Ab -7.62 suppresor

Hey I picked up my AB WORTHHOG 7.62 this afternoon I finished all paperwork, when I arrived at my residence I started to inspect my warthog I seen 3 deep weld pockets deep into can. Not sure if this okay or will it cause holes over time possibly due to pressures. Never seen this before this is currently my 4th can this is the first time I see this. The other welds are nice and and round.
