Kufotokozera: R306 ndi pearlitic zitsulo zosagwira kutentha kwa electrode yokhala ndi mpweya wochepa wa hydrogen potaziyamu womwe uli ndi 1% Cr - 0.5% Mo. Onse AC ndi DC angagwiritsidwe ntchito, ndipo amatha kuwotcherera m'malo onse.Kuwotcherera kuyenera kutenthedwa mpaka 160 ~ 250 ° C musanayambe kuwotcherera.
Ntchito: Ntchito kuwotcherera Cr 1% - Mo 0,5% kutentha zosagwira zitsulo amene ntchito kutentha m'munsimu 520 ℃, monga mipope kukatentha, zotengera kuthamanga, vaporizers ndi zida zoyenga mafuta, etc.
Chemical zikuchokera weld zitsulo (%):
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 |
Zimango za weld zitsulo:
Yesani chinthu | Kulimba kwamakokedwe Mpa | Zokolola mphamvu Mpa | Elongation % | Mtengo (J) Normal Temp. |
Zotsimikizika | ≥540 | ≥440 | ≥17 | ≥47 |
Zomwe tikulimbikitsidwa:
Ndodo diameter (mm) | 2.5 | 3.2 | 4.0 | 5.0 |
Welding Current (A) | 60-90 | 90-130 | 140 ~ 180 | 180 ~ 210 |
Zindikirani:
1. Elekitirodi iyenera kuphikidwa kwa ola limodzi mozungulira 350 ℃ isanayambe ntchito yowotcherera;
2. Ndikofunikira kuyeretsa dzimbiri, sikelo yamafuta, madzi, ndi zonyansa pazigawo zowotcherera musanayambe kuwotcherera.
