Hi Vikas,

 

Following are the recommendations of ASME Sec-IX.

 

·         QW-405.2--Vertical-uphill progression (e.g., 3G, 5G, or 6G position) qualifies for all positions.

 

·         QW-404.4-For hard-facing and corrosion-resistant weld metal overlay, qualification in the 3G, 5G, or 6G positions, where 5G or 6G pipe coupons include at least one vertical segment completed utilizing the up-hill progression or a 3G plate coupon is completed utilizing the up-hill progression, shall qualify for all positions.

 

Basically  for procedure qualification 3G- up qualifies for all position. However same is not true for performance qualification..

 

Thanks.

Hi

 

AS per SEC IX, If one WPS is qualified in 3G position for what other positions it is qualified (please give the reference clause).

 

Thanks
