AWS A5.5 E8016-B2
Tsanangudzo: R306 inonzi pearlitic heat-resistant steel electrode ine yakaderera-hydrogen potassium coating ine 1% Cr - 0.5% Mo. Zvose AC uye DC zvinogona kushandiswa, uye zvinogona kusungirirwa munzvimbo dzose.Iyo weldment inofanira kunge isati yapisa kusvika 160 ~ 250 ° C isati yave nemoto.
Chikumbiro: Inoshandiswa pakunama Cr 1% - Mo 0.5% simbi inodzivirira kupisa iyo tembiricha yekushanda iri pasi pe520 ℃, senge pombi dzebhailer, midziyo yekumanikidza, vaporizer uye petroleum yekunatsa michina, nezvimwe.
Kemikari yakagadzirwa nesimbi weld (%):
C | Mn | Si | Cr | Mo | S | P |
0.05 ~ 0.12 | 0.50 ~ 0.90 | ≤0.60 | 0.80 ~ 1.50 | 0.40 ~ 0.65 | ≤0.030 | ≤0.030 |
Mechanical zvimiro zve weld simbi:
Test chinhu | Kusimba simba Mpa | Goho simba Mpa | Elongation % | Impact value (J) Normal Temp. |
Guaranteed | ≥540 | ≥440 | ≥17 | ≥47 |
Yazvino inokurudzirwa:
Tsvimbo dhayamita (mm) | 2.5 | 3.2 | 4.0 | 5.0 |
Welding Current (A) | 60 ~ 90 | 90 ~ 130 | 140 ~ 180 | 180 ~ 210 |
Cherechedza:
1. Elekitirodhi inofanira kubikwa kweawa imwe panguva inenge 350 ℃ isati yaitwa welding;
2. Zvinokosha kuchenesa ngura, chikero chemafuta, mvura, uye tsvina pazvikamu zvewelding tisati tasveta.
