Lungisa ama-weld ezintweni ezingaziwa? Nanka amanye amathiphu angakusiza ukuthi ubone ukuthi yini oyibophayo. I-Getty Images
U: Umsebenzi wami uhilela ukushisela nokulungisa imishini nezakhiwo endaweni. Cishe angikaze ngitshelwe ukuthi hlobo luni lwensimbi engilufaka nge-solder. Unganginika isiqondiso sendlela engingathola ngayo uhlobo kanye nezinga lensimbi engiyisebenzisayo?
A: Iseluleko esingcono kakhulu engingasinikeza ukuthi ungazami ukusihlanganisa uma ungazi ukuthi siyini. Lokhu kuyiqiniso ikakhulukazi ezingxenyeni ezibalulekile lapho ukwehluleka kungaholela ekulimaleni noma ekufeni.
Ukushisela ezinsimbini ezithile kusetshenziswa izinqubo zokushisela ezingafanele kungabangela amaphutha ensimbi eyisisekelo, ekushiseleni, noma kokubili.
Uma ucelwa ukuthi ushisele into engaziwa, unquma kanjani ukuthi iyini? Okokuqala, kufanele ukwazi ukusebenzisa ukuhlolwa okuyisisekelo ukuze unciphise amathuba. Bheka ubuso bento bese ubona ukuthi inzima kangakanani. Lokhu kufanele kukuvumele ukuthi uhlukanise izinto zibe yizigaba ezibanzi njengezinto zensimbi ezine-carbon noma ezi-low alloy, izinsimbi zensimbi engagqwali noma i-nickel noma izinsimbi ze-aluminium. Ukuhlola indawo lapho udinga ukushisela khona kungakunikeza nezinkomba ezibalulekile. Ingabe kukhona ubufakazi bokuthi ingxenye yayishisele ngesikhathi senqubo yokuqala yokukhiqiza? Uma kunjalo, lokhu kuyisibonakaliso esihle sokushiseleka kwezinto. Ingabe kukhona ubufakazi bokuthi ukulungiswa kwe-weld kuye kwazanywa? Uma ukulungiswa kwe-solder kwangaphambilini kuhlulekile, lokho kuyisibonakaliso esibomvu esikutshela ukuthi uqiniseke ukuthi usebenzisa ini ngaphambi kokuzama ukulungisa okusha.
Uma ulungisa umshini, ungashayela umenzi wokuqala ukubuza ukuthi iyiphi impahla esetshenzisiwe. Ezinye izinto zivame ukwenziwa ngezinto ezithile. Isibonelo, izibambo ze-aluminium zivame ukwenziwa kusetshenziswa ibanga 6061. Ukwenza ucwaningo ngezinto ezivame ukusetshenziselwa ukwenza izinto ezizoshintshwa kungakusiza ukuthi unciphise izinketho zakho.
Njengoba usebenza esitolo semishini, kufanele ukwazi ukuthola ulwazi oluhle kakhulu ngezinto zokwakha kumekhenikha. Uma bekhanda into entsha, uchwepheshe wemishini angase azi kahle ukuthi iyini. Bangakunikeza ulwazi oluhle mayelana nezinto zokwakha ngokusekelwe ezicini zayo zokucubungula. Kufanele ukwazi ukulinganisa ubulukhuni bensimbi ngokusekelwe emazingeni okuphakelayo kanye nesivinini esisetshenziswa ngesikhathi sokulungisa. Indlela ama-chip okulungisa akhiwa ngayo inikeza nolwazi oluwusizo. Kufanele ugweme ukushisela izinsimbi ezikhiqiza ama-chip amancane, njengoba lawa kungenzeka abe yizinga lokusika elikhululekile elivame ukuqhekeka lapho lishisiwe.
Ukuhlolwa kwenhlansi yensimbi nensimbi ephonswe kungakunikeza umbono oqondile wokuthi ingakanani ikhabhoni equkethwe yile nto. Ukuhlolwa kwamachaphaza amakhemikhali nakho kunganquma ukuba khona kwezinto ezithile zokuhlanganisa.
Ukuhlaziywa kwamakhemikhali kuzohlinzeka ngolwazi olungcono kakhulu ukusiza ekuboneni amazinga ezinto. Ezimweni eziningi, ungathumela ama-chip omshini avela ezintweni ukuze ahlaziywe. Uma kungekho mfucumfucu womshini, uma kungenzeka, susa ingxenye encane yezinto ukuze ihlaziywe - cishe i-intshi eli-1. Isikwele. Amalabhorethri amaningi okuhlola anikeza ukuhlaziywa kwamakhemikhali ensimbi ngaphansi kwama-$200 ezimweni eziningi.
Okubaluleke kakhulu, uma ufuna ukwenza ukulungiswa okuphephile nokuhlala isikhathi eside, kubalulekile ukuchitha isikhathi nemali encane ukuze uthole umbono omuhle wokuthi yiziphi izinto ozozishisela.
I-WELDER, eyayibizwa ngokuthi i-Practical Welding Today, ibonisa abantu bangempela abenza imikhiqizo esiyisebenzisayo nesisebenza ngayo nsuku zonke. Lo magazini ukhonze umphakathi wokushisela eNyakatho Melika iminyaka engaphezu kwengu-20.
