Ịgbado ọkụ bụ usoro nke ihe nke workpieces ga-welded (otu ma ọ bụ dị iche iche) na-ejikọta site kpo oku ma ọ bụ nrụgide ma ọ bụ abụọ, na na ma ọ bụ na-enweghị ejuputa ihe, nke mere na ihe nke workpieces na-njikọ n'etiti atọm na-etolite a. njikọ.Yabụ kedu isi ihe na ọkwa makaigwe anaghị agba nchara?
Kedu ihe electrode na-eji maka ịgbado ọkụ igwe anaghị agba nchara?
1.Stainless ígwè electrodes nwere ike kewaa n'ime chromium igwe anaghị agba nchara electrodes na chromium-nickel igwe anaghị agba nchara.A ga-enyocha ụdị elektrọd abụọ a nke dabara na ọkọlọtọ mba dịka ọkọlọtọ mba GB/T983-2012 si dị.
2.Chromium igwe anaghị agba nchara nwere ụfọdụ mgbochi corrosion (oxidizing acid, organic acid, cavitation) okpomọkụ na-eguzogide na corrosion iguzogide.A na-ahọrọkarị ya dị ka akụrụngwa akụrụngwa maka ọdụ ọkụ, ụlọ ọrụ kemịkalụ, mmanụ ala na ihe ndị ọzọ.Otú ọ dị, ike weld nke chromium igwe anaghị agba nchara bụ n'ozuzu ogbenye, na kwesịrị ịkpachara anya na-akwụ ụgwọ na ịgbado ọkụ usoro, okpomọkụ ọgwụgwọ ọnọdụ na nhọrọ nke kwesịrị ekwesị ịgbado ọkụ electrodes.
3.Chromium-nickel igwe anaghị agba nchara electrodes nwere ezigbo nguzogide corrosion na oxidation resistance, na-eji kemịkalụ, fatịlaịza, mmanụ ala, na ọgwụ ígwè n'ichepụta.Iji gbochie intergranular corrosion n'ihi kpo oku, na ịgbado ọkụ ugbu a ekwesịghị ịdị oke ibu, nke bụ banyere 20% erughị nke carbon ígwè electrodes. The arc ekwesịghị ịdị ogologo oge, ndị interlayers na-mma ngwa ngwa, warara bead ịgbado ọkụ bụ. dabara adaba.
Ihe mgbado ọkụ igwe anaghị agba nchara na ọkwa
A na-anabata ike ọkọnọ nwere njirimara mpụga kwụ ọtọ, a na-ejikwa polarity dị mma maka DC (a na-ejikọ waya ịgbado ọkụ na ogwe adịghị mma)
1.It bụ n'ozuzu kwesịrị ekwesị maka ịgbado ọkụ mkpa efere ígwè n'okpuru 6mm.Ọ nwere njiri mara mma ịgbado ọkụ udi na obere ịgbado ọkụ deformation.
2.The gas nchebe bụ argon na ịdị ọcha nke 99.99%.Mgbe ịgbado ọkụ ugbu a bụ 50 ~ 150A, eruba ọnụego nke argon gas bụ 8 ~ 10L / min, mgbe nke ugbu a bụ 150 ~ 250A, eruba ọnụego nke argon gas bụ 12 ~ 15L / min.
3.The protruding ogologo nke tungsten electrode si gas nozulu bụ ọkachamma 4 ~ 5mm.Ọ bụ 2 ~ 3mm n'ebe ndị na-adịghị mma ọta dị ka fillet ịgbado ọkụ, na 5 ~ 6mm na ebe oghere dị omimi.Ebe dị anya site na nozzle ruo ọrụ anaghị adịkarị karịa 15mm.
4. Iji gbochie porosity ịgbado ọkụ, ọ bụrụ na e nwere nchara na mmanu mmanu na akụkụ nke ịgbado ọkụ, ọ ga-ehicha ya.
5. The ịgbado ọkụ arc ogologo bụ ọkachamma 2 ~ 4mm mgbe ịgbado ọkụ nkịtị ígwè, na 1 ~ 3mm mgbe ịgbado ọkụ igwe anaghị agba nchara.Ọ bụrụ na ọ dị ogologo, mmetụta nchebe agaghị adị mma.
6. Mgbe butt-bottoming, iji gbochie azụ nke ala weld bead ka ịbụ oxidized, azụ nwekwara mkpa ka e chebe ya site na gas.
7. Iji mee ka argon gas na-echebe nke ọma ịgbado ọkụ ọdọ mmiri na ikwado na ịgbado ọkụ ọrụ, center akara nke tungsten electrode na workpiece na ịgbado ọkụ ebe kwesịrị n'ozuzu ịnọgide na-enwe akụkụ nke 80 ~ 85 °, na n'akuku n'etiti filler waya na elu nke workpiece kwesịrị ka obere ka o kwere mee.N'ozuzu, ọ bụ ihe dịka 10 °.
8. Ikuku ikuku na ikuku.Ebe ikuku dị, biko mee ihe iji gbochie ụgbụ, ma mee usoro ikuku ikuku kwesịrị ekwesị n'ime ụlọ.
