Ukuhlolwa Kwekhwalithi ku-Medium-Frequency Inverter Spot Welding

Ukuhlolwa kwekhwalithi kuyisici esibalulekile se-medium-frequency inverter spot welding ukuze kuqinisekiswe ubuqotho nokuthembeka kwamajoyinti okushisela. Lesi sihloko sigxile ekuxoxeni ngezindlela nezindlela ezahlukahlukene ezisetshenziselwa ukuhlolwa kwekhwalithi ezinqubweni zokushisela indawo ye-inverter ye-medium-frequency.

1. Ukuhlola Okubonwayo: Ukuhlola okubonwayo kuyindlela eyinhloko esetshenziselwa ukuhlola ikhwalithi yokushisela amabala. Ama-opharetha ahlola amajoyinti e-weld ukuze abone noma yikuphi ukukhubazeka okubonakalayo njengokuhlangana okungaphelele, ukuqhekeka, ukuqina, noma ukuma kwe-nugget okungajwayelekile. Ukuhlola okubonakalayo kusiza ukuhlonza ukungapheleli kwendawo kanye nokungahambisani okungase kuthinte ubuqotho besakhiwo sokushisela.
2. I-Dimensional Measurement: I-Dimensional measurement ihlanganisa ukuhlola ubukhulu bomzimba bamashisela ukuze kuqinisekiswe ukuthi bayahlangabezana nezidingo ezishiwo. Lokhu kufaka phakathi amapharamitha wokulinganisa afana nobubanzi be-nugget, ubude be-nugget, ububanzi be-weld, nosayizi wokuhlehlisa. Izilinganiso zobukhulu ngokuvamile zenziwa kusetshenziswa ama-caliper, ama-micrometer, noma amanye amathuluzi okulinganisa anembayo.
3. Ukuhlola Okungabhubhisi (NDT): Kusetshenziswa izindlela zokuhlola ezingabhubhisi ukuze kuhlolwe ikhwalithi yangaphakathi yokushisela amabala ngaphandle kokudala umonakalo. Izindlela ezijwayelekile ze-NDT ezisetshenziswa ekushiseleni indawo ye-inverter ye-medium-frequency zihlanganisa: a. Ukuhlolwa kwe-Ultrasonic (UT): Amagagasi e-Ultrasonic asetshenziselwa ukubona ukukhubazeka kwangaphakathi njenge-voids, i-porosity, nokuntuleka kokuhlanganiswa ngaphakathi kwamajoyini we-weld. b. Ukuhlolwa kwe-Radiographic (RT): I-X-ray noma imisebe ye-gamma isetshenziselwa ukuhlola amashisela ukuze kutholwe ukukhubazeka kwangaphakathi njengokuqhekeka, ukuhlanganisa okungaphelele, noma okufakiwe. c. I-Magnetic Particle Testing (MT): Izinhlayiya zikamagnetic zisetshenziswa endaweni yokushisela, futhi ukuba khona kokuphazamiseka kazibuthe kubonisa ukonakala okungaphezulu noma okuseduze kobuso. d. Ukuhlolwa kwe-Dye Penetrant Testing (PT): Udayi onemibala usetshenziswa endaweni eshiselayo, futhi udayi ongenela kumaphutha aphuka phezulu ukhombisa ubukhona babo.
4. Ukuhlolwa Komshini: Ukuhlolwa kwemishini kwenziwa ukuze kuhlolwe amandla kanye nezakhiwo zemishini zama-spot welds. Lokhu kufaka phakathi izivivinyo ezilimazayo ezifana nokuqina kokuqina, ukuhlola ukugunda, noma ukuhlola amakhasi, okufaka amajoyinti e-weld kumandla alawulwayo ukuze kutholwe umthamo wawo wokuthwala umthwalo kanye nobuqotho besakhiwo.
5. Ukuhlaziywa kwe-Microstructural: Ukuhlaziywa kwe-Microstructural kuhilela ukuhlola i-microstructure ye-weld zone kusetshenziswa amasu e-metallographic. Lokhu kusiza ukuhlola izici zensimbi ye-weld, njengesakhiwo sokusanhlamvu, indawo yokuhlanganisa, indawo ethinteke ukushisa, nanoma yikuphi ukudidayo kwesakhiwo esincane okungase kuthinte izici zemishini ye-weld.

Ukuhlolwa kwekhwalithi kuyisinyathelo esibalulekile sokuqinisekisa ukwethembeka nokusebenza kwama-spot welds akhiqizwa yimishini yokushisela i-medium-frequency inverter spot. Ngokusebenzisa ukuhlola okubonakalayo, ukulinganisa ubukhulu, ukuhlola okungabhubhisi, ukuhlola kwemishini, nokuhlaziywa kwe-microstructural, abakhiqizi bangahlola ubuqotho be-weld futhi bakhombe noma yikuphi ukonakala okungaba khona noma ukuchezuka kumazinga adingekayo. Izinqubo zokuhlola ikhwalithi eziphumelelayo zifaka isandla ekukhiqizweni kwama-spot welds ekhwalithi ephezulu ahlangabezana nezidingo eziqinile zezimboni ezihlukahlukene.
