Q:- The similarities between BS EN22553 and AWS A2.4in deciding welding symbols are

1. Both have the same rule for depicting weld at round
2. Both have the same rule for depicting other side
3. Both have the same rule for depicting sequence of operations
4. Both have the same method for depicting welding process

Q:- Why is it essential to clean the surrounding parent metal adjacent to the weld metal made by MMA(SMAW)which is to be ultrasonically tested?

1. Sound waves will not travel though paint 
2. Remove any rust 
3. The spatter will impede the contact of the probe and the parent material surface 
4. Spatter will reflect the back will echo signal and give spurious indications 

Q:- While inspecting a weld on a 100mm thick high carbon steel plate with tolerance of +5mm you find the weld is visual acceptable, however the parent material has several arc strikes present adjusted the weld approximately 3mm drop deep, what course of action would you take?

1. None I am only inspecting the weld
2. Recommended that the area be dressed smooth
3. Recommended that the area be dressed smooth followed by MPI
4. High carbon steel is net susceptible to cracking so I would weld over the arc strikes then blend them

Q:- When reviewing a radiograph of a weld made by the MAG(GSMAW)process, you notice a very bright white inclusion in the weld, which of the following best describes this indication?

1. Tungsten inclusion
2. Spatter on the cap
3. Copper inclusion
4. It is most likely to be a film mark
