6010 is high penetration electrode. Root gap shall be 1-1.5mm. Otherwise undercut will come.

Dear all

I am working with Gas export pieline in Kazakhstan

We are using 6010 electrode for root

& 8010 for fill cap

 

we are facing the problem with root undercut

 

Actually on the basis of radiography ( ISO 13847 ) doesnt ask to cmpareason of density with parent metal It says only about length

 

Please guide

Could you please guide
