Oxy-acetylene torches can easily cut through ferrous materials in excess of 200 mm (7.9 in). Oxygen lances are used in scrapping operations and cut sections thicker than 200 mm. Cut-off grinders are useless for these kinds of application. Robotic oxy-fuel cutters sometimes use a high-speed divergent nozzle.
In brazing copper, a reducing atmosphere (or even a reducing flame) may react with the oxygen residues in the metal, which are present as cuprous oxide inclusions, and cause hydrogen embrittlement. The hydrogen present in the flame or atmosphere at high temperature reacts with the oxide, yielding metallic copper and water vapour, steam.
Genuine MAPP gas can be used in combination with oxygen for heating, soldering, brazing and even welding because of its high flame temperature of 2925 °C (5300 °F) in oxygen. Although acetylene has a higher flame temperature (3160 °C, 5720 °F), MAPP has the advantage that it requires neither dilution nor special container fillers during ...

Spray transfer GMAW. Gas metal arc welding (GMAW), sometimes referred to by its subtypes metal inert gas (MIG) and metal active gas (MAG) is a welding process in which an electric arc forms between a consumable MIG wire electrode and the workpiece metal(s), which heats the workpiece metal(s), causing them to fuse (melt and join).
The Brown Hotel: The Hot Brown. Louisville, Kentucky The hot brown is an open-faced sandwich with a layer of toast, roasted turkey, bacon, and tomato topped with creamy mornay sauce and broiled.
4. Kalen DeBoer (Alabama) DeBoer misfired in his first season replacing Saban. No sugar coating it. He certainly hasn’t, acknowledging he failed to meet expectations.
Think of whether there were any goals you set out to accomplish. If you did, great—onto the next goal. If you didn’t, head into your first week post-deload exercising at a lower intensity ...
