| Description |
This is a Joint
Industry Project (JIP). To determine the state-of-the-art of underwater wet welding and
how the technology can be advanced by the developmental program. This will be done by
making welds with the best combination of experimental electrode, optimum multiple
temper-bead technique, and power source/auxiliary equipment. |
| Progress |
Complete. Twelve flux
coating compositions were designed for testing on two core rods. Experimental electrodes
were used to perform multiple pass welds in 33 feet of water. Tests performed on the welds
included bend testing, hardness measurements, chemical analysis, and X-ray radiography.
Four welds were selected for further testing. The weld data was carefully analyzed for
better understanding of the interaction between flux ingredients and weld properties. |
