GB /T 984 EDCr-A1-03


LY-D502 is lime titanium type hardfacing electrode.Both AC and DC can be applied. Welding arc is stable and slag is easy to remove when welding.It shows good performance in welding.


It is a kind of generality surface electrode and it is suitable for hardfacing the axles and valves fabricated by carbon steel or alloy steel ,of which work temperature is below 450℃.

a.Welding electrodes must be baked for 1 hour at the temperature of 150±10℃ before welding.
b.Before welding ,the hardfacing weld metal must be cleared away impurities ,such as rust,oil,moisture etc.
c.Before welding,the welded pieces should be preheated to the temperature above 300℃ , and corresponding hardness can be obtained  with different temperature heat-treatment after welding.
