RE: FCAW substitute for SMAW in offshore platforms

[pgos...@rogers.com]

Hi

FCAW is one of the approved welding processes for offshore construction. Often restrictions are imposed by the end user/client. You need to go by what your project/client specification calls for. Here’re some industry specific documents for your reference. GMAW is also a reliable process, however type of the process, i.e.  short circuit/ globular/spray arc decides the application and the effectiveness of this technique.

By and large of the processes are far more accomplished than what they were ,15-20 years ago.

 

Hope these attachments will provide the general insights on your query.

 

Regards.

Subject: FCAW substitute for SMAW in offshore platforms

 

Dear All,

I want to replace SMAW in the fabrication of offshore platforms, top side section.

In this regard, FCAW is selected mainly for most of the welds, to increase the speed of fabrication.

May I know:

1- Is FCAW the right choice? how about GMAW?

2- In the case of FCAW, which electrode with a 3.2mm size is proper for all position welding in offshore platforms? mainly high strength steels

 

Regards,

E.F

GMAW with Pulse is the best choice with 95Ar+5Co2
