Emmanuel: e ji mara na nhazi ọkwa

Manual aak ịgbado ọkụ a na otú aha ya bụ n'ihi na ihe niile chọrọ omume ọkachamara welder aka. Ọ bụ maka na-akpali ma na-enyere aak, aak ije nke na kọntaktị na achọrọ nkeji, ọkọnọ nke ọhụrụ electrodes kama eji. Weld quality na-adabere na nkà nke welder. Mkpa ngwa ngwa edita aak, anya nyochaa ka ogologo ya dị otu, nakwa dị ka na-emepụta a edo ịgbado ọkụ nke abụọ.

Emmanuel nwere otu nhazi ọkwa. Ka ihe atụ, dị ka ọnụ ọgụgụ nke electrodes eji Weld iche otu ma ọ bụ abụọ electrodes, na multi-electrode. E nwere atọ-adọ na-alụbeghị di-adọ aak, nke ugbu a agwa nwere ike AC ma ọ bụ DC.

Ugbu nile ịgbado ọkụ na nwetụ ma ọ bụ kpọmkwem ugbu a iji a consumable electrode. N'ezie, e nwere ọtụtụ ụzọ dị iche iche jikọọ ibe site ịgbado ọkụ. Dị ka ihe atụ, na-etolite dị iche iche nke nkwonkwo (flanged n'ọnụ). Ntọt arụpụtaghị na-atụ aro iji ihe electrodes nke okporo osisi, na ịgbado ọkụ nke dị iche iche alloys na-abụghị ferrous ọla bụ tungsten electrodes.

Emmanuel nwere a kpọmkwem n'ichepụta usoro. Mgbe ịgbado ọkụ electrodes n'akụkụ dị iche iche na-eji, nke nwere ike ịbụ consumable na nonconsumable. Ihe mbụ nwere ike mere nke waya na a pụrụ iche mkpuchi. Dị otú ahụ spraying dị mkpa maka a elu ogo kwụsiri ike nke eletriki aak -enye a metal n'elu ụzụ na oxides nke chebe Weld ọdọ mmiri si na mmekọrịta ya na gburugburu ebe obibi, na-echebe aak si n'ógbè nke na mmekọrịta ya na ikuku.

Manual TIG ịgbado ọkụ nwere ike rụrụ na dị iche iche ihere ọnọdụ dị iche iche, haruru. Dị ka ihe atụ, akwụkwọ ntuziaka argon-aak ịgbado ọkụ (na gburugburu ebe nke argon), ịgbado ọkụ na ikuku na t. D.

Dị ka GOST 9466-75, na electrodes na-ekewa n'ime ọtụtụ ụdị.

1. Site oru:

• na carbon ala-alloy bughi steels;
• ígwè alloys;
• okpomọkụ na-eguzogide alloy ígwè;
• elu-alloy bughi steels.

2. Dị ka ụdị na ika:

• maka ihe ọ bụla, ma e wezụga vetikal ntuziaka ịgbado ọkụ;
• maka ala kwụ na na a vetikal ụgbọelu ahụ;
• n'ihi na ala "na ụgbọ mmiri."

6. na polarity nke ịgbado ọkụ ugbu a na-eji:

• kpọmkwem;
• laa azu;
• ọ bụla.

7. ọdịdị nke ịgbado ọkụ ugbu a:

• na-adịgide adịgide;
• AC.

Emmanuel na-egosi na metal nke a na-welded electrodes, ga nwere a chemical mejupụtara kwekọrọ ya chọrọ. The n'ibu e ji mara na n'ihi Weld na Weld metal ọ ga-ada n'ime ime na GOST 9467-75.
