Most of the light gauge sheet metal work will require the use of .023- or .24- inch while if you have a sheet metal . It’s easier for me to tack in place with the Mig, then gas weld. I have a 3-1 machine that has Tig, I’m just not good enough to use it on light gauge metal. With a O/A I can come “in and out” and control things. My 3-1 doesn’t have a foot pedal so I . Gas weld with NO FILLER rod, a fusion weld. A gas weld is also easier to correct any warpage issues because the welded joint is softer then both the TIG and MIG, with MIG being the hardest to correct. If you can weld a seem shut and NOT stop, do one continuous weld your shrinkage will be far less.
Advantages of Welding Without Filler Metal. Here are some advantage of working without filler metal: Low or zero cost per weld. Traditional welding processes generally require the use of filler metal, which can add up to a significant cost. Welding without filler metal, however, has no additional cost because the process itself creates a weld .
Sometimes, sheet metal welding welders may use separate filler metal in TIG welding to reinforce the seams. However, it is usually suitable for non-ferrous metals like aluminum, copper, titanium, etc., especially in the aerospace industries, among . I do all my sheet metal welding with a Gas MIG set up. I haven't ever tried O/A or TIG. One thing i did find was a huge help was changing the wire size. I was using 0.8mm wire as i was doing alot of chassis welding as well. I then baught a spool of 0.6mm for sheet metal work and the difference is great. Gas welding is an art, and one worth pursuing just for the pleasure of working with metal. But the best reason to gas weld is it makes you a much better welder with the other tools. In my opinion no one should be allowed to purchase a MIG until they can do a passable job of butt welding 20ga with a torch. A gas welding technique question: Most textbooks tell you to butt thin sheetmetal together then tack and weld. When I was taught gas welding at a coommunity college, the instructor insisted that all metal 1/8" or less should have a gap of the metal thickness between them. Then you tack and weld. He claimed much reduced distortion as a result.
4. Metal Fabrication and Repair. Gas welding is widely utilized in metal fabrication and repair processes, providing flexibility and efficiency in joining metal components. Key applications include: Sheet Metal Fabrication: Gas welding is employed in the fabrication of sheet metal components, such as cabinets, enclosures, and structural parts. It will ,however you will see a sort of "muddy" puddle with the gas torch because the extra de-oxidizers added for TIG welding will float on the surface of the puddle. The proper rod to use is an R45 designation, a mild steel fusion gas welding rod that will give a nice clean puddle with a neutral flame and a good strong weld. How to Weld Brass: Welding brass with oxy-acetylene. Gas welding or oxy-acetylene welding of brass if required is carried out using a Cu 5180 (CuSn6P) type rod. However, gas welding or brass is not recommended as during gas welding due to heat, zinc will vaporize. This zinc vaporization will produce a lot of fumes & result in porosity.
