(QW-410.64) Thermal Processes used in fabrication: Select this box if Thermal Processes are to be used during fabrication.
QW-410.81) Tubes expanded prior to welding: Select this box if the tubes are expanded prior to welding.
Number of electrodes: For hardface and overlay welds, enter the number of electrodes.
...
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.
Bead Width: For SMAW, SAW, GMAW, FCAW, GTAW, and PAW welds, this field is used to track the bead width that can be used to determine heat input.
| The following fields are unique to PAW processes. |
|---|
Melt-in to keyhole: Indicate whether the Melt-in or the keyhole technique was applied. Melt-in is a technique in which the intensity of the concentrated heat is adjusted so that a weld pass can be produced from filler metal added to the leading edge of the molten weld metal. In Keyhole welding, a concentrated heat source penetrates partially or completely through a work piece, forming a hole (keyhole) at the leading edge of the weld pool. |
Orifice diameter: Enter the diameter of the plasma torch-arc constricting orifice. |
| Constricted arc type: For hardface and overlay processes, indicated the type of constricted arc used. |
| The following fields are unique to OFW processes. |
|---|
| Flame characteristics: Describe the characteristics of the flame. |
| Welding technique: Indicate the welding technique used for this test. |
| Tip size: Enter the size of the torch tip. |
| Torch type: Enter the type of torch. |
Notes/Additional Filler Metal
...
Flux from recrushed slag: For SAW processes, indicate whether or not the flux was from recrushed slag.
| The following fields are unique to PAW overlay or hardface processes. |
|---|
| Powdered metal -- Type: Enter the type of powdered metal used in this test. |
| Feed rate: Enter the feed rate of the powdered metal. |
| Particle size: Indicate the particle size of the powdered metal. |
