I-Aluminium nokuningi: Ukulawula ukushisa kuyisihluthulelo se-aluminium yokushisela

I-Aluminium idinga ukushisa okuningi—okucishe kuphindwe kabili kunensimbi—ukuyishisisa ngokwanele ukuze yenze amachibi.Ukwazi ukulawula ukushisa kuyisihluthulelo sempumelelo yokushisela i-aluminium.Getty Images
Uma usebenza kuphrojekthi ye-aluminium futhi indawo yakho yokunethezeka iyinsimbi, uzobona ngokushesha ukuthi konke okwaziyo mayelana nensimbi yokushisela ngempumelelo ngeke kusebenze uma kufakwe ku-aluminium.Lokhu kungase kukhungathekise kakhulu uze uqonde umehluko obalulekile phakathi kwezinto ezimbili.
I-Aluminium idinga ukushisa okuningi—okucishe kuphindwe kabili kunensimbi—ukuyishisisa ngokwanele ukuze yenze ama-puddles.Inomoya oshisayo ophakeme kakhulu.Yize i-aluminium ikwazi ukumunca ukushisa okuningi futhi ihlale iqinile, lokho akusho ukuthi kufanele ukhuphule ugesi futhi uthembele ngemiphumela engcono kakhulu lapho u-soldering.Kudingeka ulandele isethi yemingcele ukuze ufinyelele umphumela oyifunayo.
Indlela elula yokudayela emshinini iwukuba wenyuse noma wehlise i-voltage ngesilinganiso esingu-5 uze uthole idamu elimanzi elicwebezelayo phakathi nemizuzwana emithathu.Uma uthola amanzi ngomzuzwana noma emibili, wehlise i-voltage ngo-5 kuze kwenzeke phakathi nemizuzwana emithathu.Awekho ama-puddles ngemizuzwana emithathu?Khulisa i-voltage ngo-5 uze wenze kanjalo.
Ekuqaleni kokushisela kwe-TIG, udinga ukucindezela ngokuphelele ama-pedals ukuze ukhiqize ukushisa okwanele, kodwa uma uqala ukuhlanganisa, udinga ukususa ama-pedals ubuyele emuva.Ukubuka iphrofayili yakho yobuhlalu kuzokunikeza inkomba ebonakalayo yokuthi udinga ingcindezi engakanani.
Lapho ngifundisa abanye, ngachaza ukuthi badinga ukumiswa kwamandla kagesi aphansi kakhulu ukuze banikeze izinga lokushisa elingcono kakhulu lokusebenza.Ukushisa okudlulele kungabangela ukuqhekeka kwe-weld, ukufakwa kwe-oxide, ukuthambisa indawo ethintekile ukushisa, kanye ne-porosity-konke okungahle kunciphise impahla yakho futhi kuthinte izinga le-weld yakho, kokubili kwesakhiwo nokubukeka.
Ngokulawula okugcwele kokufaka kokushisa, ungakwazi ukulawula futhi ngethemba ukuqeda lezi zinkinga ezivamile.
I-WELDER, eyayaziwa ngokuthi i-Practical Welding Today, ibonisa abantu bangempela abenza imikhiqizo esiyisebenzisayo nesisebenza ngayo nsuku zonke.Lo magazini ususebenzele umphakathi wokushisela eNyakatho Melika iminyaka engaphezu kwengu-20.
