Aya mapoinzi anotevera anofanirwa kutariswa kana uchishandisa argon arc welding:
1. Simba rekushandisa rine vertical kunze maitiro rinogamuchirwa, uye iyo yakanaka polarity inogamuchirwa muDC (waya welding inobatanidzwa nedanda risina kunaka).
2. Inowanzo kukodzera kusungirirwa kwemahwendefa matete pasi pe 6mm, ine maitiro ekugadzirwa kwakanaka kweweld uye diki deformation.
3. Iyo inodzivirira gasi ndeye argon nekuchena ≥ 99.95%.Kana iyo welding ikozvino iri 50 ~ 150A, iyo argon inoyerera iri 6 ~ 10L / min, uye kana ikozvino iri 150 ~ 250A, iyo argon inoyerera i12 ~ 15L / min.Iyo yakazara dzvinyiriro mubhodhoro haizove yakaderera pane 0.5MPa kuve nechokwadi chekuchena kweargon kuzadza.
4. Hurefu hwe tungsten electrode inobuda kubva pamuromo wegasi zviri nani 4 ~ 5mm, 2 ~ 3mm munzvimbo dzisina kudzivirirwa senge fillet welding, 5 ~ 6mm munzvimbo dzine groove yakadzika, uye chinhambwe kubva pamuromo kusvika pakushanda kazhinji hapana kupfuura 15mm.
5. Kuti udzivise kuitika kwekuputira pores, tsvina yemafuta, chiyero uye ngura pamadziro emukati uye kunze kwezvikamu zvekugadzira zvinofanira kucheneswa.
6. Iyo arc kureba kwesimbi isina simbi welding ndeye 1 ~ 3mm, uye mhedzisiro yekudzivirira haina kunaka kana yakanyanya kureba.
7. Panguva yekutsigira butt, kuitira kudzivirira kumashure kwepasi weld bead kubva kune oxidized, kumashure kunodawo kuchengetedzwa negesi.
8. Kuti uchengetedze dziva rekushongedza zvakanaka neargon uye kufambisa basa rekushongedza, kona iri pakati pemutsara wepakati we tungsten electrode uye workpiece panzvimbo yewelding ichave yakachengetedzwa pa75 ~ 85 °, uye kona inosanganisirwa pakati pekuzadza. waya uye workpiece pamusoro ichave diki sezvinobvira, kazhinji isingasviki 10 ° yemadziro ukobvu uye isingapfuuri 1mm.Kuti uone kusimba kweiyo weld, teerera kune yakanaka fusion mhando yejoini, uye zadza dziva rakanyungudutswa panguva yekumisa arc.
