03. Usoro ọrụ
Tupu ịgbado ọkụ, a ga-ehichapụ elu nke workpiece. Ngwọta ihicha a na-ejikarị bụ pickling, ya bụ, a na-ebu ụzọ pịnye ya na sulfuric acid dị ọkụ na mkpokọta 10%, wee saa ya na mmiri ọkụ. Usoro ịgbado ọkụ a kapịrị ọnụ bụ nke a:
(1) Na-eri nri na workpiece nkwonkwo n'etiti elu na ala electrodes nke ntụpọ ịgbado ọkụ igwe na mwekota ya;
(2) Mgbe a na-etinye ọkụ eletrik, a na-ekpo ọkụ n'elu kọntaktị nke abụọ workpieces, gbazee akụkụ, na a nugget guzobere;
(3) Nọgide na-enwe nrụgide mgbe ike kwụsịrị, nke mere na nugget a wụrụ awụ na-eme ka ọ dị jụụ ma sie ike n'okpuru nrụgide ịmepụta nkwonkwo solder;

04.Ihe na-emetụta
Isi ihe na-emetụta àgwà ịgbado ọkụ gụnyere ịgbado ọkụ ugbu a na oge ume ike, nrụgide electrode na shunt, wdg.
1. Welding ugbu a na ike-na oge
Dị ka nha nke ịgbado ọkụ ugbu a na ogologo nke ike-na oge, ntụpọ ịgbado ọkụ nwere ike kewara abụọ ụdị: ike nlele na nro nlele. Nkọwapụta nke na-agafe nnukwu ugbu a n'ime obere oge ka a na-akpọ nkọwa siri ike. Ọ nwere uru nke nnukwu arụpụtaghị ihe, ogologo ndụ electrode, na obere nrụrụ nke weldment, ọ dịkwa mma maka ịgbado ọla na ezigbo ọkụ ọkụ. A na-akpọ ihe nlele nke na-agafe obere ihe ugbu a n'ime ogologo oge dị nro, nke na-arụ ọrụ dị ala ma dị mma maka ịgbado ọla ndị na-emekarị ka ọ sie ike.
2. Electrode mgbali
N'oge ịgbado ọkụ ntụpọ, a na-akpọ nrụgide electrode nrụgide na-etinye na weldment. Ekwesịrị ịhọrọ nrụgide electrode nke ọma. Mgbe nrụgide ahụ dị elu, enwere ike ikpochapụ oghere na nkwụsịtụ nke nwere ike ime mgbe nugget siri ike. Otú ọ dị, a na-ebelata nguzogide na njupụta ugbu a nke electrode, na-eme ka ikpo ọkụ na-ezughị ezu nke weldment na mbelata na dayameta nke nugget. Ike nke nkwonkwo solder na-ebelata. Enwere ike ịhọrọ oke nrụgide electrode dabere na ihe ndị a:
(1) Ihe nke weldment. Nke dị elu elu ike okpomọkụ nke ihe onwunwe. Nke ka ukwuu nke nrụgide electrode chọrọ. Ya mere, mgbe ịgbado ọkụ igwe anaghị agba nchara na okpomọkụ na-eguzogide, a ga-eji a elu electrode mgbali karịa mgbe ịgbado ọkụ obere carbon ígwè.
(2) welding parameters. Ka nkọwapụta ịgbado ọkụ siri ike, ka nrụgide electrode ka ukwuu.
3. Ntughari
N'oge ịgbado ọkụ ntụpọ, nke ugbu a na-eru n'èzí isi ịgbado ọkụ na-akpọ shunt. Shunt na-ebelata ugbu a na-agafe na mpaghara ịgbado ọkụ, na-eme ka ikpo ọkụ na-ezughị ezu, na-eme ka mbelata dị ukwuu na ike nke nkwonkwo solder na-emetụta àgwà ịgbado ọkụ. Ihe ndị na-emetụta ogo ntugharị ahụ gụnyere akụkụ ndị a:
(1) Ọkpụrụkpụ weldment na oghere ebe ịgbado ọkụ. Ka ebe dị anya n'etiti nkwonkwo solder na-abawanye, nkwụsị nke shunt na-abawanye na ogo nke shunting na-ebelata. Mgbe a na-eji oghere ebe a na-ahụkarị nke 30 ruo 50 mm, shunt ugbu a na-akwụ ụgwọ maka 25% ruo 40% nke ngụkọta ugbu a, na ka ọkpụrụkpụ nke weldment na-ebelata, ogo nke shunting na-ebelatakwa.
(2) Elu ọnọdụ nke weldment. Mgbe enwere oxides ma ọ bụ unyi n'elu welding, nguzogide kọntaktị n'etiti welding abụọ na-abawanye, na ugbu a na-agafe ebe ịgbado ọkụ na-ebelata, ya bụ, ogo nke shunting na-abawanye. Enwere ike ịchacha ihe a na-arụ ọrụ, sandblasted ma ọ bụ na-egbu maramara.
05.Nchekwa nchekwa
(1) Mgbanwe ụkwụ nke igwe ịgbado ọkụ kwesịrị inwe mkpuchi nchebe siri ike iji gbochie ịgbalite mberede.
(2) Ebe a na-arụ ọrụ kwesịrị ịbụ nke nwere ihe mgbochi iji gbochie ọkụ ọkụ na-arụ ọrụ ka ọ na-efe efe.
(3) Ndị welders kwesịrị iyi ugogbe nchekwa dị larịị mgbe ha na-agbado.
(4) Ebe a na-edobe igwe ịgbado ọkụ kwesịrị ka akpọọ nkụ, a ga-ejikwa efere mgbochi skid kpuchie ala ya.
(5) Mgbe arụchara ọrụ ịgbado ọkụ ahụ, a ga-ebipụ ọkụ eletrik, na mgbanaka mmiri jụrụ oyi kwesịrị ịgbatị maka 10 sekọnd tupu emechi. Mgbe okpomọkụ dị ala, a ga-ewepụ mmiri a na-akwakọba n'ime mmiri iji gbochie oyi.
