I have been pricing up 8x4 sheets of steel and can't really afford anything thicker than 6 mm plate for my welding table would this be OK or a total waste...
My 740 x 1400 mm bench is two layers of 3/8" (about 9.5 mm so total 19 mm) plate laminated and plug welded together - why - because that's what I had at the timeIt's extremely solid and allows me to clamp things down or bash them about without the table being damaged - been using it for 15 years and it's as good as new. Big heavy lump to move about though, so it's on locking castors.
