Low Alloy Steel Welding Electrode
J557SLA, J557SLB
GB/T E5515-G
AWS E8015-G
Kufotokozera: Awa ndi sodium wochepa wa haidrojeni wophimbidwa ndi elekitirodi yapadera yazitsulo zotayidwa.Gwiritsani ntchito DCEP (elekitirodi yeniyeni yeniyeni), ndipo imatha kuwotcherera m'malo onse ndi ntchito yaifupi ya arc.J557SLA ikhoza kuwotcherera mwachindunji popanda kuchotsa wosanjikiza wopangidwa ndi aluminiyamu pamtunda musanawotchere.Koma J557SLB iyenera kuchotsa wosanjikiza wopangidwa ndi aluminiyamu pamtunda musanawotcherera.
Ntchito: Amagwiritsidwa ntchito powotcherera zitsulo zotayidwa pansi pa dzimbiri la hydrogen sulfide, sulfure, ammonia, ammonium bicarbonate ndi nayitrogeni wa haidrojeni ndi kutentha kwa ntchito pansi pa 540 ° C.Monga mapaipi opopera, zida zoyenga mafuta, zida za feteleza ndi mapaipi a nthunzi, etc.
Chemical zikuchokera weld zitsulo (%):
C | Mn | Si | Cr | Mo | Al | S | P |
≤0.12 | 0.50 ~ 0.90 | ≤0.50 | ≈0.80 | ≥0.20 | ≤0.055 | ≤0.035 | ≤0.035 |
Zimango za weld zitsulo:
Yesani chinthu | Kulimba kwamakokedwe Mpa | Zokolola mphamvu Mpa | Elongation % | Mtengo (J) Normal Temp. |
Zotsimikizika | ≥540 | ≥440 | ≥17 | ≥49 |
Kuphatikizika kwa haidrojeni muzitsulo zoyikidwa: ≤6.0mL/100g (njira ya glycerin)
Kuwunika kwa X-ray: Ndimapanga
Zomwe tikulimbikitsidwa:
(mm) Ndodo diameter | 2.5 | 3.2 | 4.0 | 5.0 |
(A) Welding Current | 50-80 | 80-110 | 130 ~ 170 | 160 ~ 200 |
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.
