Contemplated configurations and methods are directed to non-destructive ultrasound testing of stainless steel materials, and especially materials in a difficult-to-reach position, in which a phased array probe is operated using longitudinal waves, wherein the probe is further operated at an angle th

대표청구항 ▼

What is claimed is: 1. A method of testing weld integrity of a weld in a stainless steel material, comprising: providing an ultrasonic phased array probe, wherein the probe is operated such that a beam angle is varied, and wherein the probe is operated in longitudinal wave mode; placing the probe onto a surface of a stainless steel material to be tested at an angle such that by variation of the beam angle in longitudinal wave mode substantially all of the material below the surface is scanned; and operating the probe to allow scanning for a potential flaw in the stainless steel material, such that the flaw is detectable at a depth of at least 25 mm. 2. The method of claim 1 wherein the beam angle is varied between 20 degrees and 70 degrees. 3. The method of claim 1 wherein the probe angle is between 60 degrees and 80 degrees. 4. The method of claim 1 wherein the material below the surface comprises at least one of a branch connection fitting, and a full penetration groove weld, optionally with fillet reinforcement. 5. The method of claim 4 wherein the branch connection fitting is between a beveled outlet fitting and at least one of a static casting header and a modified tee. 6. The method of claim 1 wherein the flaw is selected from the group consisting of a crack, a lack of fusion, an incomplete penetration, an undercutting, a surface porosity, and an exposed slag inclusion. 7. The method of claim 1 wherein the material below the surface has a thickness of at least 30 millimeter. 8. The method of claim 1 wherein the material below the surface comprises stainless steel suitable for high-pressure operation. 9. A method of instructing a person to detect a potential flaw in a weld of a stainless steel material, comprising: providing an information to use an ultrasonic phased array probe to test weld integrity of a weld in a stainless steel material, wherein the probe is configured and operated such that a beam angle is varied; providing information to operate the probe in longitudinal wave mode; providing information to place the probe onto a surface of a stainless steel material at an angle such that by variation of the beam angle in longitudinal wave mode substantially all of the material below the surface is scanned; and providing information to allow scanning for a potential flaw in the stainless steel material, such that the flaw is detectable at a depth of at least 25 mm. 10. The method of claim 9 wherein the beam angle is varied between 20 degrees and 70 degrees. 11. The method of claim 9 wherein the probe angle is between 60 degrees and 80 degrees. 12. The method of claim 9 wherein the material below the surface comprises at least one of a branch connection fitting, and a full penetration groove weld, optionally with fillet reinforcement. 13. The method of claim 12 wherein the branch connection fitting is between a beveled outlet fitting and at least one of a static casting header and a modified tee. 14. The method of claim 9 wherein the flaw is selected from the group consisting of a crack, a lack of fusion, an incomplete penetration, an undercutting, a surface porosity, and an exposed slag inclusion. 15. The method of claim 9 wherein the material below the surface has a thickness of at least 30 millimeter. 16. The method of claim 9 wherein the material below the surface comprises stainless steel suitable for high-pressure operation.
