HNITSUJ:Has onyone welded d-rings to the side-bottom edges of their plate? I saw it and thought it would be great for backup reel, bug bag, john line etc. Keep things out of the way but within reach
ChrisA:Very hard to weld stainless in a way that will not rust. The heat does something to the metal and it becomes less rust resistent. Yes it can be done but it require a very skilled welder who knows about the exact types of alloys involved.
I've got a boat in saltwater and I'll tall you. Anytime a stainless fitting fails it is always the weld that goes.
Night Diver:I agree and although I am not a metalurgist (nor do I play one on TV) I recall from my younger mechanical days that we were never allowed to weld to the flanges of tempered, bent steel because of the increased danger of cracking the steel. So it was the belief at that time (and remains my belief) that welding to the edges creates the chance of not just the weld itself breaking (even though some will swear up and down that a weld itself never breaks, it does) but also the chance of the plate forming a crack from that point. Just seems like a risk for little benefit.
cool_hardware52:The 300 series SS used for plates cannot be heat treated, and therefore would not be either hardened or tempered. Welding should have very little effect on the properties.
Passivation is a good idea. If you lack the heated nitric acid bath, glass bead blasting will provide a measure of mechanical passivation.
Welding to heat treated steel, such as the the frame rails on a truck, will casue localized annealing. This localized softening can lead to cracking.
Welds shrink, and depending on the joint design, this shrinkage can induce very high local stresses. Peening the weld, or reheating the entire area post welding can relieve the stress. Can welds crack? You betcha! Is it a concern in this lightly loaded application? I doubt it.

mike_s:Don't weld the D-ring directly to the plate. It will make the ring "rigid" and non-moveable.
