A Macro Examination Must Be Conducted on the Quality Assurance Test Samples To Check For the Following Defects in the Weld Overlay

∙ Laminar defects. 
∙ Porosity. 
∙ Inclusions. 
∙ Fusion with the backing plate. 
∙ Fusion between the different weld layers. For macro examination purposes, the laminar defects and lack of fusion defects may not be longer than 10 mm in length. The sum of the laminar defects and lack of fusion defect lengths may not exceed 10 % of the length of the quality assurance test piece. Weld overlay plates that are subjected to bending or forming during the manufacturing of wear liners, must be subjected to level 1 ultrasonic laminar defect testing. Level 1 ultrasonic laminar defect testing must be performed over 100% of the wear liner surface area. For level 1 ultrasonic laminar defect testing purposes, laminar defects may not be longer than 10 mm in length or 10 mm in width. The sum of the laminar defect areas and lack of fusion defect areas may not exceed 10 % of the wear liner surface area. Level 1 ultrasonic laminar defect testing must be conducted by a NATA accredited level 1 ultrasonic testing technician. A formal testing report must be submitted, in the material data record, for the tests performed. The report should include photos of the wear liners tested, with the defects clearly marked on the mild steel backing plate side. The location and size of the defects must be recorded in the report. Weld overlay wear liners utilized in the following applications will be subjected to level 1 ultrasonic laminar defect testing through the utilization of a 50 mm by 50 mm grid. 
∙ Run of mine bins.
∙ Course ore stockpile hoppers 
∙ Apron feeder hoppers 
∙ Flow expanders in course ore applications. 
∙ Train load-outs. 
∙ Schenk train load-outs. 
∙ Car dumpers Grid pattern testing is utilized to reduce the cost and time associated with testing. The size of the defects detected at the grid points must be determined and reported. The same acceptance criteria are applicable.
