Izindlela Zokuhlola Zokuhlanganiswa Kwe-Weld Emishinini Yokushisela Isitoreji Samandla Spot

Emishinini yokushisela indawo yokugcina amandla, ukuqinisekisa ikhwalithi nobuqotho bamalunga okushisela kubaluleke kakhulu. Ukuze kuzuzwe lokhu, kusetshenziswa izindlela ezihlukahlukene zokuhlola ukuze kuhlolwe amajoyinti okushisela ukuze kutholakale iziphambeko, njengokuhlangana okunganele, ukuqhekeka, noma ukubola. Lesi sihloko sihlola amasu ahlukene okuhlola amalunga e-weld emishinini yokushisela indawo yokugcina amandla, ihlinzeka opharetha ngamathuluzi abalulekile okugcina ama-welds ekhwalithi ephezulu.

1. Ukuhlola Okubonwayo: Ukuhlola okubonwayo kuyindlela eyisisekelo nevame ukusetshenziswa yokuhlola amalunga okushisela. Ama-opharetha ahlola ngokubukeka indawo yokushisela ukuze abone noma yikuphi ukukhubazeka okubonakalayo, njengokuhlanganisa okungaphelele, ukungahambi kahle kwendawo, noma ukungaqhubeki. Le ndlela idinga iso eliqeqeshiwe kanye nezimo zokukhanyisa ezanele ukuze zihlonze ngokunembile izinkinga ezingase zibe khona.
2. Amasu Okuhlola Okungabhubhi (NDT): a. Ukuhlolwa kwe-Ultrasonic: Ukuhlola kwe-Ultrasonic kusebenzisa amaza omsindo wemvamisa ephezulu ukuze kutholwe amaphutha angaphakathi noma amaphutha kumajoyini wokushisela. Amaza e-Ultrasonic asakazwa ngejoyinti le-weld, futhi amagagasi abonisiwe ayahlaziywa ukuze kutholakale noma yikuphi ukungahambi kahle. Le nqubo iphumelela kakhulu ekutholeni imifantu engaphansi komhlaba noma i-porosity.

b. Ukuhlolwa kwe-Radiographic: Ukuhlolwa kwe-radiographic kuhilela ukudlulisa ama-X-reyi noma imisebe ye-gamma ngejoyinti le-weld kanye nokuthwebula isithombe ngefilimu noma umtshina wedijithali. Le ndlela ingadalula amaphutha angaphakathi, njengokungena okungaphelele noma izikhala. Ukuhlolwa kwe-radiographic kuwusizo ikakhulukazi kumajoyinti e-weld aqinile noma ayinkimbinkimbi.

c. Ukuhlolwa Kwezinhlayiyana Zazibuthe: Ukuhlolwa kwezinhlayiyana zikaMagnetic kusetshenziselwa ukuhlola izinto ze-ferromagnetic. Insimu kazibuthe isetshenziswa ekuhlanganyeleni kwe-weld, futhi izinhlayiya kazibuthe zisetshenziswa phezulu. Noma yikuphi ukukhubazeka okuphuka phezulu kuzobangela ukuthi izinhlayiya kazibuthe zihlangane, okubonisa ukuba khona kwesici.

d. Ukuhlolwa kwe-Dye Penetrant: Ukuhlolwa kokungena kwedayi kusetshenziselwa ukuthola amaphutha angaphezulu kumajoyinti e-weld. Udayi onemibala usetshenziswa ebusweni, futhi ngemva kwesikhathi esithile, udayi owedlulele uyasuswa. Unjiniyela ube esesetshenziswa, odonsa udayi oboshiwe kunoma yikuphi ukonakala kwendawo, awenze abonakale.

3. Ukuhlola Okulimazayo: Ezimweni ezithile, ukuhlolwa okulimazayo kuyadingeka ukuze kuhlolwe ikhwalithi yejoyinti le-weld. Lokhu kuhilela ukukhipha ingxenye yesampula yejoyinti lokushisela nokulifaka ezivivinyweni ezihlukahlukene, njengokuhlola ukuqina, ukugoba, noma ukuhlolwa kokuqina. Ukuhlola okulimazayo kunikeza ulwazi oluningiliziwe mayelana nezakhiwo zemishini yejoyinti le-weld futhi kungadalula amaphutha afihliwe.

Ukuhlola amajoyinti e-weld emishinini yokushisela indawo yokugcina amandla kubalulekile ukuze kuqinisekiswe ikhwalithi yokushisela kanye nobuqotho besakhiwo. Ngokusebenzisa ukuhlola okubukwayo, amasu okuhlola angalimazi (njengokuhlolwa kwe-ultrasonic, ukuhlolwa kwe-radiographic, ukuhlolwa kwezinhlayiyana kazibuthe, nokuhlola ukungena kwedayi), futhi, lapho kudingekile, ukuhlola okulimazayo, opharetha bangahlola ngempumelelo amalunga e-weld ukuze abone amaphutha. Ukusebenzisa uhlelo lokuhlola olubanzi kusiza ukugcina amazinga aphezulu ekhwalithi nokuthembeka ezinhlelweni zokushisela indawo yokugcina amandla. Ukuhlola okuvamile kunika amandla ukuhlonzwa ngokushesha nokuxazululwa kwanoma yiziphi izinkinga, okuholela ekuthuthukisweni kwekhwalithi ye-weld nokusebenza kukonke kwe-welding.
