ENGINEERING ANALYSIS

Steel Fabrication:

Steel tubes are up to 1.650 meters diameter in 2 meter sections and up to 6 are welded together to have 12 meter long outriggers. The steel is made of AH32 steel.

We used Electric welding for tacks and small welds. MIG for structural.

The pipes were assembled with 7018-H4R at 1/8 inch thickness. For the root and fill pass, the pipe was preheated and the FCAW process was applied with E71T-1CM 0.35 dual shiel tubular wire. Shielding gas mixture 75% argon and 25% Co2 was used. The MIG process was used with solid wire ER70S-6 0.35 with a mixture of shielding gas of 75% argon and 25% CO2.
