kev puas tsuaj. Kev tswj kom zoo ntawm cov tshuab cua txias kom ntseeg tau tias cov vuam khov kho kom raug.

Hauv kev xaus, qhov cuam tshuam ntawm tam sim no ntawm cov txheej txheem cua sov ntawm nruab nrab zaus DC qhov chaw vuam tshuab yog qhov tsis lees paub. Los ntawm kev ua tib zoo tswj qhov tam sim no qhov loj, lub sijhawm, waveform, thiab xav txog cov khoom siv welded, cov tuam ntxhab thiab cov welders tuaj yeem ua tiav qhov tseeb, zoo welds. Nkag siab txog cov xwm txheej no thiab lawv qhov kev sib cuam tshuam yog qhov tseem ceeb rau kev ua kom zoo dua cov txheej txheem vuam hla ntau yam kev siv thiab kev lag luam.
