Welding Tips and Tricks

this is a project that's been taking up a major share of shop time for the last couple weeks. to prevent disturbed inmates from harming themselves we've made a cell door out of 1 inch lexan with a steel frame that has the mounting brackets welded to it also there is a feeding/handcuff hatch made from the same see through material.

Pritty cool you get to build something so simple with such a big impact at the same time. Did you guys design the door aswell?
