All and all the meeting was very productive and there was a lot of interesting discussions. The group wants to develop a much larger repair welding section which will be more descriptive to the user and give guidance on how to qualify repair procedures.
The remainder of the day was for the group working on repair welding. Most of the discussions were on allowing retesting of some mechanical tests during procedure qualification. During the second day, the qualification subcommittee reviewed their proposed changes. These changes would mainly consist of clarifying or adding essential variables (heat input range, weld deposition, carbon equivalent), clarifying the intent of welder qualification and the inclusion of procedure and welder requirements for weld deposition repairs.
