Dear Reader

We have to carry out butt welding in a plate of about 6mm thick for a weld length of 1Mtr on both sides for every 3Mtr of 15 Mtr Structure. The plate was bend in such a way ( in a U Shape) that for a particular length of 100mm weld is assessible from only one side.

The Process we qualified is SMAW.
The joint employed is Square Groove.

What are the other options available.
My friend suggest that FCAW process will be a better option since welding from one side is sufficient due to good penetration.

Can any one kindly advise
