What is ASME IX in welding?
ASME section IX is a part of the ASME boiler pressure vessel code that contains the rules for qualifying welding procedures and welders. It is also used to qualify welders and procedures for welding to ASME B31.
Which section of the ASME Code covers qualification of welders?
Section IX
• QW-100 GENERAL “Section IX of the ASME Boiler and Pressure Vessel Code relates to the qualification of welders, welding operators, brazers, and brazing operators, and the procedures that they employ in welding and brazing. . . “
Which welding test position is a qualification for all positions per the ASME IX code?
the horizontal, vertical, and overhead positions shall qualify for all positions. Qualification in the inclined fixed position, 6G, shall qualify for all positions.
Which test is required for fillet weld procedure qualification as per ASME Sec IX?

ASME IX requires pressure containing fillet welds to be qualified by a butt weld procedure qualification test.
What is P number in ASME?
Base Metals: The P Number This number is used to group similar Base Metals, allowing qualification of an entire selection versus qualification of just one. These base metals are grouped by material and assigned P Numbers based on what material they are.
What is the difference between PQR and WPS?
WPS is welding procedure specification whereas PQR is procedure specification record. These are some of the significant and mandatory documents especially to ensure that the welds comply with the rules.
What is weld test?
Weld testing is a greatly specialised discipline requiring skill and expertise, with testing methods being a central aspect of weld procedures for a multitude of construction and fabrication processes.

What is ASME certified welder?
The ASME doesn’t certify welders , but it does certify welded products such as boilers, bioprocessing equipment and nuclear components. You need education or training from an accredited school to work on certified products. The ASME is a mechanical engineering association that certifies products that meet its standards.
What does a welder qualification test verify?
The welder qualification test (WQT) is performed to determine whether the welder or the welding operator can produce a sound weld or not. Each welder or welding operator shall be qualified for each welding process to be used during production (or fabrication) welding.
