| Description |
This is a Joint Industry Project
(JIP). The purpose of this project was to demonstrate the viability of
Homopolar Welding (HPW) in large pipelines. |
| Progress |
The objectives of the research
program developed through course of the year and included improving
toughness of 12-inch pipe welds, assessment of fatigue properties, and API
acceptance. The research effort completed eighteen 3-inch welds, fourteen
12-inch welds, repairs to the 10 MJ homopolar generator, and modifications
to the 12-inch welding fixture. The fatigue study was completed during the
spring of 1998 with the final report submitted to the sponsors on June 4,
1998. No fatigue research is included in the final since no additional
fatigue research was done in the HPWAP. The project is complete. |
