Who should select the specific welds for NDT, to cover the 10% contractual percentage required by the specification code

Who determines what the correct preparation (root gap, root face, included angle) should be?

In a transverse weld tensile test, if the break was in the weld material, the sample would be

In a welder qualification testing of 45 mm plates, why are side bends used instead of root and face bends

When examining a completed bend test, the angle of the bend was found to be 185°. The testing specification calls for the sample to have been formed through 180°

In a cross joint tensile test, the following observations were made; specimen width: 20mm, material thickness: 20mm, max load 180KN, break position: parent plate. What is the UTS?

Charpy impact test showing rough torn surface after the completed test, this would indicate which type of failure

A butt weld has been made by MMA in a 50 thick impact tested steel plate. The welding electrode used was a basic type 5mm diameter, the measured running parameters for one run was

What is a typical ARC voltage setting when welding with TIG (GTAW) process in AC?

When MMA welding what will be the effect on the weld if the power source was changed from AC to DC -ve?

When using multiple SAW arc systems (twin wires etc.), the arc often has different polarities or use all AC rather than DC polarity. This is to

How is preheat for tack welds during assembly and fit up determined?
