[MW:4679] Recommandation of Welding Process for Offshore Pile and Transition Piece weld joints

Dear Friends ,
 
I would like to know if any other welding process is in use for welding Pile  Pile joints and Transition joints in offshore Internationally to speed up the welding Process .
 
The common one is SMAW welding and FCAW welding
 
With SMAW welding :- 
 
  • It take long time upto 8 hours for welding the joints and in some case if the thickness is more it goes to 10 hours , affecting the barge time
  • Consumable handling required
  • Maintaining of Electrode Temp is required
  • 8 to 9 welders are required
With FCAW welding
  • Welders Skill required
  • Few Spec does not allow
May know if any other Automatised or Semi Automatise welding Process can be used .
 
Is it possible to use SAW  Welding Process by changing the joint configuration as show in the figure attached
 
Regards
 
Sujeet
