Imishini yokushisela izinqe zethusi ingamathuluzi abalulekile ezinqubweni ezihlukahlukene zezimboni, ezaziwa ngamandla azo okudala ama-welds aqinile futhi ahlala isikhathi eside ezingxenyeni zethusi.Kodwa-ke, ukufeza ikhwalithi yokushisela oyifunayo kuncike ezintweni ezimbalwa ezibucayi, lapho umshini wokushisela ungenye yezinto ezibaluleke kakhulu.Kulesi sihloko, sizohlola umthelela we-welding enganele emishini yokushisela ye-copper rod butt.
1. Amandla Weld Weak
I-welding current enganele ingaholela ekushiseleni okubuthakathaka futhi okungasebenzi.Inqubo yokushisela incike ekukhiqizeni ukushisa nokucindezela okwanele ukuze udale isibopho se-metallurgical phakathi kwezinduku zethusi.Uma i-current iphansi kakhulu, ukushisa okukhiqizwa kungase kunganele ukuncibilika kahle futhi kuhlanganiswe indawo engaphezulu, okuholela ekuhlanganyeleni okubuthakathaka okunamandla ancishisiwe.
2. Ukuntuleka kwe-Fusion
Ukuhlanganiswa okufanele phakathi kwezingxenye zenduku yethusi kubalulekile ekushiseleleni ubuqotho.I-welding current enganele ingase inganikezi ukushisa okudingekayo ukuze kutholakale ukuhlanganisa okugcwele.Lokhu kuntuleka kokuhlanganisa kungabonakala njengokungena okungaphelele kokusebenza kwethusi, okushiya izindawo ezingahlanganisiwe ezifaka engcupheni ubuqotho besakhiwo se-weld.
3. I-Porosity
I-welding current enganele nayo ingaholela ekwakhekeni kwe-porosity ngaphakathi kwe-weld.I-Porosity iqukethe amaphakethe egesi amancane noma ama-voids ngaphakathi kwensimbi yokushisela.Lezi voids zenza buthaka i-weld futhi zinciphise ikhwalithi yayo.Ukushisa okunganele kungabangela amagesi avalelwe, njenge-hydrogen, ukuba ahlale ensimbi encibilikisiwe kunokuba abaleke, okuholela ekwakhekeni kwe-porosity.
4. Imifantu namaphutha
I-welding current ephansi inyusa ubungozi bokulimala kwe-weld, kufaka phakathi imifantu.Imifantu ingakhula ngenxa yokufakwa kokushisa okunganele, okuholela kumaphuzu okugxilisa ingcindezi ngaphakathi kokushisela.Le mifantu ingasakazeka ngokuhamba kwesikhathi, ifake engozini ubuqotho besakhiwo se-weld futhi ibangele ukwehluleka okuyinhlekelele.
5. Ikhwalithi yokushisela engahambisani
Ikhwalithi ye-weld engahambisani ingomunye umphumela wokunganele okwamanje.Ukwehluka kwamanje kungaholela emazingeni ahlukahlukene okokufaka nokungena kokushisa, okuholela kumashisela anamandla angahambisani nokwethembeka.Lokhu kungahambisani kuyinkinga ikakhulukazi ezinhlelweni zokusebenza lapho ikhwalithi yokushisela ibalulekile.
6. Ukwenyuka Kwemisebenzi Kabusha kanye Nezicucu
Ukuba khona kwama-welds abuthakathaka, ukuntuleka kwe-fusion, i-porosity, kanye nokukhubazeka ngenxa yamanje ye-welding ephansi kungaholela ekwandeni kokusebenza kabusha kanye ne-scrap.Abakhiqizi bangase badinge ukutshala isikhathi esengeziwe kanye nezinsiza ukuze balungise noma benze kabusha amashisela asezingeni eliphansi, okuholela ekwenyukeni kwezindleko zokukhiqiza kanye nesikhathi sokuphumula.
7. Ukunciphisa Ukusebenza Ngekhono
Isidingo sokusebenza kabusha kaningi nokuhlolwa kokulawulwa kwekhwalithi, kanye nethuba lokwehluleka kwengxenye, kunganciphisa kakhulu ukusebenza kahle kwemishini yokushisela izinqe zethusi.Amashejuli okukhiqiza angase aphazamiseke, futhi izinsiza zingase ziphambukiswe ukuze kubhekwane nezinkinga zokushisela.
Sengiphetha, ukushisela okunganele emishinini yokushisela induku yethusi kungaba nomthelela omubi kwikhwalithi yokushisela kanye nokusebenza kahle okuphelele.Ukuqinisekisa ukushiselwa okuqinile, okuthembekile, kanye nekhwalithi ephezulu ezingxenyeni zethusi, kubalulekile ukusetha nokugcina imingcele yamanje yokushisela efanele ngokuya ngezidingo ezithile zohlelo lokusebenza.Ukuqeqeshwa okufanele kanye nokugcinwa kwemishini evamile nakho kubalulekile ukuze kuzuzwe imiphumela engaguquki nethembekile yokushisela.
