Xana ndzi fanele ku endla yini loko ndzi hlangana na swihoxo swa non-fusion na non-penetration endzhaku ka valve welding?

1. Swihlawulekisi swa swihoxo
Unfused swivula xiendlakalo xa leswaku nsimbi ya weld ayi n’oki hiku hetiseka naswona yihlanganisiwa na nsimbi yale hansi kumbe exikarhi ka ti layers ta nsimbi ya weld.
Ku tsandzeka ku nghena swivula xiendlakalo xa leswaku rimitsu ra nhlangano lowu weldiweke ari ngheni hiku hetiseka.
Havumbirhi bya non-fusion na non-penetration swita hunguta ndzhawu leyi tirhaka ya cross-sectional ya weld, leswi hungutaka matimba xikan’we naku tiya.
2. Swivangelo
Xivangelo xa non-fusion: welding current yitsongo swinene kumbe welding speed yi hatlisa swinene, leswi endlaka leswaku kuva na kuhisa loku ringaneleke, naswona base metal na filler metal ayi koti ku n’okisiwa hiku hetiseka. Angle ya groove yitsongo swinene, gap yitsongo swinene kumbe blunt edge yikulu swinene, leswaku arc yinga ngheni swinene eka rimitsu ra groove hinkarhi wa welding, leswi endlaka leswaku base metal na weld metal swinga fused. Kuna thyaka rofana na oil stain na rust ehenhla ka weldment, leswi khumbhaka ku n’oka naku hlanganisiwa ka nsimbi. Ku tirha lokunga fanelangiki, kufana na electrode angle leyinga lulamangiki, ndlela leyinga fanelangiki yo fambisa bar, na swin’wana, swiendla leswaku arc yi hambuka kusuka eka tlhelo ra groove kutani yi tsandzeka ku funengeta groove hindlela leyi ringaneleke.
Swivangelo swa ku nga ngheni: Swifana na swivangelo swin’wana swa non-fusion, kufana na welding current leyintsongo swinene, rivilo ra welding hiku hatlisa swinene, groove size leyinga fanelangiki, etc. Loko ku welda, arc yi lehe ngopfu, naswona kuhisa ka arc ku hangalaka, leswi endlaka leswaku kuva na ku n’oka lokunga kahle ka nsimbi ya timintsu. Xivandla xa nhlengeletano ya weldment ayi ringani, naswona swa olova kuva kungari na ku nghena ka weld eka xiphemu lexingana xivandla lexikulu.
3. Ku lulamisiwa ka swilo
Vutshunguri lebyi nga hlanganisiwangiki: Eka swilo leswi nga hlanganisiwangiki, vhilwa ro sila ri nga tirhisiwa ku pholisha swiphemu leswi nga hlanganisiwangiki ivi ku tlhela ku welda. Loko ku tlhela ku welda, ti parameters ta maendlelo ya welding tifanele ku lulamisiwa kutiyisisa leswaku ku nghenisiwa ka kuhisa loku ringaneleke kuva ku n’okisiwa hiku hetiseka nsimbi ya base na nsimbi ya filler. Eka non-fusion yale ndzeni, hi xitalo swa laveka kutirhisa tindlela to kambela letinga onhiki ku kumisisa ndzhawu na vukulu bya non-fusion, kutani kutirhisiwa tindlela ta carbon arc gouging kumbe machining ku susa swiphemu leswinga fusion, kutani ku endliwa repair welding. Loko u lunghisa welding, nyikela nyingiso eka ku basisa groove, lawula angle ya welding na ndlela yo fambisa bar.
Vutshunguri lebyi nga nghenekiki: Loko ku enta ka ku nghena loku nga weldiwangiki ku nga ri ehansi, xiphemu lexi nga nghenangiki xi nga susiwa hi ku sila hi vhilwa ro sila, ivi ku lunghisa ku welda. Eka vuenti lebyikulu, hi ntolovelo swa laveka ku tirhisa carbon arc gouging kumbe machining ku susa swiphemu hinkwaswo swa ku nghena ka weld kufikela loko nsimbi ya kahle yi paluxiwa, kutani ku lunghisa welding. Loko ku lunghisa welding, welding current, voltage na rivilo ra welding swifanele ku lawuriwa swinene kutiyisisa leswaku rimitsu ringa nghena hiku hetiseka.
4. Lulamisa swilo swo welda
Hi ntolovelo, switirhisiwa swo welda leswi fanaka kumbe leswi fanaka na switirhisiwa swa le hansi swa valve swifanele ku hlawuriwa. Xikombiso, eka ti valve ta nsimbi ya khaboni leti tolovelekeke, ti E4303 (J422) welding rods tinga hlawuriwa; Eka ti valve ta nsimbi yoka yinga tshwukangi, ti welding rods leti fambelanaka ta stainless steel tinga hlawuriwa kuya hi switirhisiwa swokarhi, kufana na ti A102 welding rods ta 304 stainless steelti- valve, A022 tinhonga to welda ta 316L ya nsimbi leyi nga riki na swilo swo bolati- valve, sw.sw.
