Metal ịgbado ọkụ, uru na ụdị

Ọtụtụ-eji ewu na ezinụlọ natara welds. metal ịgbado ọkụ nwere uru n'elu ụzọ ndị ọzọ nke isonyere akụkụ:

- ihe ego, ọ dịghị mkpa na-eji ọzọ fasteners;

- pụrụ ịdabere na-ewu na-enwetara, niile welded nkwonkwo na-haziri maka ẹdude ibu;

- ọzọ ò ojiji nke ihe onwunwe adịghị mkpa dị ka nēfe ebu, iru sprues, na na machining kwesịkwara iburu n'uche na-enye n'ihu;

- mbenata mgbagwoju nke n'ichepụta akụkụ na owuwu nke ọnụ n'ihi na ò ojiji nke chọrọ ọkpụrụkpụ nke metal.

Metal ịgbado ọkụ a rụrụ dị ịgbado ọkụ ihe: electrodes, waya mkpara. Dabere n'ihe na-welded, ha nwere ike mere nke carbon steels, aluminum alloys, tungsten na-abụghị consumable electrode, na electrodes maka ejikọta ígwè.

The isi ụdị nke welds: akuku, bungy, tees, butt, Splices, na nkwụnye (kọntaktị ịgbado ọkụ).

The ụzọ nke na-eme ka ogige:

- ntuziaka ịgbado ọkụ nke metal - nkịtị ma ọ bụ nke ukwuu penetration;

- akpaghị aka - submerged aak, na carbon dioxide, electroslag;

- ọkara akpaka - na echebe gas na submerged aak.

Dị ka usoro nke nkwonkwo ebe na ohere, ha na-n'ịnyịnya, akwụ ọtọ, kwụ na ala ala. Na ogologo - siri ike na gbajiri. Na plọg na intermittent welds na-eji na njikọ na-anaghị achọ oru. Siri ike nkwonkwo na-eji ma ọ bụrụ na chọrọ site imewe akwụkwọ. Mgbe ọ dị mkpa ịrụ a zuru penetration, na Weld anwale leaks site ultrasonic usoro, ma ọ bụ kerosin.

butt-ịgbado ọkụ metal nke ruo 8 mm na ọkpụrụkpụ na-rụrụ na-enweghị ịcha n'ọnụ ya. N'elu bụ unilateral ma ọ bụ bilateral ọnwụ n'ọnụ, dabere na ihe onwunwe ọkpụrụkpụ na ihe owuwu ọrụ.

Mpempe akwụkwọ metal ịgbado ọkụ a rụrụ longitudinal ma ọ bụ transverse seams mbụ obụpde nke abụọ na mgbe mbụ. The onuete na-etinyere si n'elu ala zere mwubata nke mgbe n'itinye. The gaps n'etiti ndị ọcha kwesịrị banyere 1 mm.

Mgbe a mkpa metal ịgbado ọkụ, iji zere deformation nke ihe onwunwe, rụrụ nchụpụ n'ike zanevolivanie Ọdịdị. Tụkwasị na nke a, ị ga-akpa itinye a na-aga n'ihu onuete, na mgbe ahụ jupụta na efu ohere. Iji gbochie ọkụ nke metal, na nkwonkwo mkpa nditịm ịnọgide na-enwe na nkà na ụzụ na iji kwekọrọ ekwekọ kwesịrị ekwesị electrodes ma ọ bụ waya n'obosara. All butt welds na-rụrụ n'elu mmepụta rails.

N'ihi na akpaka ịgbado ọkụ nke ọjà, ducts, plasma surfacing mpempe akwụkwọ a na-eji. Ọkpụrụkpụ nke welded ọcha - si 0,5 mm 5 mm. Basic ihe maka plasma technology - igwe anaghị, kpaliri, nwayọọ ígwè.
