Aluminum TIG welding settings: What you need to know - The …
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.
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 ...
K-factors, Y-factors, and press brake bending precision - The …
WEBMar 7, 2018 · Calculating K-factors. The K-factor is defined mathematically as t/Mt, where t is the neutral axis location and Mt is the material thickness. Because of the specific properties of any given metal, there is no easy way to calculate that value perfectly, hence the chart in Figure 2.
Bending Basics: The hows and whys of springback and springforward
WEBJul 9, 2014 · Figure 3 Coining, bottom bending, and air forming affect stressstrain properties differently. The curved line in the air forming zone shows how springback changes at different bend angles. In bottoming and coining, bending methods that usually produce 90-degree bend angles, the line curves to the right of the vertical axis, showing how the metal springs forward to conform to the die angle.
Sheet metal bending calculation basics - The Fabricator
WEBNov 9, 2012 · Sheet Metal Bending Calculation. Bend Allowance (BA) BA = [ (0.017453 × Inside radius) + (0.0078 × Material thickness)] × Bend angle, which is always complementary. The length of the neutral axis is calculated as a bend allowance, taken at 50 percent of the material thickness.

WEBJun 26, 2003 · A Closer Look. Remember there are three basic crystalline structures favored by metals: body-centered cubic (BCC), face-centered cubic (FCC), and hexagonal close packed (HCP). Pure iron is one metal that changes from one of these crystalline structures to another while remaining solid. It's BCC at temperatures up to 1,670 degrees F.
Die basics 101 starts with eight basic components - The Fabricator
WEBAug 8, 2006 · A stamping die is a special, one-of-a-kind precision tool that cuts and forms sheet metal into a desired shape or profile. Most dies are constructed of several basic components, including die plates, shoes, die sets, guide pins, bushings, heel blocks, heel plates, screws, dowels, and keys. Dies also need stripper, pressure, and drawing pads, as well as the devices used to secure them—spools ...
The truth about pipeline welding and pipeline welder salary
WEBMar 25, 2020 · Photos courtesy of Keith Armentrout, Burnet, Texas. On average, a pipeline welder can make between $36 and $52 an hour on arm pay, anywhere from $15 to $25 an hour for the truck pay, and then somewhere between $100 and $150 for the per diem. With all that, let's just say for an example, on a 60-hour workweek a …
