Low Hydrogen Electrods

[Mahmood Al-Hinai]

Dear all experts,

If Low Hydrogen Electrods kept directly in a holding oven without backing, and later on it was observed, so how to rectify?

Shall be scraped or backed?

The question is not clear 

Pl elaborate the query

As you know, Low hydrogen Electrods shall be baked (350 degree for 2 hours), but in this case the workshop supervisor didn't bake them, instead of that, he kept them directly in holding oven. 

So shall these electrods scrapped or baked and used?

Hi, Good day,

 

When it comes to baking, you need to maintain the backing oven temperature 260-430 degrees Celsius. While maintaining a temperature of 120 degrees Celsius is for holding purposes,. At 120 degrees Celsius, the flux coating does not experience any significant heat impact, which can’t potentially lead to flux damage, baking requires a higher range of 260-430 degrees Celsius.

Considering the above statement you can go for baking.

Pl get the electrodes back to  Stores

Identify these by AWS name.

Segregate fully intact flux covered electrodes 

Carry out baking as per Consumable Mfg  recommendation

After baking is completed transfer to Holding oven 

issue to Production as per  Consumable Slip Request as required

Make a record in baking  , Holding register 

Thanks
