: hello folks!! Does the 'plasma transferred arc' (PTA) process qualify to be a direct part of surface engineering since it is more a welding kind of process? How do you acutally differentiate welding processes from surface engineering (coating processes)? Welding also involves some surfacing techniques. Im dying to find out.
Your queston would have been more appropriate as follows
Is PTA a thermal spray process?
PTA using powder consumable is considered as a thermal spray process.
surface engineering processes include welding processes.To get a clear picture you can read my book on 'advanced thermally assisted surface engineering processes',kluwer academic publishers, MA,(go to website of the title for details).
