Hi, how do I unite surfaces in an igs imported dumb solid in UG NX, I need to unite to form a single surface to enable robot programming. Pls help..

have you looked into sew and unsew? This would really depend on how clean your IGS import geometry is coming into NX.

in the surface ribbon, there is a sew surface tool. (it may be hidden and you will need to turn it on in the ribbon)

select this tool and select one of the surfaces.
select all the other surfaces that you want united.
hit the preview option to see if/where you have errors (you will most likely have errors)
if you are certain that you are not missing a sliver and it still refuses to sew, you can change the tolerance to a higher value and hit preview again. increase the tolerance in small increments, too high of a number can cause issues too.
once preview is clean, hit ok

You may need to sew a little bit at a time. Often, big, grand, all-at-once sew operations can fail.

Honesty may be the best policy, but insanity is a better defense.

Also check this in the import options

Would it be possible to avoid using the IGES format ?
The IGES standard is an old and outdated file format.
The last (!) published standard is 5.3 which was published 1996. 25 years ago.
If the systems you work with can use STEP / JT / Parasolid instead you might not see these issues at all.
