Gas tungsten arc welding fundamentals: Understanding GTAW
WEBFeb 19, 2001 · Article. Arc Welding. Gas tungsten arc welding (GTAW) is an electric arc welding process that produces an arc between a nonconsumable electrode and the work to be welded. The weld is shielded from the atmosphere by a shielding gas that forms an envelope around the weld area (see Figure 1). Figure 1:
Bending Basics: The fundamentals of how to bend metal
WEBJan 2, 2014 · Bending and Forming. Figure 1: A plate’s grains run parallel to the rolling direction. While sheet metal gauges run from 0.005 to 0.249 inch thick, aluminum and steel plate thicknesses start at 0.250 in. and go all the way up to 13 in. or even more. Likewise, plate steel varies in strengths from mild varieties to some very high-strength ...

WEBJul 19, 2018 · The rule of thumb for aluminum GTAW is to use 1 amp for every thousandth (0.001) of material thickness. In other words, welding a base material that is 1⁄8 in. (0.125) thick would require about 125 amps. When the base material is more than ¼ in. thick, the rule of thumb begins to deviate, and not as much amperage is needed.
6 steps to successful brazing - The Fabricator
WEBMar 7, 2006 · Step 1: Ensure good fit and proper clearances. Brazing uses capillary action to distribute molten filler metal between the surfaces of the base metals. So when you're brazing, maintain a clearance between the base metals to allow capillary action to work most effectively. In almost all cases, this means a close clearance.
