Re: [MW:34444] Clarification regarding T,K,Y JOINTS WELDING

Hi Uma shankar,

1) 6G - welder - No 

2) 6GR welder -Yes, TKY -joints are partial penetration groove joints with limited access during welding.

                          R stands for restriction ring during performance qualification. 

3) TKY NDT   - Before welding - UT Lamination check.

                         After Welding- Wet magnetic particle testing & Angle probe-Ultrasonic testing. 

4) Repair Rate- Only applicable for Full penetration groove weld & butt weld only (Category A-CategoryA,B,C)

 

Regards 

Vinoth
