Ultrasonic examination for welds in ferritic materials in Saudi Arabia
TCR Arabia conducts ultrasonic examination for welds in ferritic materials. The UT examnination team adopts a well defined procedure for detecting, locating and evaluating indications within weld metal and heat affected Zone and adjacent base material in Carbon steel and alloy steel welds by pulse echo contact method. The UT examination crew members undertake testing of full penetration weld joints in wrought (Rolled, Drawn, forged, Extruded) or cast materials.

The metallic surface to be tested shall be free from all extraneous materials such as scale, grease, rust, dirt, etc. which may interfere with the testing. The base metal on each side of the weld shall be free of weld spatter, surface irregularities, or foreign matter that might interfere with the examination. As far as the weld metal is concerned, the surface under examination must be prepared as needed to permit examination.

The surface temperature must be monitored and must be such that it does not exceed the probes working temperature range.

Documentation And Reporting Of Test Results
Each inspection shall be reported together with the interpretation of flaws, defects, etc.

Test results shall record the presence, location, type and size where applicable of all relevant defect indications that do not comply with acceptance standard. Where remedial action and re-test is undertaken, this shall be recorded in the identification or test results.

Standard terms and abbreviations shall be used. Where necessary sketches or drawings shall be used to clarify reports.

All reports shall be handed over against signature to the Client representative at relevant stages.

TCR Arabia's responsibility shall be limited to ensuring the integrity of the weld or part within the confines of the ultrasonic test requirements of the governing specification.
