Haz area to ensure the safe must be made several mechanical tests such as Hardness, Impact test. Engineering calculations of how much value or impact hardness test is described the service of joint this back in the day, and are assumed safe in operation.

I think the problem is not a problem that is too special and it is usual in the world of manufacturing. It is important to me how designers can get engineering welding mechanical test results in accordance with that expected in the client spec. Brain especial welding parameters of the right will get optimum value from the planning pWPS will be made.

Distortion problem is also commonplace, the heated material occurs at the time of expansion and cooling shrinkage occurs. Distortion can be avoided by making the right design and right before the welding joint preperation, such as design, design the type of welding process, HI design, design welding sequences, the use of strong back, etc.. if we can design welding distortion preventive Maa will be safe from its distortion.

In fact we can see that great distortion that occurs when the welding process to complete the NDE technique, known as ESPI (Electronic Speckle Pattern Interferometry). Father can see in real-time display of displacement that occurred in 3 dimensions
