Tube bending basics: How to bend tubing and metal pipe - The …
Feb 24, 2014 · The pressure die (also called a pressure slide) supports the outside radius during bending. The pressure die can be stationary; it can follow the workpiece, sliding on rollers at the same rate the workpiece is being drawn into the bend; or it can be “boosted,” pushed with hydraulics or (more common today) electrical servomotors, further minimizing wall thinning.
A guide to shielding gases for GMAW - The Fabricator
Jul 24, 2019 · Beyond quality issues, poor shielding gas performance can also drive up costs in the operation. A flow rate that is too high, for example, means you are wasting gas and spending more money on shielding gas than you need to.
ASME and AWS welding codes—Similarities and differences - The …
Aug 26, 2008 · The most commonly used codes for qualifying welders are the American Society of Mechanical Engineers (ASME) Section IX and American Welding Society (AWS) D1.1.
Bending Basics: The fundamentals of how to bend metal
Jan 2, 2014 · 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.
Identifying the right welding and cutting torch tips
Oct 9, 2003 · The tip of a welding or cutting torch is where the action is (see Figure 1).Welding tips usually produce positive pressure (higher than 1 pound per square inch [PSI]) and are used at equal pressures of acetylene and oxygen.
Bending Basics: The hows and whys of springback and springforward
Jul 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.
Guidelines for tungsten electrode and color types - The Fabricator
Mar 7, 2006 · Editor's note: To read an update regarding tungsten electrodes guidelines, click here. Tungsten is a rare metallic element used for manufacturing gas tungsten arc welding (GTAW) electrodes. The GTAW process relies on tungsten's hardness and high-temperature resistance to carry the welding current to the arc. Tungsten has the highest melting point of any metal, 3,410 degrees Celsius.
Aluminum TIG welding settings: What you need to know - The …
Jul 19, 2018 · Manufacturing products with aluminum can help extend part life, reduce weight, and deliver greater integrity in cold temperatures, making the material well-suited for applications such as truck and trailer manufacturing, cryogenic piping, and boat components.
Sheet metal bending calculation basics - The Fabricator
Nov 9, 2012 · The second flat-blank-development example adds the two dimensions (from edge to the apex), and subtracts a bend deduction. In this case, the calculations use a complementary angle for the OSSB, and the dimensions are called from the edge to the apex—again, as specified in Figure 4.. Outside Setback (OSSB)
