[MW:9037] BT

By Materials & Welding

Burn Through in your case I understand was caused with the hot pass.

 

It is caused by electrode diameter or excessive power, thin root, poor handling of electrode, large root gap before root pass, position of job.

 

Not knowing your electrode travel direction I advise you as follows.

 

E6010 produces a strong weld. However to minimise burn through situations, I would recommend a second pass with E6010 on vertical down travel to thicken the root, or, vertical up travel with a smaller E7018 electrode, or, weld a separate plate/pipe with the parameters that is most suitable for you, or, run a welding procedure for anyone to follow.

 

Hope it helps

 

Regards
