Izinsimbi ezicimayo zokushisela ziletha izinselele ezithile ngenxa yokuqina kwazo okuphezulu kanye nesidingo sokugcina izinto eziwumshini ozifunayo ngemva kokushisela. Kumongo we-medium frequency inverter spot welding, lesi sihloko sigxile encazelweni nemihlahlandlela yokushisela izinsimbi ezicishayo. Ukuqonda nokunamathela kulokhu kucaciswa kubalulekile ukuze kuzuzwe ukushiselwa okuthembekile nokusezingeni eliphezulu ezinhlelweni ezidinga insimbi ecishayo.
Ukukhetha Okubalulekile:
Ukukhetha insimbi ecimekayo efanele yokushisela kubalulekile. Izinsimbi ezicimekayo ezihlukene zinezinhlobonhlobo nezici zokuqina. Kubalulekile ukucabangela izici ezifana namandla afunekayo, ukuqina, kanye nezidingo zokwelashwa kokushisa kwangemva kokushisela lapho ukhetha insimbi ecishayo yohlelo oluthile.
Idizayini Ehlangene:
Idizayini ehlanganyelwe idlala indima ebalulekile ekushiseleni okuphumelelayo kwezinsimbi ezicishayo. Kubalulekile ukukhetha ukucushwa okuhlangene okuqinisekisa ukulingana okufanele, ukufinyelela okwanele kokubekwa kwama-electrode, nokusabalalisa ukushisa okulungile. Imiklamo evamile ehlangene yezinsimbi ezicishayo ihlanganisa ama-lap joints, amalunga ezinqe, nama-T-joint.
Ukulawula Ukushisa Okuphambili kanye ne-Interpass Temperature:
Ukushisa insimbi ngaphambi kokushisela kungasiza ukunciphisa ingozi yokuqhekeka nokunciphisa izingcindezi ezisele. Ukushisa kwangaphambi kokushisa kufanele kunqunywe ngokusekelwe ekubunjweni kwensimbi nokuqina. Ukwengeza, ukulawula izinga lokushisa le-interpass phakathi kwamaphasi wokushisela kubalulekile ukuvimbela ukupholisa ngokweqile nokuqinisekisa ubuqotho obufanele bokushisela.
Amapharamitha we-Welding:
Ukulungisa imingcele yokushisela kubalulekile ekushiseleni okuphumelelayo kwezinsimbi ezicishayo. Amapharamitha afana ne-welding current, isikhathi, amandla e-electrode, nesikhathi sokupholisa kufanele kulawulwe ngokucophelela ukuze kuzuzwe ukungena okufanele, ukuhlanganisa, nokulahla ukushisa. Imingcele yokushisela ingase ihluke kuye ngokuthi insimbi ethile ecishayo ishiselwa, ngakho-ke kubalulekile ukubonisana nezincomo zomkhiqizi futhi uqhube ama-welds okuhlola ukuze ukwandise imingcele.
Ukwelashwa Kokushisa Kwangemva Kwe-Weld:
Izinsimbi ezicishayo ngokuvamile zidinga ukwelashwa kokushisa kwangemuva kokushisela ukuze kuzuzwe izici ezifiselekayo zemishini. Lokhu kungase kuhlanganise izinqubo ezifana nokushisa noma ukucisha kanye nokuthulisa. Inqubo ethile yokwelapha ukushisa kufanele inqunywe ngokusekelwe ebangeni lensimbi kanye nezidingo zokuqina, amandla, nokuqina.
Ukulawula Ikhwalithi Nokuhlola:
Ukusebenzisa izinyathelo zokulawula izinga kanye nokwenza ukuhlolwa okufanele kubalulekile ukuze kuqinisekiswe ubuqotho bamashisela ezinsimbi ezicishayo. Izindlela zokuhlola ezingalimazi njengokuhlola okubonakalayo, ukuhlolwa kwe-ultrasonic, noma ukuhlolwa kwe-radiographic kufanele kusetshenziswe ukuze kutholwe noma yikuphi ukonakala okungaba khona noma ukungaqhubeki.
Ukushisela izinsimbi ezicishayo ezinomshini wokushisela amabala okushintshashintshashintshayo okuphakathi kudinga ukunamathela emibhalweni ethile nemihlahlandlela. Ngokukhetha ngokucophelela insimbi ecishayo, ukuklama okuhlangene, ukulawula ukushisa kwangaphambi kokushisa kanye nokushisa kwe-interpass, ukuthuthukisa imingcele ye-welding, ukusebenzisa ukwelashwa kokushisa kwe-post-weld, nokwenza ukulawulwa kwekhwalithi okuphelele nokuhlola, ama-welders angakwazi ukufeza ama-welds athembekile futhi aphezulu ezinhlelweni ezidinga ukucimeka. insimbi. Ukulandela le mihlahlandlela kuzoqinisekisa ukuthi izingxenye ezishiselwe zigcina izakhiwo zazo ezifiselekayo zemishini, zibe negalelo ekusebenzeni okuphelele nokuthembeka kwemikhiqizo eqediwe.
