Zvechinyakarepombi yemafutawelding, iyo mhando yakaoma kudzora uye yakaoma kuwana inodiwa welding slag haibvumidzwe mukati, zvisinei, inoshanda uye yakawanda inoshandiswa welding backing inogadzirwa, manual arc welding nzira yekuvhara.Nenzira iyi yakajeka arc, welding oparesheni iri nyore, isinganyanyi kutarisika pores, slag, isina kukwana kupinda uye zvimwe zvinokanganisa weld mushure, panguva iyi, nekuda kwediki mutsara kugona, saka diki kupisa-kukanganisa nzvimbo, kudiki deformation uye kutsemuka maitiro.

Tungsten inert gasi welding pfupiso TIG (Tungsten Inert Gasi Weiding) welding.Iri pasi pekuchengetedzwa kwegasi inert, kushandiswa kwe tungsten arc inogadzirwa ne electrode uye workpiece base material uye inopisa melt filler wire (filler wire kana yakashandiswa) inzira ye welding.Kuenderera mberi welding yekudzivirira gasi yakabviswa kubva pamuromo wetochi, iyo arc inoumbwa yakatenderedza yekudzivirira layer yakaparadzaniswa nemhepo gasi, kudzivirira kukuvadza kwakanyanya pane tungsten kupisa kwakakanganisika nzvimbo yakatenderedza dziva re weld, ichibvumira emhando yepamusoro welds.

TIG welding zvakanakira:

1) TIG welding inogona weld simbi uye nezvimwe, argon welding nzvimbo inogona kunyatsoparadzaniswa kubva kumhepo yakatenderedza, haina kunyungudutsa simbi, uye simbi haina kuita.TIG welding process, arc welding pamwe neautomatic scavenging surface oxide film.Naizvozvo, kubudirira dzimwe nzira welding nyore oxidized nyore welded, nitriding, kemikari reactivity uye yakasimba non-ferrous simbi, Stainless simbi uye siyana alloys.

2) kudzivirira maitiro, yakakwirira weld mhando.Ar ndeimwe yegasi yakagadzika uye inert isingaite nesimbi reaction, inonyungudika mumvura simbi haiburitse pores, saka inoshanda zvakanaka kudzivirira.Welding process iri nyore kunyungudika simbi uye crystallization process, uye nekudaro yakakwira weld mhando.

3) Nekuda kwekudzvanywa uye kutonhora kwearc nekuyerera kweargon, iyo welding kusagadzikana uye deformation idiki, iyo arc yekupisa kupisa uye yakanyanya tembiricha argon, inogona kuve nechokwadi chekuti weld midzi inopinda, madiki anokanganisa kupisa-nzvimbo majoini, diki welding deformation. uye tsika yekutsemuka .Kunyanya kune yakakura welded simbi mhepo quenching maitiro.

4) tungsten arc kugadzikana, kunyangwe mune diki welding ikozvino (<10A) ichiri pasi pemoto wakatsiga, kunyanya kune dzakatetepa, dzakatetepa plate welding zvinhu.

5) kupisa uye waya yekuzadza inogona kudzorwa, uye saka zviri nyore kugadzirisa kupisa kwekuisa kunogona kusungirirwa munzvimbo dzakasiyana siyana, asiwo nzira yakanaka yekuwana inotumbuka padivi welding.

6) Sezvo waya yekuzadza isingapfuure nepakati, haiburitse spatter, weld kutaridzika.

7) Ar igasi reatomu rimwe chete, diki kupisa simba, kuderera kwekushisa kwekushisa, kushandiswa kwekushisa, kupisa kwakadzikama kwearc kunobatsira zvikuru, kunyange mumamiriro ezvinhu akaderera uye arc yakareba, arc inoramba yakagadzikana, iri nyore kushanda, nyore dzora weld quality kune yakaoma makwara pombi welding chinzvimbo zvese-chinzvimbo welding.

TIG welding iri nyore kushanda nekuda kwemhando yakanaka, mumakore achangopfuura, yave nzira yakajairika kumakambani ekugadzira magetsi mukuisa nekuchengetedza bhailer yekudziya pamusoro pemachubhu akaiswa welded.Pasi pemamiriro ekuchengetedza nzvimbo, uye kushanda kwenzvimbo yewelding nenzvimbo yezvipingamupinyi, nzira yekugadzira inowanzoshandiswa ndeyekuisa TIG welding SMAW kuvhara chiso chose kana kushandiswa kweTIG welding.
