Welding Sheet Metal Flexible Manufacturing

Sheet Metal There are many types of sheet metals manufactured for various applications. The sheet metal may be developed to bend, stretch, or to resist corrosion. The application will determine what alloys are added to the steel when making it.

History of Sheet Metal Sheet metal is formed when a hot steel ingot is squeezed between a series of rollers. The rollers apply pressure and compress the metal into a long, thin sheet.

Rolling Mill Animation

Hot Rolled vs. Cold Rolled Formed while hot Not uniform in thickness Surface can be scaly Less expensive Cold Rolled Formed when cold Uniform in thickness Surface is smooth Costs more than hot rolled Surface can be grained or textured

Sheet Stock in Flexible Manufacturing Sheet stock used in a lab will be different gauges of steel, and it could include materials such as copper, aluminum, and brass.

Welding Sheet Metal Oxy-fuel Process Welding sheet metal is achieved by heating the edges of the metal and adding a filler rod into the weld pool.

Welding Sheet Metal The torch tip selected should provide the right amount of heat to melt the metal and rod. If the tip has a large opening, the metal will heat too fast, causing the puddle to be too hard to control, which causes a poor weld.

Welding Sheet Metal The weld joint should be tacked in a few places before welding, to keep the joint from warping and twisting.

Welding Coated Metal Zinc and other coated metals should be welded with great caution. Weld only in a well-ventilated area.

Shielded Metal Arc Welding on Sheet Metal Welding on thin sheet metals requires a smaller diameter electrode and less amperage. When welding 1/16” thick sheets together, the electrode used will be a 1/16” diameter rod with the amperage set at 20-40 amps. The amperage used should not melt the metal too fast; this will cause burn through. Overheating of the weld makes it hard to control the weld pool and causes a poor weld.

Shielded Metal Arc Welding on Sheet Metal The welder will need to tack-weld the joint in different places to keep the welded metal even. Overheating the metal causes it to wrap, twist, or spread apart.

Gas Metal Arc Welding on Sheet Metal Gas metal arc-welding uses a thin wire for the electrode. The electrode is fed through the machine and out of a gun. The gun also has argon gas piped to it. The gas envelopes the arc and shields the molten puddle from the atmosphere.

Gas Metal Arc Welding on Sheet Metal The small diameter of the wire electrode makes it easier to weld sheet metal. The amperage can be set lower to keep from burning through the metal edges. The operator can set the feed rate for the wire electrode, controlling the arc more easily.

Gas Metal Arc Welding on Sheet Metal Used on production lines Used in welding and auto body repair shops

Welding Electrodes Common Types of Electrodes Different types of welding have different styles of electrodes. The electrode provides the path for the current to flow to the metal to be welded.

Welding Electrodes E6013 Common Types of Electrodes Shielded metal-arc welding (SMAW) or “stick welding” uses a metal rod coated with a flux. They have a number system that describes the rods, tensile strength, coating, welding current, and direction. E6013

Welding Electrodes Common Types of Electrodes Gas metal arc-welding (GMAW) or “MIG welding” uses a thin wire loaded into the machine’s feeder. The wire is sized by diameter.

Welding Electrodes Common Types of Electrodes Gas Tungsten Arc Welding(GTAW) or “TIG welding” uses a tungsten rod as the electrode. Oxygen Acetylene (OAW) uses a metal filler rod in the welding process.
