Re: [MW:22001] Welder qualification

Dear Mohit,

 

Although your query lack all necessary information like the applicable code, the type of consumable, materials etc but on a general note, welders qualified for clad restoration are not qualified to weld butt joints but when a welder is qualified on butt weld, the weld is qualified to weld clad restoration if only

 

1. requirement for Chemical composition.

 

2. within the F number of the consumable qualified,

 

3. within the welding position qualified

 

Please refer to ASME IX Art III (See Below)

 

QW-381.3 Alternative Qualification With Groove

Weld Tests.

When a chemical composition is not specified

in the WPS, welders or welding operators who successfully

complete a groove weld performance qualification

test meeting the corrosion

‐resistant overlay bend test requirements

of

QW-163 may be considered qualified for

corrosion

‐resistant overlay welding within the ranges defined

in

QW-350 or QW-360.
