Medium frequency inverter spot welding machines anoshandiswa zvakanyanya mumaindasitiri akasiyana siyana nekuita kwavo kushanda nesimba mukujoinha zvinhu zvesimbi. Nekudaro, senge chero imwe nzira yewelding, nzvimbo welding uchishandisa michina iyi inogona kusangana nezvimwe zvinhu zvinokanganisa kunaka uye kuvimbika kwewelds. Ichi chinyorwa chine chinangwa chekukurukura mamwe matambudziko akajairika anogona kumuka panguva yewelding ine yepakati frequency inverter michina uye zvinogoneka mhinduro kuzvigadzirisa.
- Kusakwana Weld Penetration: Imwe yenyaya dzakajairika mukupinza welding haina kukwana weld kupinda, uko weld nugget inotadza kupinda zvizere mukati meiyo workpiece. Izvi zvinogona kukonzerwa nezvinhu zvakadai sekusakwana kwe electrode kudzvanywa, kusarudzwa kwehukobvu hwezvinhu zvisina kufanira, kana zvimiro zvewelding zvisina kunaka. Kuti ugadzirise nyaya iyi, zvakakosha kuve nechokwadi chakakodzera electrode kudzvanywa, optimize welding paramita (ikozvino, nguva, uye kusvina nguva), uye sarudza yakakodzera electrode zvinhu uye saizi yechishandiso chakapihwa.
- Weld Spatter: Weld spatter inoreva kusaswa kusingafadzi kwesimbi yakanyungudutswa panguva yewelding. Inogona kukonzera kusvibiswa kweweld, kushata aesthetics, uye kukuvara kunogona kuitika kune zvakatenderedza zvikamu. Weld spatter inowanzokonzerwa nepamusoro welding currents, isina kukodzera electrode tip geometry, kana kusakwana kwehutsanana hwebasa rekushanda. Kuti uderedze weld spatter, optimize welding parameters, kuchengetedza yakakodzera electrode tip mamiriro, uye kuve nechokwadi chakaringana kugadzirira kwepamusoro (kuchenesa uye kuchenesa) kweiyo workpiece kwakakosha.
- Electrode Wear: Kudzokororwa kushandiswa kwemaelectrodes munzvimbo yewelding kunogona kutungamira mukupfeka kwe electrode, zvichikonzera shanduko mu electrode geometry uye kuderera kwekuita kwewelding. Kuwedzerwa kwe electrode kupfeka kunogona kukanganisa kuwirirana uye kunaka kwewelds. Kugara uchiongorora uye kugadzirisa maelectrodes, akadai sekugadzirisa kana kutsiva maelectrode akasakara, zvinodiwa kuti ive nechokwadi chekushanda kwakakwana uye kuwedzera hupenyu hwavo.
- Weld Cracks: Weld cracks inogona kuitika nekuda kwezvinhu zvakadai sekunyanya kupisa kupisa, kusakwana kwekugadzirira zvinhu, kana kusarongeka kwewelding. Aya makatsemuka anogona kukanganisa kurongeka kweiyo weld joint. Kuti udzivise kutsemuka kweweld, zvakakosha kudzora kupinza kwekushisa kwewelding, kuve nechokwadi chekuchenesa kwakakodzera kwezvinhu uye kubatana-up, uye kuteedzera kutevedzana kwewelding kwakakodzera (sekuchinjisa mativi) kugovera kushushikana kwekupisa zvakaenzana.
- Kusapindirana Weld Hunhu: Kusapindirana weld mhando inogona kuverengerwa kune akasiyana zvinhu, kusanganisira kusiyanisa kwezvinhu zvenyama, electrode misalignment, kana kusakwana kwemuchina calibration. Kuti uwane inopindirana weld mhando, zvakakosha kushandisa zvinowirirana uye zvemhando yepamusoro zvinhu, kunyatso gadzirisa maelectrode, kugara uchigadzirisa muchina, uye kuitisa nguva nenguva yekutarisa uchishandisa nzira dzisiri dzekuparadza dzekuyedza.
Mhedziso: Spot welding ine yepakati frequency inverter michina inogona kusangana nenyaya dzinoverengeka dzinokanganisa huwandu hwese weld uye kuita. Kunzwisisa aya matambudziko akajairwa uye kushandisa mhinduro dzakakodzera kwakakosha kuti uwane akavimbika uye emhando yepamusoro nzvimbo welds. Nekugadzirisa nyaya dzakaita senge kusakwana kwekupinda, weld spatter, kupfeka electrode, weld cracks, uye kusawirirana weld quality, vashandisi vanogona kukwidziridza nzira yewelding uye kuona mhedzisiro inogutsa mukushandisa kwavo. Kugara uchigadzirisa, kuomerera kune welding nhungamiro, uye kuenderera mberi kwekutarisa kweiyo welding process ndiyo kiyi yekukunda izvi zvinonetsa uye kuwana akabudirira nzvimbo welds.
