Respected experts ,

Happy Sunday to all. 

  A  48 " tubular having 25 mm thickness we made a single bevel butt joint. 

The root & Hotpass  is welded with GTAW and fill up and capping is welded with SMAW. 

My query is that, 

Is back welding  is required or not . If required , please tell the procedure of back welding.

I mean to ask ,

1. which welding process should I use GTAW or SMAW for back welding. ? 

2 . With back gouging or without  back gouging. ?
