METALWORKING HANDOUT Sheet Metal Welding Wrought Iron Work Casting Metal Material nFerrous – a metal that contains ____________ nExamples – Steel, Cast-iron, nNonferrous – a metal that has no iron in it. nExamples – Aluminum, Brass, Copper, nAlloy – is a ______________ of two or more metals.
Methods of Shaping or Forming Metal
Steel Bar Stock nBar Stock can be cut to length with a _________ saw, band saw, or cut-off saw. nBar Stock comes in a variety of shapes. nThree common shapes are round, ______________ and flat (rectangle).
CAM nComputer Aided Manufacturing nMachinery run with the help of a _________________
Sheet Metal nStandard Sheet Metal comes basically two ways: nNon coated steel nThis type of sheet metal can be _______________. nGalvanized steel nThis type of sheet metal has a coating to help it from___________. nSheet metal is used for office furniture, duct work, cars, containers, etc.
Sheet Metal Sizing nSheet metal comes in a roll or large sheet nThe thickness of sheet metal is determined with a gauge number. nThe ____________ the number gauge the thinner the metal. nExample – 28 gauge is thinner than 24 gauge
Cutting Sheet Metal nCutting by hand nStraight snip nAviation snip nCutting by machine nShear
Sheet Metal Layout nLines are drawn on sheet metal with a scriber that scratches a line on the metal. Bending Sheet Metal nBox and Pan Brake is usually used in our shop to bend the sheet metal into the desired shape. nHems are usually bent onto the edges of sheet metal where it is going to be exposed, to create a ___________ edge and to strengthen the edge. nTabs are placed on the corners or sides of sheet metal to help __________ the sheet metal together.
Fastening Sheet Metal
nRivets nSolid rivet nPop rivet nSize is given in length and ______________ nMaterial is usually _____________ or aluminum.
Welding nAcetylene (Gas) nThis type of welding uses a _______ and oxygen mixture to create a flame that melts the metal together to fuse it into one. nArc (MIG) nMetal Inert Gas nMIG welding uses an electrical charge at the end of a wire that is fed through a gun, when this wire is very close to the metal it creates an _________ that is hot enough to ____________ the metal.
Acetylene (Gas) Welding nRed or Brown hose and tank represent _____________ nGreen hose and tank represent _______________ nThe tanks should be opened a ___________ a turn. nThe gas valve on the torch should be opened first nThe torch should be lit with a flint sparker nThe torch should be adjusted to a small ____________ cone in the center of the flame. nWelding rod is added to the weld for _______________
Arc (MIG) Welding nArc welding uses ________________ to create a arc that melts the metal and a gas that keeps the weld area clean. nA wire is fed through a gun to create an arc and _________ metal to the weld. nThe metal must be ______________ before welding. nDark lens and a helmet must be used to protect your eyes and skin from the bright light that is created from the arc.
Brazing nBrazing is done with a gas torch and a special __________ rod that is covered with a flux to keep the area clean. nMetal that is brazed is heated red hot, but not melted, then the brass rod is added to work like an adhesive to hold the metal pieces together.
Spot Welding nSpot welding uses an electrical current that travels through copper rods touching both sides of the metal being fastened together at an exact point. At that point it ____________ the metal and welds it together.
WELDING SAFETY
nAlways ______________ yourself and the welding area for work nNever weld over grease, oil, water or other wet surfaces. nAlways use tongs or pliers for handling ________ metal, not the welding gloves. Assume all metal is hot until you decide otherwise. nAlways have the area well ventilated. nKeep the area free of scrap metal and other obstructions which can cause serious accidents.
Gas Welding Safety (Oxyacetylene) nProperly prepare yourself and the welding area for work. nTurn on the exhaust __________. nUse shaded glasses or goggles to _____________ your eyes. nCheck torch for valves before opening tanks. Make sure valves are closed. nNever exceed ______ lbs. On oxygen or ________ lbs on acetylene regulators. nHandle torch with extra care when workers are around. nAlways turn off the torch when you have ________________ a weld. nReturn welding equipment and area to proper order upon completion. nCoil up hoses and remove hot metal. nMake sure tanks valves are _____________. nTurn off exhaust fan.
Arc Welding Safety nAlways have your body well covered with protective clothing before starting to weld. nUse a helmet with ___________ lenses to protect your eyes. nWear proper gloves. nClamp the ______________ wire on the metal or table that you are going to weld. This must be a good clean spot, free of paint and other surface finishes that might cause a poor ground. nTurn on the _________ valve, a half a turn. nCheck the machine for proper settings before turning it on. nAs you prepare to start the weld make sure you announce to anyone in the area to ____________ their ____________. nReturn welding equipment and area to proper order upon completion. nMake sure the tank is closed and the machine is turned off. nTurn off exhaust fan.
Cutting Holes & Threads nLocate the center point of the hole with a center _____________. nUse a hand drill or drill press to drill the hole. nCut holes with a ___________ drill bit. nTwist drill bits are sized by: nFractions & decimals nNumbers nLetters nThreads are cut with a: n___________ – for external threads. (Bolt or screw) n___________ – for internal threads. (Nut) nBefore cutting the internal threads a pilot hole must be made according to the size of the ___________ diameter of the thread.
