Yiziphi Izinkinga Ezingenzeka Uma Okwamanje Kuphansi Kakhulu Emshinini Welding We-Flash Butt?

Emkhakheni we-welding, ukufeza ibhalansi efanele yemingcele yokushisela kubalulekile ukuze kuqinisekiswe ukuxhumana okuqinile nokuthembekile. Ipharamitha eyodwa ebalulekile ekushiseleni kwe-flash butt yi-welding current. Uma i-welding current iphansi kakhulu, ingaholela ezinhlobonhlobo zezinkinga futhi ibeke engcupheni ikhwalithi ye-weld. Kulesi sihloko, sizohlola izingqinamba ezahlukahlukene ezingavela lapho okwamanje kunganele ku-flash butt welding.

1. I-Fusion Engaphelele: I-welding current enganele ingabangela ukuhlangana okungaphelele phakathi kwezingcezu ezimbili zensimbi ezihlanganiswayo. Lokhu kusho ukuthi izinsimbi zingase zingancibiliki ngokuphelele futhi zihlangane ndawonye, ​​okuholela ekushiseleleni okubuthakathaka nokungathembeki. Ukuhlanganisa okungaphelele kuyinkinga evamile uma i-current iphansi kakhulu, njengoba ukushisa okukhiqizwa ngenele ukudala ichibi elincibilikile elifanelekile.
2. Ukungena Okungalungile: Ukungena ngendlela efanele kubalulekile ukuze kuqinisekiswe amandla nobuqotho be-weld. Lapho i-welding current inganele, i-weld ingase intule ukujula okudingekayo, okuholela ekungeneni okuncane. Lokhu kungenza ilunga libe buthaka, kwenze kube lula ukwehluleka ngaphansi kwengcindezi noma ingcindezi.
3. I-Porosity: I-low welding current ingabangela ukwakheka kwamaphakethe wegesi ngaphakathi kwe-weld, okuholela ku-porosity. Lawa maphakethe egesi angalimaza ubuqotho besakhiwo selunga futhi alenze libe lula ekugqwaleni. Ukuba khona kwe-porosity ku-weld ngokuvamile kuyinkomba yekhwalithi embi yokushisela.
4. Izakhiwo Zemishini Ezibuthakathaka: Umshini wokushisela owanele ubalulekile ukuze uthole izakhiwo ezifiselekayo zokushisela endaweni yokushisela, njengamandla aqinile kanye ne-ductility. Uma i-current iphansi kakhulu, i-weld ewumphumela ingase ibonise amandla ancishisiwe nokuqina, ikwenze ingafaneleki izinhlelo zokusebenza lapho kudingeka khona ukusebenza okuphezulu komshini.
5. Ingozi Eyandayo Yokuqhekeka: I-current enganele ingase futhi yenyuse ingozi yokuqhekeka kwi-weld kanye nendawo ezungezile ethinteke ekushiseni. Imifantu ingasakazeka nge-weld futhi ibeke engcupheni ubuqotho besakhiwo sayo yonke ingxenye. Lena inkinga enzima engaholela ekwehlulekeni komkhiqizo kanye nokukhathazeka ngokuphepha.
6. Ama-Welds Angathembekile: Ekugcineni, lapho i-welding yamanje iphansi kakhulu, ingabangela ama-welds angathembekile angase angahlangabezani namazinga embonini noma izidingo. Lawa ma-subpar welds angaholela ekusebenzeni kabusha okubizayo, ukulungiswa, noma ukuchithwa kwezingxenye ezishiselwe.

Ekuphetheni, i-welding current iyipharamitha ebalulekile ku-flash butt welding, futhi ukuntuleka kwayo kungaholela ezinhlobonhlobo zezinkinga. Ukuqinisekisa ama-welds aphezulu kanye nokuxhumana okuqinile, okuthembekile, kubalulekile ukusetha i-welding current ezingeni elifanele, kucatshangelwa izinto ezibonakalayo, ukushuba, nezinye izici ezihilelekile enqubweni yokushisela. Ukuqeqeshwa nokuqapha okwanele kubalulekile ukuze kuvinjwe izinkinga okukhulunywe ngazo ngenhla kanye nokugcina ubuqotho bezingxenye ezishiselwe.
