Zvivakwa uye Zvishandiso zveArgon-Hydrogen Mixtures muWelding
Argon-hydrogen musanganiswavakawana kutariswa kwakakosha mumunda wewelding nekuda kwezvivakwa zvavo zvakasiyana uye huwandu hwakawanda hwekushandisa. Ichi chinyorwa chine chinangwa chekuongorora zvakasiyana-siyana zve argon-hydrogen musanganiswa uye kukurukura mashandisiro azvo mukuita welding. Nekunzwisisa izvi zvivakwa uye mashandisirwo, ma welders anogona kukwirisa maitiro avo ekugadzira uye kuwana emhando yepamusoro welds.
1. Zvinhu zveArgon-Hydrogen Mixtures:
1.1 Kuwedzera Kupinza Kupisa: Argon-hydrogen misanganiswa ine yakakwirira yekupisa conductivity ichienzaniswa neiyo argon yakachena. Izvi zvinoguma nekuwedzera kupisa kwekuisa panguva yewelding process, zvichitungamira kune nani kupinda mukati uye nekukurumidza welding kumhanya.
1.2 Enhanced Arc Stability: Kuwedzerwa kwehydrogen kune argon kunonatsiridza arc kugadzikana nekudzikisa kudonha kwemagetsi kuyambuka arc. Izvi zvinobvumira kudzora kurinani kweiyo welding process, kuderedza spatter uye kuve nekuona yakagadzikana arc mukati meweld.
1.3 Yakanatsiridzwa Yekudzivirira Gasi: Argon-hydrogen musanganiswa inopa yakanakisa kudzivirira zvivakwa, kudzivirira kusvibiswa kwemhepo kwechidziva cheweld. Iyo yehaidhirojeni yemusanganiswa inoita segasi rinoshanda, rinonyatsobvisa maokisi uye zvimwe zvitsvina kubva munzvimbo yeweld.
1.4 Yakaderedzwa Heat Affected Zone (HAZ): Kushandiswa kweargon-hydrogen misanganiswa inoguma mune yakamanikana uye isinganyanyi kukanganiswa HAZ kana ichienzaniswa nemamwe magasi ekudzivirira. Izvi zvinonyanya kubatsira kune welding zvinhu zvine yakakwira thermal conductivity, sezvo ichideredza kukanganisa uye inovandudza huwandu hweweld.
2. Mashandisirwo eArgon-Hydrogen Mixtures muWelding:
2.1 Carbon Steel Welding: Argon-hydrogen misanganiswa inowanzoshandiswa kugadzira kabhoni simbi welding nekuda kwekugona kwavo kupa yakadzika kupinda uye yakakwirira welding kumhanya. Iyo yakakwidziridzwa arc kugadzikana uye yakagadziridzwa ekudzivirira zvivakwa inoita kuti misanganiswa iyi ive yakanakira kuwana yakasimba uye yakasimba welds mune kabhoni simbi yekushandisa.
2.2 Stainless Simbi Welding: Argon-hydrogen musanganiswa akakodzerawo simbi isina tsvina. Iyo yehaidhirojeni yemusanganiswa inobatsira kubvisa maokisi epamusoro, zvichikonzera kuchenesa welds nekuderedzwa porosity. Pamusoro pezvo, iyo yakawedzera kupisa yekuisa inobvumira kukurumidza kumhanyisa kumhanya, kuvandudza chibereko mukugadzirwa kwesimbi isina tsvina.
2.3 Aluminium Welding: Kunyange zvazvo argon-helium musanganiswa achiwanzo shandiswa kugadzira aruminiyamu welding, argon-hydrogen misanganiswa inogonawo kushandiswa. Iyi misanganiswa inopa zvirinani arc kugadzikana uye yakagadziridzwa yekuchenesa chiito, zvichikonzera emhando yepamusoro welds ane hurema hwakadzikira.
2.4 Copper Welding: Argon-hydrogen misanganiswa inogona kushandiswa kugadzira mhangura, ichipa yakanakisa arc kugadzikana uye kunatsiridza kupisa kupinza. Iyo hydrogen yemukati musanganiswa inobatsira kubvisa copper oxides, kuve nechokwadi chekuchenesa uye yakasimba welds.
Argon-hydrogen musanganiswa ine yakasarudzika zvivakwa zvinoita kuti ive yakanyanya kukodzera kune akasiyana welding application. Kuwedzera kwavo kupisa kupinza, kusimba kwe arc, kunatsiridza zvivakwa zvekudzivirira, uye kuderedzwa HAZ zvinovaita sarudzo yakanaka yekabhoni simbi, Stainless simbi, aluminium, uye copper welding. Nekushandisa argon-hydrogen musanganiswa, welders anogona kuwana emhando yepamusoro welds ane kugadzirwa kwakavandudzwa uye kuderera kwakaderedzwa. Izvo zvakakosha kuti velders vanzwisise zvivakwa uye mashandisirwo eargon-hydrogen musanganiswa kuti vagone kukwirisa maitiro avo ekuwelda uye kuve nechokwadi chakabudirira mhedzisiro mumapurojekiti avo emagetsi.
