Mu by’amakolero ag’omulembe, .abaweesi b’ebifo aba frequency eya wakatizifuuse ebyuma ebikulu mu makolero nga okukola mmotoka, okukola ebyuma by’omu maka, n’okulongoosa ebyuma olw’okukola obulungi era okutuufu mu kuweta. Naye, abaddukanya bangi bakyalina ebibuuzo ku ngeri abaweta mu bifo eby’omu makkati gye bakolamu, naddala ku bikwata ku nkyukakyuka yaabwe ey’akaseera kano-okusingira ddala, mu mutendera ki ogw’enkola y’okuweta akaseera kano akali ku ntikko. Ensonga eno tekwata ku mutindo gwa welding gwokka wabula era ekosa butereevu enkozesa y’amaanyi g’ebyuma n’obulamu bwayo. Ekiwandiiko kino kijja kuwa okwekenneenya okw’obuziba-ku nkola y’enkyukakyuka eriwo kati mu baweesi b’ebifo ebya frequency eya wakati okuva mu misingi gyombi egy’ekikugu n’endowooza z’enkola ey’enkola.
I. Enkola y’emirimu n’engeri eziriwo kati ez’abaweesi b’ebifo aba medium Frequency
- Abaweeza mu bifo eby’enjawulo (medium frequency spot welders) bakozesa tekinologiya wa medium frequency inverter okukyusa amaanyi ga AC aga utility (50/60Hz) mu masannyalaze ga DC aga frequency eya wakati (mu ngeri entuufu 1kHz-4kHz), oluvannyuma ne gakyusibwa ne gafulumya current enkulu. Bw’ogeraageranya n’ebyuma ebiweta AC eby’ennono, ebifulumizibwa byabwe mu kiseera kino biba binywevu, sipiidi y’okuddamu eba ya mangu, era zisobozesa okufuga obulungi amaanyi g’okuweta.
- Mu nkola eno, enkyukakyuka eriwo kati mu aomuwemba w’ekifo kya frequency eya wakatitesaasaanyizibwa mu ngeri y’emu wabula etereezebwa mu ngeri ya maanyi okusinziira ku mutendera gw’okuweta. Enkola enkulu esobola okwawulwamu emitendera esatu:
- Omutendera gw'okusika:Electrodes zikwatagana ne workpieces, nga zissa puleesa okumalawo ebituli. Akasannyalazo ku mutendera guno mutono nnyo oba wadde ziro.
- Omutendera gwa Weld:Ebisannyalazo biweebwa amaanyi, era akasannyalazo kalinnya mangu okutuuka ku muwendo ogwateekebwawo okutuuka ku kuyungibwa kw’ebyuma.
- Kuba Omudaala:Akasannyalazo kasalibwako, naye puleesa ekuumibwa okukakasa nti weld nugget ekaluba.
- Ekikulu Ekimaliriziddwa:Ekiseera kino kituuka ku ntikko mu kiseera ky’...weld stage, era obudde buba bumpi nnyo (mu ngeri entuufu milisekondi ntono okutuuka ku milisekondi ebikumi bitono). Akasannyalazo kano aka waggulu ak’akaseera katono y’embeera enkulu ey’okukola ekikuta kya weld eky’omutindo ogwa waggulu-.
II. Enkola y’okutondebwa n’ensonga ezikwata ku Peak Current
- Mu kiseera ky’okulongoosebwa kwa aomuwemba w’ekifo kya frequency eya wakati, okubeerawo kwa peak current kukwatagana nnyo n’ensonga zino wammanga:
Ebintu Ebikozesebwa n’Ebyetaagisa mu Welding
- Obuziyiza bw’ekyuma:Ebintu ebirina obuziyiza obw’amaanyi (okugeza, ekyuma ekitali kizimbulukuse) bikola ebbugumu lingi wansi w’akasannyalazo ke kamu, ekiyinza okwetaagisa ekiseera ekitono eky’akasannyalazo ak’oku ntikko okwewala okubuguma ennyo.
- Obugumu bw’Empapula:Ebikozesebwa ebinene byetaaga akasannyalazo akasingako okuyingira mu layeri z’ebyuma. Okugeza, okuweta ekipande ky’ekyuma ekya mm 2 kiyinza okwetaagisa akasannyalazo ak’oku ntikko akasukka 10kA, ate okuweta ekipande ekigonvu kuyinza okwetaaga 2kA-5kA zokka.
Ensengeka z’Ebyuma Parameter
- Preset Current n'Ekiseera:Abaddukanya emirimu balina okuteekawo peak current n’obudde bwayo okusinziira ku byetaago by’enkola. Okugeza, mu welding y’omubiri gw’emmotoka, peak current eyinza okuteekebwa ku 8kA nga emala 20ms.
