Re: [MW:4688] Recommandation of Welding Process for Offshore Pile and Transition Piece weld joints

Dear Sujeet,

                    With my practicle experience we used SMAW & GTAW only for Offshore platform (Piles) . The joint configuration what you have shown is correct  but it shall satisfy your Strength Requirement. If so you have to carry out Destructive test to ensure.

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
