nga kampuni ya payoniya mu . Stainless Steel Industrial Welded Pipe Production Equipment Industry, Hangao Tech . eggyamu ebifundikwa okuva mu bumanyirivu bw’abakozesa. Leero, twogera okuva mu ndowooza ey’ekikugu nti nga tukyusa obutonde bw’omukka oguziyiza, ebikulu ebitaano ebivaamu ku nkola y’okuweta bijja kukolebwa:
(1) Okulongoosa omutindo gw’okuteeka waya ya welding bw’ogeraageranya ne kaboni dayokisayidi omulongoofu ow’ennono, omukka ogutabuddwa ogulimu argon gutera okuleeta obulungi bw’okufulumya. Ebirimu argon birina okusukka 85% okutuuka ku nkyukakyuka ya jet. Kya lwatu, okulongoosa omutindo gw’okuteeka waya ya welding kyetaagisa okulonda ebipimo ebituufu eby’okuweta. Ekikolwa kya welding kitera okuba ekiva mu bipimo ebingi. Okulonda parameter ya welding inappropriate kujja kutera okukendeeza ku welding efficiency n’okwongera ku slag removal work oluvannyuma welding.
(2) Okufuga spatter n’okukendeeza ku potential ya ionization entono eya argon oluvannyuma lw’okuweta slag cleaning erongoosa arc stability era correspondingly ekendeeza ku spatter. Tekinologiya w’amaanyi amapya ow’okuweta (welding power technology) omupya afuga okufuumuuka kwa kaboni dayokisayidi welding. Mu mbeera y’emu, singa omukka ogutabuddwa gukozesebwa, gusobola okwongera okukendeeza ku kufuuwa n’okugaziya eddirisa lya welding parameter.
(3) Okufuga okuweza okuweweeza okuweweeza, okukendeeza ku welding ya kaboni dayokisayidi omusono gwa welding gutera okufuluma ebweru, ekivaako okuweta okuyitiridde n’okwongera ku ssente za welding. Omukka ogutabuddwa mu argon kyangu okufuga okutondebwa kw’omusono gwa welding n’okwewala okusaasaanya waya ya welding.
(4) Okulongoosa sipiidi y’okuweta. Nga okozesa omutabula gwa ggaasi ogulimu argon, ne bwe kiba nti akasannyalazo aka welding kayongerwako, ekifuumuuka kikyayinza okufugibwa obulungi ennyo. Enkizo ereetebwa kino kwe kwongera ku sipiidi ya welding naddala ku otomatiki welding, ekiyamba ennyo okufulumya obulungi.
(5) Okufuga okuweta omukka. Wansi w’ebipimo bye bimu eby’okukola welding, omutabula omungi mu argon gukendeeza nnyo omukka gwa welding bw’ogeraageranya ne kaboni dayokisayidi. Okugerageranya n’okussa ssente mu byuma ebikozesebwa okulongoosa embeera y’emirimu gy’okuweta, okukozesa omutabula gwa ggaasi omungi mu argon, nsonga ya butanwa okukendeeza ku bucaafu bw’ensibuko.
Okutwaliza awamu, kiyinza okulabibwa nti nga olondawo omukka ogusaanira ogw’okuweta, omutindo gw’okuweta gusobola okulongoosebwa, okuweta omuwendo gwonna guyinza okukendeezebwa, era obulungi bw’okuweta busobola okulongoosebwa.
Mu kiseera kino, mu makolero mangi, argon gas mixtures zibadde zikozesebwa nnyo, naye olw’ensonga ez’enjawulo, ebitongole ebisinga obungi eby’omunda mu ggwanga bikozesa 80% argon AR+20% carbon dioxide. Mu nkola nnyingi, omukka oguziyiza tegukola bulungi. N’olwekyo, okulonda ggaasi asinga mu butuufu y’engeri ennyangu ey’okulongoosaamu omutindo gw’okuddukanya ebintu eri ekitongole ekiweta mu kkubo erigenda mu maaso. Omusingi ogusinga obukulu ogw’okulonda omukka ogusinga obulungi ogw’okuziyiza kwe kutuukiriza ebisaanyizo byennyini eby’okuweta ku kigero ekisinga. Okugatta ku ekyo, omuwendo omutuufu ogw’okukulukuta kwa ggaasi kye kyetaagisa okukakasa omutindo gw’okuweta, era omuwendo gw’amazzi ogukulukuta ennyo oba omutono ennyo teguyamba ku welding.
