Foreword
This standard replaces GB/T 5193-1985 "titanium and titanium alloy products ultrasonic flaw detection method."
This standard compared with GB/T 5193-1985, mainly in the following changes.
--- Expand the scope of cross-sectional thickness greater than titanium and titanium alloy products, ultrasonic flaw detection of 6mm;
--- Method category increased 6mm ~ 45mm flooding bars should be preferred focusing method;
--- Increases the surface roughness R Rao ≤3.2μm;
--- For the A-mode pulse reflection equipment requirements to meet the JB/T 10061 "A-mode pulse reflection type ultrasonic probe
Injury general technical conditions "requirements;
--- Increasing the diameter of 8mm ~ 20mm, operating frequency of 2.5MHz ~ 5MHz duals, recommended for 6mm ~
20mm thick planar contact method product testing;
--- Increased when both parties agree to allow the use of frequencies below 2.5MHz or a particular type of probe;
--- Burial depth of the flat bottom hole made appropriate changes;
--- Modify the status of the device during testing requirements;
--- Modify the requirements immersion testing pulse repetition frequency;
--- For no alarm system, manual scan, scan speed recommended, to not more than 127mm/s;
--- Increased suppression control requirements;
--- Modify part of Table 2;
--- Level of acceptance increases the Notes;
--- Increased inspection records and reports.

JB/T 10061 A-mode pulse reflection type ultrasonic flaw detector General technical requirements
3 Requirements
3.1 Objective
Mainly for internal flaw detection of titanium and titanium alloy products, such as cracks, holes, loose and other exposed or exposed to the surface
Discontinuity tissue.
3.2 Method category
This standard specifies the use of ultrasonic flaw detection pulse longitudinal wave reflection method. If necessary, may also be agreement between shear wave or other
Type, immersion or contact method can be. 6mm ~ 45mm flooding bars should be preferred focusing method.
