hello my my name is zach and im new to black smithing/ bladesmithing. I have build a forge at my metal fabrication buisness, it is a freon tank with a 6 inch sonatube center with castable refractory for insulation. it seams to be working ok but im having some trouble with my forge welds holding, ive been trying my hand at some damascus blades made with 1095 5160 and 15n20. my problem is that im having delamination seams to be only around the areas with 15n20. Im thinking not enough heat.... my forge has 2 forced air burners, instead of a blower ive been using my air compressor, with valves to regulate, im thinking that its still to much pressure and not enough volume. ive been runing about 10 psi, although ive tried up to 25. ive messed with the air flow from really lean to running it really rich. I understand that i should have some dragons breath or small flames coming out the front door and i should have it runnning a little ritch to avoid an oxygen ritch atmosphere. now i do have some water in my air lines, is this possible that the water in the lines is somehow cooling my burn..... any ideas would be greatly apreciated, I have attached some pics of my forge.
