I know Ivan has a reputation for rough welding but the post-war stuff was done is a bit less of a panic than Tankograd in 1942 and the welds on the glacis look a bit rougher than I've personally seen on a T-55; both where the glacis meets the chin and where the roller mounts are attached. Fortunately there are plenty of T-55 photos around to examine so you might want to compare a few and then either ignore me (always a rational response) or clean them up a little.
Do I see a mould line on the cable housing that runs up the turret roof? Might be the lighting.
