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.
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.
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)
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.
Understanding GMAW transfer modes - The Fabricator
Dec 14, 2008 · The gas metal arc welding (GMAW) process uses four basic modes to transfer metal from the electrode to the workpiece. Each mode of transfer depends on the welding process, the welding power supply, and the consumable, and each has its own distinct characteristics and applications.
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.
The truth about pipeline welding and pipeline welder salary
Mar 25, 2020 · Pipeline Welders' Career. TW: Why did you choose a career as a pipeline welder? KA: I would love to tell you I became a pipeline welder to see the countryside and the scenery, but the truth of the matter is, it was because of the money. The amount of income you can generate working pipeline far surpasses what you can make working close to home or in a small shop.
Welding fumes, their health risks and hazards - The Fabricator
Mar 11, 2004 · In 2003 NIOSH published a comprehensive review of scientific literature on health effects associated with welding. The article, "Health Effects of Welding,"1 noted that past investigations have found bronchitis, airway irritation, and other respiratory illnesses in large numbers of welders.
Gas tungsten arc welding fundamentals: Understanding GTAW
Feb 19, 2001 · 2. Thoriated tungstenis the most common type of tungsten electrode for use on carbon and stainless steel.It can be purchased with 1 or 2 percent thorium. The thoriated tungsten starts readily and maintains a stable arc. It has a greater resistance to contamination and will maintain a sharp point and will not break down as readily as pure tungsten.
