Welding Fillet Gauge

These are weld fillet gauges used to measure one side of a fillet at each time. I designed them to be put together with a m4 x 20 metric screw. Its just what I had handy, The four fillet sizes are 1" , 3/4", 1/2", 1/4". The way that you use these is by placing the bottom edge of the fillet gauge to the face of the base metal, and placing the tip of the fillet gauge to the face of the metal being welded together. Designed for Pieces of metal welded at a 90 degree angle only. Commonly used in the welding industry. Sorry for the weird file names, I didnt want to make the file name too long. Please feel free to comment and give suggestions. Save a couple bucks and don't buy these from a welding supply store!
