We may have to check the actual extent/ condition of damage in welds to evaluate the repairing possibilities.

In principle Possible. U can use pulsed TIG welding process with  same type
filler wire and  a lower size.

But u have not mentioned the type of defect in the weld for better guidance.

Welding done with seam welding process  and found lack of fusion ,visual is rejected. Now the client is insist us too do repair welding and the joint should be full penetration weld according to ASME B31.3 seam welding.
Since it is 3mm thick material we need to do high travel speed welding , can we use GMAW -STT  process?

Indication shows as gap between cladding materials due to incomplete fusion or penetration
