The Art And Science Of Bending Sheet Metal | Hackaday

May 18, 2016 · To think about bending a sheet of metal that has appreciable thickness, focus on an imaginary central sheet, the so-called neutral line or neutral axis, within the thickness. This neutral line behaves just like the thin sheet above, remaining undeformed during bending.

MIG Welder Settings for Various Metal Thickness's

Metal Thickness & Amperage Settings: When welding mild steel, a good rule of thumb is to set the amperage level at 1 amp for every 0.001" of thickness. So if you are welding 12 gauge mild steel with a thickness of 0.100", you would set the machine at 100 amps.

A rundown on rolling machines - thefabricator

Oct 04, 2010 · Some machines have extended roll shafts that protrude through the machine frame. Section or pipe dies can be fitted on these stub shafts, but it is not practical to roll angle iron on a plate roll. Angle tends to twist when rolled, and plate rolls do not have outboard, adjustable, lateral material guides to prevent this twist.

Sheet Metal Bending - thelibraryofmanufacturing

As the sheet metal is bent, the force needed will change. Usually it is important to determine the maximum necessary bending force, to access machine capacity requirements. The important factors influencing the mechanics of bending are material, sheet thickness, width over which bend occurs, radius of bend, bend angle, machinery, tooling and specific metal bending process.

Measuring Metal Thickness Through Paint - Olympus IMS

A conventional ultrasonic gage that measures the total thickness of painted metal will erroneously measure the paint layer at the velocity of steel, meaning that the paint will appear to be at least 2.35 times thicker (the ratio of the two sound velocities) than it actually is.

Amperage chart for different metals and their thickness

Dec 19, 2015 · I looked in the stickies, but didn't see any charts for how much amperage to use when using a TIG welder. I'm in the process of making a welding table and I've burned a few holes on the 1 1/2" 0.95 square iron I'm using for the frame of the table. I had the setting to 125 amps, lowered to 115 and made a difference. Is there a chart the specifies how much amps to use on which metals with ...
