Nondestructive testing (NDT) of welding joints are increasingly asked for on the construction market. This is due primarily to the fact that welding joints are suffered the most from defects of any kind as well as welding defects lead to loss of physical properties both materials and construction. NDT allows testing of welding joints on the operational suitability preserving the joints integrity and suitability of construction as well.
