Is any body has any idea about NDT (non destructive test for welding inspection?

Answer:

When stopping, down shift to low then stop using the rear and front brake. You can hold the bike steady with the front brake until you are ready to go. Then slowly engage the clutch and ease off the front brake at the same time. Launch when ready.
For magnetic materials eg carbon steel, Magnetic Particle Induction (MPI) is normally used - a spray containing magnetic particles is sprayed onto the weld, and a magnet is held close by. The magnetic particles will be pulled into any cracks and they will be visible. For non-magnetic materials eg stainless steel, usually the Dye Penetration (Dye Pen) method is used where a special red dye is sprayed onto the weld which will penetrate any cracks, and make them visible. X-raying of welds - If there are several, or even hundreds of welds, usually a sample is x-rayed (or 'bombed'). It's usually 10% of butt welds are bombed, and if any faults are found then the percentage is increased. Bombing is the best method, but takes far longer, more expensive, and means large areas of plant are inaccessible during the x-ray exposures. It's a matter of course that pipe-welds are normally hydro-tested also. That means the pipe-ends are blanked, the pipes are filled with water, any air is vented off, and the water pressure increased. The test pressure is usually 150% of maximum allowable working pressure for strength testing of welds, but this can vary widely depending on the client's specification Also it depends on the kind of industry you're talking of. An oilrig (where my experience is)would usually do the things I've stated above. For the nuclear industry, or aircraft industry, the specs may be more stringent (for example 100% bomb, every weld gets it). There's also various ultrasonic techniques (UT) that give an indication of how deep the weld is. There's probably more techniques, but these are the main ones by far.
well if you cannot get both feet on the ground, hold in the front brake, then lean so you have one foot firm on the ground, that should help, and if you dont care what you look like, pitch it sideways a little bit
Eddy current is used to detect cracks and ultrasonic can be used to detect depth.
The most effective way is by x-ray but for some cases ultrasonics, magnetic particle and dye penetratent are used.
