After practicing running stick welding beads on a 3/16 steel plate I wanted to cut it up to practice T joints and but joints, etc.
I was trying to cut the plate with a Bauer portable band saw. The saw is mounted in a Swag table. The depth of cut is limited so I cut half the way through and planned to turn the piece around complete the cut. However, I couldn't back the saw blade out of the completed cut. The entry cut closed up on me.

I'm assuming the problem is built-in stress in the plate that caused the material to move and close up after I started the cut.

How do I relieve the stress before I try to cut it?

If it’s only 3/16” plate you want to cut, you could do that with an angle grinder/zip disc combo.

Unless you have your own heat treating oven to get the part to annealing temperature to relieve the internal stress, you'll have to work around it when doing your cuts. A thin 045 cutting disc on an angle grinder will work just fine.

Or like any material that pinches on the cut whether wood or metal simply drive a small wedge / chisel / screwdriver into the end of the cut once in past the blade width - it's a common problem cutting with carbide circular saws ( like the Evolution ) as the blades have very little side clearance.
