State six weld testing types that should be performed in accordance with these standards.

1. Visual inspection: This involves examining the weld for any visible defects such as cracks, porosity, or incomplete fusion.

2. Radiographic testing: This method uses X-rays or gamma rays to inspect the internal structure of the weld for defects that may not be visible to the naked eye.

3. Ultrasonic testing: This technique uses high-frequency sound waves to detect defects in the weld by measuring the time it takes for the sound waves to travel through the material.

4. Magnetic particle testing: This method involves applying a magnetic field to the weld and then applying magnetic particles to the surface. Any defects in the weld will cause the particles to gather in specific areas, making them visible to the inspector.

5. Liquid penetrant testing: This method involves applying a liquid dye or fluorescent penetrant to the surface of the weld. The penetrant seeps into any surface defects, which are then made visible under ultraviolet light.

6. Tensile testing: This involves subjecting the weld to a controlled tensile force to determine its strength and ductility. This test helps ensure that the weld will perform as expected under load.
