Tlhahlobo ea Boleng ba Spot Weld Mechineng ea Welding ea Medium Frequency Inverter Spot

Boleng ba li-welds tse hlahisoang ke mechini ea welding ea frequency inverter spot welding bo bohlokoa haholo liindastering tse fapaneng. Sengoliloeng sena se ikemiselitse ho buisana ka mekhoa ea tlhahlobo e sebelisetsoang ho lekola boleng ba li-welds le ho netefatsa ho latela litekanyetso le litlhaloso tse lakatsehang.

1. Tlhahlobo ea Pono: Tlhahlobo ea pono ke mokhoa o atileng haholo le oa pele oa ho lekola boleng ba li-weld:
   • Lekola mefokolo e bonahalang joalo ka fusion e sa fellang, mapetsong, kapa litlolo tsa molao tsa weld nugget.
   • Lekola chebahalo ea tjheseletsa, ho kenyeletswa boholo ba yona, sebopeho, le ho tshwana.
2. Teko e sa Senyeheng (NDT): Mekhoa ea NDT e sebelisoa ho lekola boleng ba weld ntle le ho senya weld ka boeona:
   • Ultrasonic Testing (UT): E sebelisa maqhubu a molumo a phahameng-frequency ho lemoha mefokolo ea ka hare kapa li-discontinuities ka har'a weld, tse kang li-voids kapa ho hloka fusion.
   • Tlhahlobo ea Radiographic (RT): E kenyelletsa tšebeliso ea mahlaseli a X-ray kapa mahlaseli a gamma ho nka setšoantšo sa weld le ho lemoha mefokolo leha e le efe kapa ho se lumellane.
   • Teko ea Magnetic Particle (MT): E lemoha mefokolo e kaholimo kapa e haufi le bokaholimo ka ho sebelisa likaroloana tsa makenete ho weld le ho shebella boitšoaro ba tsona tlasa matla a khoheli.
   • Teko ea Dye Penetrant Testing (PT): E sebelisa mokelikeli o mebala-bala kapa dae ho cheselle, e kenang ka har'a mefokolo e robehileng ebe e bonahala ha e hlahlojoa.
3. Teko ea Mechini: Liteko tsa mochini li etsoa ho lekola matla le bots'epehi ba li-welds tsa matheba:
   • Teko ea Tensile Shear: E lekanya matla a hlokahalang ho arola mehlala e cheselitsoeng, ho lekola matla a ho kuta a weld.
   • Teko ea Peel: E lekola khanyetso ea weld ho matla a ho ebola, haholo-holo a bohlokoa bakeng sa li-welds tsa lap joint.
   • Cross-Sectional Analysis: E kenyelletsa ho seha le ho hlahloba karolo e fapaneng ea weld ho hlahloba lintlha tse kang boholo ba nugget, sebaka sa fusion, le sebaka se amehileng ke mocheso.
4. Tekanyo ea Resistance ea Motlakase: Tekanyo ea ho hanyetsa motlakase hangata e sebelisoa ho lekola boleng ba li-welds tsa matheba:
   • Contact Resistance: E lekanya khanyetso ho pholletsa le lenonyeletso la weld ho netefatsa conductivity e nepahetseng ea motlakase.
   • Nugget Resistance: E khetholla ho hanyetsa ka nugget ea weld, e ka bontšang ho lekana ha fusion le botšepehi.

Ho lekola boleng ba li-welds ka har'a mechini ea welding ea frequency inverter spot welding ho bohlokoa ho netefatsa boits'oaro le ts'ebetso ea sebopeho. Tlhahlobo e bonoang, tlhahlobo e sa senyeheng, tlhahlobo ea mochini, le tekanyo ea ho hanyetsa motlakase ke mekhoa ea bohlokoa ea ho lekola boleng ba weld. Ka ho sebelisa mekhoa ena ea tlhahlobo, bahlahisi ba ka tseba le ho lokisa mefokolo leha e le efe kapa ho se lumellane ho li-welds tsa mabala, ho netefatsa hore ho latela litekanyetso le litlhaloso tsa indasteri. Ka mehato e matla ea taolo ea boleng, li-welds tse tšepahalang le tsa boleng bo holimo li ka finyelloa, tse tlatsetsang botšepehing le bophelo bo bolelele ba meaho e cheselitsoeng lits'ebetsong tse fapaneng.