- Amaanyi ga Busannyalazo:Amaanyi agatali gamala gayongera ku buziyiza bw’okukwatagana, nga kyetaagisa kasasiro ow’amaanyi okusobola okuliyirira; empalirizo esukkiridde eyinza okumenya ekintu ekikolebwa, ne kyetaagisa akasannyalazo akatono.
- Engeri z’okuddamu okw’amaanyi
Inverter ya medium frequency spot welder esobola okuddamu enkyukakyuka za current mu 1ms, okukakasa okulinnya amangu okutuuka ku ntikko eyateekebwawo mu kiseera ky’omutendera gwa weld. Akasannyalazo kano aka waggulu ak’akaseera kakuŋŋaanya amasoboza okusaanuusa ekyuma ate nga kakendeeza ku kitundu ekikoseddwa ebbugumu-n’okuziyiza okukyukakyuka kw’ekintu ekikolebwa.
III. Ebiteeso by’emirimu ku kulongoosa Peak Current
Okusobola okukozesa mu bujjuvu omulimu gwa aomuwemba w’ekifo kya frequency eya wakati, abaddukanya emirimu balina okufaayo ku nsonga zino wammanga ez’omugaso:
Okukwatagana okutuufu okwa Parameters z’Enkola
- Laga ekipimo ky'ekiseera ekiriwo-eky'ebintu eby'enjawulo nga oyita mu kugezesa. Okugeza, okuweta aluminiyamu kyetaagisa "high current, short time" mode, ate ebyuma ebikoleddwa mu galvanized byetaaga ekiseera ekiwanvu eky'okusika okukendeeza ku surface oxidation.
- Kozesa enkola z’okulondoola omutindo gw’okuweta (okugeza, okuzuula obuziyiza obw’amaanyi) okuwa okuddamu kw’ekiseera ekituufu-ku oba akasannyalazo ak’oku ntikko katuukana n’omutindo.
Okufuga Embeera ya Electrode
- Bulijjo oyoza ensonga z’obusannyalazo okwewala okweyongera okuziyiza okukwatagana okuva mu layeri za okisayidi oba obucaafu, ekiyinza okuvaako okulinnya mu ngeri etaali ya bulijjo mu bwetaavu obuliwo kati.
- Kozesa dizayini z’obusannyalazo obunyogozeddwa amazzi-okuziyiza ekintu ky’obusannyalazo okugonvuwa wansi w’ebbugumu eringi, ekikosa okutebenkera kwa puleesa.
Okuddaabiriza n’okupima ebyuma
- Buli mwezi kebera enkola ya insulation ya modules za inverter ne transformers okukakasa nti current output entuufu.
- Kaliba sensa za kasasiro okuziyiza okuva ku ntikko yennyini okuva ku muwendo ogwateekebwawo olw’ensobi mu kupima.
IV. Obulabe n’Ebiziyiza eri Abnormal Peak Current
Singa akasannyalazo ak’oku ntikko aka aomuwemba w’ekifo kya frequency eya wakati kifuuka ekitafugibwa, kiyinza okuleeta ebizibu bino wammanga:
- Weld Okwokya Okuyitiridde:Amasannyalaze agasukkiridde oba okumala ebbanga eddene ennyo kireeta ebyuma okusaanuuka ekisusse, ekivaako ebituli oba enjatika.
- Ebyuma Okwambala:Okukola okutikka okusukkiridde obutasalako kikendeeza ku bulamu bwa inverter era kyongera ku ssente z’okuddaabiriza.
- Kasasiro w’amasoboza:Amasannyalaze ag’oku ntikko agateetaagisa lyongera ku nsaasaanya y’amasannyalaze, kikosa nnyo okufulumya okw’amaanyi-.
Ebigonjoolwa:
- Yanjula enkola z’okufuga okukyusakyusa (adaptive control algorithms) okutereeza akasannyalazo mu ngeri ey’amaanyi okusinziira ku mbeera z’ekintu ekikolebwa.
- Teeka emirimu gya alamu ya threshold eriwo kati okusalako amangu enkola z’okuweta ezitali za bulijjo.
Mu bufunzi
Peak current ya medium frequency spot welder ebeera mu mutendera gwa weld, era obunene bwayo n’obudde bwayo bye bisalawo butereevu omutindo gw’okuweta. Nga bateekawo mu ngeri ya ssaayansi ebipimo n’okulabirira obulungi ebyuma, amakampuni tegasobola kukoma ku kulongoosa makungula ga bikozesebwa wabula n’okukendeeza ku masannyalaze agakozesebwa n’ebisale. Nga enkulaakulana ya tekinologiya w’okufuga mu ngeri ey’amagezi, okufuga okw’omu maaso okuliwo kati muabaweesi b’ebifo aba frequency eya wakatiejja kufuuka entuufu, okwongera okutumbula amakolero okutuuka ku bulungibwansi n’okuyimirizaawo.
