Plasma Cutter- Plasma cutting can be as aggressive and powerful or delicate as you want if setup properly. Oxy Acetylene Welding – This type of welding is the oldest method, but it’s still used by many today. In this method you are bending the metal over an edge or shape that is located under the metal. Hammer and Dolly– This is the most basic way to stretch metal. I got a 1994 dodge truck I want restore but is rusted out I am to get more it. Throatless shears waste no material when cutting. MIG welding creates sparks and requires more cleanup than the other methods above. MIG Welding- A MIG welder is the most common and probably the easiest form of welding to learn. i am a self taught fabricator so it is very important for me . Assembling: A process done by welding, binding with adhesives, and bending in the form of a crimped seam, Bending: A process done by hammering or via press brakes, Blanking: A process in which a part is cut out of the sheet metal, and the material around the part is discarded, Cutting: A process done by sawing, shearing, or chiseling with manual and power tools or torching with handheld plasma torches using computer numerical computer (CNC) cutters like lasers, Die cutting: A process that cuts metal pieces without the formation of chips or the use of burning or melting; also known as shearing, Fastening: A process using self-clinching tools like nuts, studs, spacers, access hardware, or cable tie mounts and hooks to provide torque resistance in applications where the sheet metal is too thin to be secured by other methods, Finishing: A process in which a completed metal project’s surface is altered to achieve a certain property, which includes improved appearance; adhesion or wettability; solderability; corrosion, tarnish chemical, or wear resistance; hardness; electrical conductivity; surface friction control; and blemish removal, Galvanizing: A process of applying a protective zinc coating to steel or iron to prevent rusting, Glazing: A process where two metals slide against each other to create a shiny, wear-protective layer of oxide, Hydroforming: A forming and fabricating process that uses a specialized type of die molding, which uses highly pressurized fluid to shape metals like steel, stainless steel, copper, aluminum, and brass, Metal punching: A process in which metal fabrication equipment punches holes, louvers, or a predetermined shape out of sheet metal, Milling: A process of using rotary cutters to remove material from a metal piece, advancing in a direction at an angle with the axis of a tool, Oxy acetylene welding: A process in which a tank of oxygen and acetylene combine with an adjustable torch to result in a precise, controlled flame used to heat metal, Roll forming: A constant bending process in which sheet metal, coil, bar, or strips of metal pass through rolls that form the metal, Shrinking: A process to remove small dents in which the direct damage isn’t severely stretched or torn and the hardness of the buckles isn’t severe, Spinning: A process by which a disc or tube of metal rotates at a high speed and forms into an axially symmetric part using a CNC lathe or by hand, Stamping: A high production process in which single or multiple punches, bends, and embossing perform simultaneously or in a progressive die, Stretching: A process that uses a hammer and dolly, a stretcher, or an English wheel to pull metal apart, Tucking: A method of shrinking metal by bunching it together through force using a crevice and spade hammer or a folding technique where the metal is bent at the edges with a homemade tucking fork, Tungsten inert gas (TIG) welding: A two-handed arc welding process that uses a non-consumable tungsten electrode to produce the weld. The lower wheel is then screwed up to pinch the metal between the two wheels and the metal is rolled back and forth slowly stretching the flat metal over the curved lower wheel. We offer a few different selections of angle grinders that are eager to be star players in your shop. There are many techniques and tools. Bending: A process done by hammering or via press brakes. Common custom metal fabrication processes are as follows: 1. In the case of complex, high-precision metal parts, chemical etching is the ideal option, delivering quality designs at an efficient pace. Drawing 4. This method is one that has been used to form some of the earliest most valuable sports cars. It is used for building aluminum cans and automotive panels. TIG welding is more precise than Oxy Acetylene welding and most modern fabricators prefer it. I am really impressed by the author explanation . Pulling Rivet. The type or amount of stretched metal or damage will determine how you shrink or smooth the area out. A List Of Common Sheet Metal Fabrication Techniques. It’s also the hardest weld, so it’s harder to grind and hammer flat. Eastwood offers a full line of TIG Welders and TIG Welding Supplies that will round out your sheet metal fabrication tools. The shrinker leaves minimal marring on the metal, most of which can be removed or smoothed out with a sanding disc or file. Hand Shears- Using hand shears or “aviation snips” is a manual, way to cut metal that’s necessary no matter how many large tools you have. Let the experts at Switzer help determine the best technique for your design project.
