Wazi kangakanani ngezinto zokushisela? Ungaphuthelwa inani eliphelele! (II)

4. Ingxube ye-Aluminium

Njengoba sonke sazi, ukuqhutshwa kokushisa kwe-aluminium alloys kuphezulu kakhulu. Ngaphandle kwalokho, ama-alloys e-aluminium nawo ane-reflection ephezulu. Ngakho-ke, uma i-laser welding idingeka kuma-alloys e-aluminium, ukuminyana kwamandla aphezulu kuyadingeka. Isibonelo, uchungechunge olujwayelekile 1 kuya ku-5 lungashiselwa nge-laser. Yiqiniso, kukhona nezinye izingxenye eziguquguqukayo ku-alloy ye-aluminium, njengeshidi lika-galvanized ngaphambili, ngakho-ke akunakugwenywa ukuthi enye i-steam izongena ekushiseleni ngesikhathi senqubo yokushisela, ngaleyo ndlela yakha izimbobo ezithile zomoya. Ngaphezu kwalokho, i-viscosity ye-aluminium alloy iphansi, ngakho-ke singakwazi ukuthuthukisa lesi simo ngokuklama okuhlangene ngesikhathi sokushisela.

5. Ingxubevange ye-Titanium/titanium

I-Titanium alloy nayo iyinto evamile yokushisela. Ukusebenzisa i-laser welding ukushisela i-titanium alloy akukwazi nje ukuthola amajoyinti wokushisela wekhwalithi ephezulu, kodwa futhi nokuba nepulasitiki engcono. Njengoba impahla ye-titanium ilula futhi imnyama kugebe elikhiqizwa igesi, kufanele sinake kakhulu ukwelashwa okuhlangene nokuvikelwa kwegesi. Ngesikhathi sokushisela, ukunakwa kufanele kukhokhwe ekulawuleni i-hydrogen, engadambisa ngokuphumelelayo ukulibaziseka kokuqhekeka kwe-titanium alloy kunqubo yokushisela. I-porosity iyinkinga evamile yezinto ze-titanium kanye nama-titanium alloys ngesikhathi sokushisela. Nazi ezinye izindlela eziphumelelayo zokuqeda i-porosity: okokuqala, i-argon enobumsulwa obungaphezu kuka-99.9% ingakhethwa ukushisela. Okwesibili, ingahlanzwa ngaphambi kwe-welding. Okokugcina, imininingwane yokushisela ye-titanium ne-titanium alloys kufanele ilandelwe ngokuqinile enqubweni yokushisela. Ngale ndlela, isizukulwane sama-pores singagwenywa ngezinga elikhulu kakhulu.

6. Ithusi

Abantu abaningi bangase bangazi ukuthi ithusi liyinto evamile ekushiseleni. Izinto zethusi ngokuvamile zihlanganisa ithusi nethusi elibomvu, okungokwezinto eziphakeme zokulwa nokukhanya. Uma ukhetha ithusi njengento yokushisela, qaphela okuqukethwe kwe-zinc kuyo. Uma okuqukethwe kuphezulu kakhulu, inkinga yokushisela yeshidi lama-galvanized okukhulunywe ngenhla izokwenzeka. Endabeni yethusi ebomvu, ukunakwa kufanele kukhokhwe ku-energy density ngesikhathi sokushisela. Ukuminyana kwamandla okuphezulu kuphela kunganelisa umsebenzi wokushisela wethusi obomvu.
Lokhu ukuphela kokusungula kwezinto ezivamile zokushisela. Sethule izinto ezijwayelekile ezahlukahlukene ngokuningiliziwe, ngethemba lokukusiza
