Dear expert,

As per ASME sec-9 , QW-202.2 para C ,

We can proceed SS-316L Material GTAW, FILLET WELD PROCEDURE QUALIFICATION, please suggest me if macro test is applicable for this requirement.

Because my job is only fillet weld small bore socket type welding required for my scope of work.

Fillet‐weld

procedures so qualified may be used for welding all thick-

nesses of base metal for all sizes of fillet welds, and all dia-

meters of pipe or tube in accordance with Table

QW-451.4. Nonpressure‐retaining fillet welds, as defined

in other Sections of the Code, may as an alternate be qual-

ified with fillet welds only. Tests shall be made in accor-

Dear all,

According to ASME Section IX, macro testing is typically not required for fillet weld qualification, regardless of the material specification, including stainless steel like SS 316L. Paragraph QW-202.2(c) of ASME Section IX states: 

"For fillet weld qualification in accordance with QW-202.3, macroscopic examination is not required." This means that macro testing, which involves the preparation and examination of cross-sectional samples of the weld's internal 

structure, is not necessary for the qualification of fillet welds, even when dealing with materials like SS 316L. 

Best regards,
