Critique my Welding

admin

I'm a wannab hobby welder (hence the screen name). I'm an office guy for my real job, but the oxy-acetylene welding is a great stress reliever at the end of the day. I've been practicing O/A welding for about six months now. Currently, I'm refining my skills with 24 gauge banding material. Controlling the heat and speed are...fun on this thin metal. I am working on mild steel up to about 1/4 inch thickness but no thicker than that.I'm interested in getting feedback on (the two photos) from you experts out there. These photos are 24 gauge banding material without using filler wire...except when I overheat the metal and blow thru. Then I use small strips of banding material as filler to close up the holes. Needless to say to my untrained hands, this is challenging.Feel free to critique as you see fit. Thanks in advance. Attached Images
Reply:I did a lot of O/A welding,,,, 15 years ago.I am thinking you have too much oxygen, or you are using a coat hanger for filler material and not using enough filler.Was the puddle popping and erupting moulin metal skyward?Most of the back side looks half way decent, so you have enough heat.After practice you welds can look like a tig weld where some used way too much heat.old Miller spectrum 625 Lincoln SP-135 T, CO2+0.025 wireMiller model 250 and WP-18V torchCraftsman 100amp AC/DC and WP-17V torchCentury 115-004 HF arc stabilizerHome made 4 transformer spot welderHome made alternator welder
