Nkọwa: J506NiMA na J507NiMA bụ mmiri na-amịpụta ultra-low hydrogen-coated ala alloy steel electrodes.Igwe a na-echekwara nwere ezigbo plasticity, obere okpomọkụ siri ike na mgbape mgbape, enwere ike ịgbanye ya n'ọnọdụ niile.Ihe mkpuchi ahụ na-eguzogide ọgwụ mmiri.Mgbe emechara electrode na 400 ° C x 1h ma dọba ya na gburugburu ebe obibi nwere iru mmiri ≥ 80% maka awa 4, ọdịnaya mmiri nke mkpuchi ahụ ka na-emezu ihe achọrọ maka ojiji.

Ngwa: Ọ na-eji maka ịgbado ọkụ nke mmanụ nyiwe, ụgbọ mmiri, nsogbu arịa, na ndị ọzọ na owuwu mere nkecarbon ígwè na ala alloy ígwè.

Ngwakọta kemịkalụ nke igwe weld (%):

Njirimara nke igwe weld metal:

Ọdịnaya mgbasa hydrogen nke ọla edobere: ≤5.0mL/100g (gas chromatography ma ọ bụ usoro mercury)

Ọdịnaya mmiri nke mkpuchi electrode: ≤0.30%

Nyocha x-ray: akara ule

Akwadoro ugbu a:

Mara:

1. The electrode ga-abụọ maka 1 hour na 350 ~ 400 ℃ tupu ịgbado ọkụ ọrụ;

2. Ọ dị mkpa iji kpochaa nchara, ọnụ ọgụgụ mmanụ, mmiri, na adịghị ọcha na akụkụ ịgbado ọkụ tupu ịgbado ọkụ;

3. Jiri obere arc arụ ọrụ mgbe ịgbado ọkụ.Ụzọ ịgbado ọkụ dị warara kwesịrị ekwesị.
