Oxygen And Acetylene Regulators

The gases stored in the gas cylinders used for oxy-acetylene welding are originally at very high pressure, and cannot be directly used as such. Here, the oxygen and acetylene regulators play an important role in reducing this pressure to a working pressure. These regulators enable maintaining a constant desired pressure at the point of delivery, … Read more

Stationary Oxyacetylene Welding Equipment

Stationary oxyacetylene welding equipment is installed where welding operations are conducted in a fixed location. Oxygen and acetylene are provided in the welding area as outlined below. Oxygen. Oxygen is obtained from a number of cylinders manifolded and equipped with a master regulator. The regulator and manifold control the pressure and the flow together (fig. 5-1). The oxygen is … Read more

MIG Welding Equipment | Gas Metal Arc Welding (GMAW)

MIG Welding Equipment, Gas Metal Arc Welding (GMAW). GMAW is most commonly referred to as “MIG” welding, and the following text will use “MIG” or “MIG welding” when referring to GMAW. MIG welding is a process in which a consumable, bare wire electrode is fed into a weld at a controlled rate of speed, while a blanket … Read more

OxyFuel Welding Sheet Metal

 Welding Sheet Metal. (1) For welding purposes, the term “sheet metal” is restricted to thicknesses of metals up to and including 1/8 in. (3.2 mm). (2) Welds in sheet metal up to 1/16 in. (1.6 mm) thick can be made satisfactorily by flanging the edges at the joint. The flanges must be at least equal … Read more

Electron Beam Welding (EBW)

a. General. (1) Electron beam welding (EBW) is a welding process that produces coalescence of metals with heat from a concentrated beam of high-velocity electrons striking the surfaces to be joined. Heat is generated in the workpiece as it is bombarded by a dense stream of high-velocity electrons. Virtually all of the kinetic energy, or … Read more

MIG Welding Procedures

MIG welding procedures are similar to those for other arc welding processes. Adequate fixturing and clamping of the work are required with adequate accessibility for the welding gun. Fixturing must hold the work rigid to minimize distortion from welding. It should be designed for easy loading and unloading. A good connection of the work lead (ground) … Read more

Resistance Welding Aluminum

Resistance Welding Aluminum. The resistance welding processes (spot, seam, and flash welding) are important in fabricating aluminum alloys. These processes are especially useful in joining the high-strength heat-treatable alloys, which are difficult to join by fusion welding but can be joined by the resistance welding process with practically no loss in strength. The natural oxide … Read more

Electron Beam Welding Aluminum

Electron beam welding is a fusion joining process in which the workpiece is bombarded with a dense stream of high-velocity electrons, and virtually all of the kinetic energy of the electrons is transformed into heat upon impact. Electron beam welding usually takes place in an evacuated chamber. The chamber size is the limiting factor on … Read more

TIG welding versus MIG welding

TIG welding versus MIG welding machines MIG welding machines can make quick work of those around the house projects.  With a basic configuration, you have your MIG welding machine set up with “gasless” filler material commonly known as “Flux Core“.  It welds ok, but you find that if you want “clean” results you need a bottle of Argon/Co2 75/25% … Read more

TIG Welding Process

TIG Welding Process requires careful keeping in mind of several things such as torch angle, filler metal angle, grinding the tungsten electrode for preparing it for welding. This article covers some of these and includes some tips for tig welding stainless steel at the end. Things To Keep In Mind When TIG Welding Position TIG … Read more
