Prepare, or help prepare, the specimens to be tested.
The Welding Inspector (Test Supervisor) will guide the preparations of the pieces, assembly and periodically check progress to ensure conformity to the Standard.
Fillet Weld Break Test
All Position Qualification
The fillet weld break test is a simpler test that qualifies the welder to weld fillets with the process used during the test. To qualify all positions fillet welding, the welder must pass a separate break test in vertical and overhead positions.
When the welder is only welding fillet welds as is often the case with GMAW (MIG) and GTAW (TIG) processes, a fillet weld break test in all positions instead of a groove test may be the only requirement for the job.
To perform the test, the welder must weld a T joint on one side with a restart near the center as shown in the diagram above. The piece is visually examined and a macrotech test is conducted on one end of the piece. The piece is then broken to visually inspect for complete fusion and to ensure that there are no discontinuities according to the acceptance criteria of the code.
To pass the visual examination prior to the break test, the weld shall present a reasonably uniform appearance and shall be free from overlap, cracks or excessive undercut, as defined by the Code. There shall be no porosity visible on the weld surface.
The broken specimen shall pass if:
The specimen bends flat upon itself.
The fillet weld, if not fractured, has a fractured surface showing complete fusion to the root of the joint, with no inclusion or porosity larger than 3/32 of an inch in greatest dimension.
The sum of the greatest dimension of all inclusions shall not exceed 3/8 of an inch in the 6 inch long specimen.
