TIG
1.Application :
TIG welding(tungsten argon arc welding) inzira yekugadzira iyo Ar yakachena inoshandiswa sekudzivirira gasi uye tungsten electrodes inoshandiswa semagetsi.TIG welding waya inopihwa mumitsetse yakatwasuka yehumwe hurefu (kazhinji lm).Inert gasi yakadzivirirwa arc welding uchishandisa tungsten yakachena kana activated tungsten (thoriated tungsten, cerium tungsten, zirconium tungsten, lanthanum tungsten) se electrode isinganyunguduke, uchishandisa arc pakati petungsten electrode uye workpiece kunyungudutsa simbi kuita weld.Iyo tungsten electrode haina kunyungudika panguva yewelding uye inongoshanda se electrode.Panguva imwecheteyo, argon kana helium inodyiswa mumuromo wemwenje wekudzivirira.Mamwe masimbi anogonawo kuwedzerwa sezvaunoda.Pasi rose inozivikanwa seTIG welding.
2. Advantage:
Kubatsira kukuru kweTIG welding nzira ndeyokuti inogona weld yakawanda yezvinhu.Kusanganisira workpieces ane gobvu 0.6mm uye pamusoro, zvinhu zvinosanganisira alloy simbi, aruminiyamu, magnesium, mhangura uye alloys ayo, grey cast iron, akasiyana bronzes, nickel, sirivheri, Titanium uye lead.Munda mukuru wekushandisa ndeye welding yezvitete uye zvepakati ukobvu workpieces semudzi wepasi pazvikamu zvakakora.
3. Kuteerera:
A. Shielding gasi rinoyerera zvinodiwa: kana welding ikozvino iri pakati pe100-200A, iri 7-12L / min;kana welding parizvino iri pakati pe200-300A, iri 12-15L/min.
B. Kureba kwetungsten electrode kunofanirwa kuve kupfupi sezvinobvira maererano nemuromo, uye kureba kwearc kunofanirwa kudzorwa pa 1-4mm (2-4mm yewelding carbon steel; 1-3mm yewelding low-alloy simbi. uye simbi isina tsvina).
C. Kana kumhanya kwemhepo kunopfuura 1.0m/s, matanho ekudzivirira mhepo anofanira kutorwa;teerera kumhepo kuti urege kukuvara kune anoshanda.
D. Kunyatsobvisa mafuta, ngura uye mwando tsvina kubva panzvimbo yewelding panguva yewelding.
E. Inokurudzirwa kushandisa DC magetsi ane mawere ekunze maitiro, uye tungsten danda rakanaka kwazvo.
F. Paunenge uchiputira pasi alloy simbi pamusoro pe1.25% Cr, rutivi rwemashure runofanirawo kuchengetedzwa.
MIG
1.Kushandisa:
MIG weldingiri kunyunguduka danda inert gasi rakadzivirirwa welding.Inoshandisa Ar uye mamwe magasi anert segasi guru rekudzivirira, rinosanganisira Ar yakachena kana Ar gasi yakasanganiswa nehuwandu hushoma hwegasi rinoshanda (seO2 pasi pe2% kana CO2 pasi pe5%) yekunyunguduka.Nzira yekushongedza yearc welding.MIG waya inounzwa mumakoiri kana makoiri mumatanda.Iyi nzira yewelding inoshandisa arc inopisa pakati peiyo inoramba ichidyiswa welding waya uye workpiece senzvimbo yekupisa, uye gasi rakaburitswa kubva patochi nozzle rinoshandiswa kuchengetedza arc yekubatira.
2.Advantage:
Yakanakira welding munzvimbo dzakasiyana siyana, uye zvakare ine kukurumidza welding kumhanya uye yakakwira deposition rate.MIG-yakadzivirirwa arc welding inoshandiswa pakukwenenzverwa kwesimbi huru, kusanganisira kabhoni simbi uye alloy simbi.MIG arc welding yakakodzera simbi isina tsvina, aluminium, magnesium, mhangura, titanium, mapiki uye nickel alloys.Arc spot welding inogonawo kuitwa uchishandisa iyi welding nzira.
3.Attention:
A. Iyo yekudzivirira gasi kuyerera kweyero inodiwa 20-25L / min.
B. Kureba kwearc kunowanzodzorwa kunosvika 4-6mm.
C. Kufurira kwemhepo kunonyanya kusanakira kune welding.Kana mhepo inomhanya inopfuura 0.5m/s, matanho ekudzivirira mhepo anofanira kutorwa;teerera kumhepo kuti urege kukuvara kune anoshanda.
D.Kushandiswa kwe pulsed arc current kunogona kuwana yakagadzika spray arc, kunyanya yakakodzera welding ye Stainless steel, thin plate, vertical welding uye surfacing welding.
E. Ndapota shandisa Ar + 2% O2 gasi musanganiswa kuti weld ultra-low kabhoni Stainless simbi, usashandise Ar uye CO2 yakasanganiswa welding simbi.
F. Nyatsobvisa mafuta, ngura uye hunyoro tsvina panzvimbo yewelding panguva yewelding.
