Asme Section Ix Thickness Range

Base metal thickness t.

Asme section ix thickness range.

May a new wps be written or revised without specifying weld metal thickness range for each welding electrode e6011 and e7018 with the wps prepared to the 2010 edition of asme section ix code with. Asme sec ix welding procedure and performance qualification. First we need check application for each welding process. After that we check for each element.

Range of thickness qualified for test specimen thickness of 19mm to 38mm are 5 mm min. Also qw 211 states that qualification in plate also qualifies for pipe welding and vice versa. Thickness limits are specified for deposited weld metal. And it will link to table qw 451 1.

Read more at qw 403 8. For test specimen thickness 25 4mm t qualified is 16mm to 50 8mm only. For outside diameter 25 mm or 1 inch to 73 mm or 2 7 8 inch the minimum outside diameter for which the welder gets qualified is 25 mm or 1 inch and maximum outside diameter which he can weld is unlimited. Asme ix does not consider base metal thickness to be an essential variable for welding performance qualification using any of the listed welding processes.

For welding procedure qualification asme ix does not regard pipe diameter as an essential variable and thus procedure qualification testing using a particular pipe diameter will qualify pipe of any other diameter. Qw 403 6 qw 403 8 and qw 403 10 material thickness was 0 75 in. Qw 403 9 no single weld pass in the qualification weld was greater than 1 2 in. However if your wps pqr with impact test the range base metal thickness qualified is t or 16mm whichever is less as per qw 403 6.

Consequently no limitations are specified for the range of base metal thickness qualified by a particular qualification test weld.
