Hello. So the title pretty much explains it all here. Support gets XP for welding doors, and being the "welding guy" of the team it should also get XP for welding objectives. Support also has one of the slowest XP gains of all the perks when compared to things like "XP on headshots", "XP on crawler kills", etc. Welding doors is anything but a majot part of the game, and this change would both make sense from a consistency perspective and a balance one.
