ASME PQR - Process

Each process selected in the Process Information section will have its own tab. The type of process selected will determine which fields will be present.

Filler Metal (QW-404)

AWS classified filler metal: Select this box to indicate that the material used has been classified by AWS.

AWS classification: Enter the AWS Classification of the filler metal. If the filler metal is selected through the Filler Metal Browser, this will be entered automatically.

SFA: Enter the SFA number of this filler metal. If the filler metal is selected through the Filler Metal Browser, this will be entered automatically.

F-Number: Enter the F-Number of this filler metal. This field will be automatically completed if a filler metal is selected from the Filler Metal Browser.

Weld Thickness: Enter the actual deposited weld metal thickness for this process.

Pass > 1/2" (or 13.0mm): Select this box if the weld pass is greater than a half inch or 13 mm. This field only applies to SMAW, SAW, EGW, and GMAW/FCAW groove and fillet welds.

Trade name: Enter the trade name for this filler metal. This field is essential if the filler metal is not AWS classified.

Product form: Describe the product form of this filler metal. This only applies to GMAW/FCAW, GTAW, EGW, and PAW processes.

Consumable insert: The filler metal that is placed at the joint root before welding with the purpose of becoming completely fused into the root so it is part of the weld. If a consumable insert was used, describe it here. This field only applies to GTAW and PAW groove and fillet welds.

Flux: Material used to dissolve, prevent, or facilitate the removal of oxides or other undesirable surface substances. It may act to stabilize the arc or shield the molten pool, but it may not evolve shielding gas by decomposition. If a flux was used for weld penetration, enter the flux name here. This field only applies to GTAW, 2001 code or later.

Position/Gas

Position (QW-405)

Position: The relationship between the weld pool, joint, joint members, and weld heat source during welding. Select the position used when qualifying the weld.

Gas (QW-408)

Gas & Flow rate: Enter the shielding gas, backing gas, and trailing gas and their appropriate flow rates in the respective fields. The gas can also be selected from the drop-down menu. PAW processes will also have fields for plasma gas; PAW hardface and overlay processes will have additional fields for powder feed gas.

Electrical/Weld Details

Electrical (QW-409)

Use Instantaneous Power: As used for waveform controlled welding, this method is the determination of power or energy using the product of current and voltage measurements made at rapid intervals. These capture brief changes in the welding waveform. 

Select the box to use this method to calculate the value for the "Heat input" field.

Current/polarity: Enter the current type and polarity. This may also be selected from the drop-down.

Transfer mode: For GMAW/FCAW processes, select the transfer mode.

Tungsten type: For GTAW or PAW processes, indicate the type of tungsten electrode used.

Tungsten size: For GTAW or PAW processes, enter the size of the tungsten electrode used.

Pulsed current: For GTAW processes, enter the current for the pulse of the arc.

Heat input: Calculated using either Instantaneous Power or an equation that requires the inputs of voltage, amperage, and travel speed.

This field is only essential when impact testing is selected.

Weld Details

In most cases up to 3 Weld Details can be added per process on a ASME Section 9 PQR.

Electrode/wire size: Enter the electrode or wire sizes actually used for this process. If the electrode or wire size is not an essential variable, enter a value in these fields and place comments about the electrode on a note line. A note about the size may also be placed in these fields. For example, 1/8 (2.4 mm) may indicate the use of either a 1/8-inch or a 2.4-millimeter electrode.

Amperage used: Enter the amps recorded for the electrodes or filler metals used with this process.

Voltage used: Enter the voltage used in the test.

Wire feed speed: For semiautomatic, automatic, or machine processes, enter the speed of the wire feed used in the test.

Travel speed: Enter the travel speed of the test in inches per minute (ipm) for English units or millimeters per minute (mm/min) for metric.

Weld Details IP

These fields will appear when "Use Instantaneous Power" is selected in the Electrical section.

Calculate Energy: Select this box to enable the "Power" and "Arc Time" fields; values in these fields will be used to calculate energy. When this box is cleared, the "Energy" fields will be available for input instead.

Power (J/s or W): Used to calculate "Heat input." This is required when using Instantaneous Power and when energy is not determined.

Energy (J): Used to calculate "Heat input." This is required when using Instantaneous Power.

Arc Time (s): Used to calculate "Heat input." This is required when using Instantaneous Power and when energy is not determined.

Weld Bead Length: Used to calculate "Heat input." This is required when using Instantaneous Power.

Technique (QW-410)

Bead type: Select the bead type. A stringer bead is made without appreciable weaving motion; a weave bead is made with transverse oscillation.

Nozzle/gas cup size: A gas cup is the device at the exit end of the torch or gun that directs shielding gas. Enter the actual size of this device used during the weld test.

Contact tube to work: Enter the contact tube to work distance recorded during testing. This field only applies to SAW, EGW, and GMAW/FCAW processes.

(QW-410.64) Thermal Processes used in fabrication: Select this box if Thermal Processes are to be used during fabrication.

This field applies to PAW overlay and hardface processes and to GTAW overlay and hardface processes for Code year 2003 and later.

Passes per side: For groove and fillet welds, select single pass, multiple pass, or a combination of the two.

Weld environment: Indicate whether the welding was performed in a closed chamber or performed outside without a closed chamber. This field only applies to GTAW and PAW groove and fillet welds on P-No. 51 through P-No. 53 base metals.

Single/multiple layers: For hardface and overlay processes, select either single or multiple layers.

Supplementary device used: For SAW overlay welds, select this box to indicate that a supplementary device was used to control the magnetic field acting on the weld puddle.
