2. Oxy-fuel welding and cutting - Wikipedia

   en.wikipedia.org/wiki/Oxy-fuel_welding_and_cutting

   The same equipment can be used for oxyacetylene blowtorches and welding torches, by exchanging the part of the torch in front of the torch valves. For a basic oxy-acetylene rig, the cutting speed in light steel section will usually be nearly twice as fast as a petrol -driven cut-off grinder.

4. Metal fabrication - Wikipedia

   en.wikipedia.org/wiki/Metal_fabrication

   Workers welding in parking garage. Welding is the main focus of steel fabrication. [8] Formed and machined parts are assembled and tack-welded in place, then rechecked for accuracy. If multiple weldments have been ordered, a fixture may be used to locate parts for welding. A welder then finishes the work according to engineering drawings (for ...

5. Arc welding - Wikipedia

   en.wikipedia.org/wiki/Arc_welding

   It is a type of welding that uses a welding power supply to create an electric arc between a metal stick ("electrode") and the base material to melt the metals at the point of contact. Arc welding power supplies can deliver either direct (DC) or alternating (AC) current to the work, while consumable or non-consumable electrodes are used.

6. Shielded metal arc welding - Wikipedia

   en.wikipedia.org/wiki/Shielded_metal_arc_welding

   Shielded metal arc welding is one of the world's most popular welding processes, accounting for over half of all welding in some countries. Because of its versatility and simplicity, it is particularly dominant in the maintenance and repair industry, and is heavily used in the construction of steel structures and in industrial fabrication.

7. Welding - Wikipedia

   en.wikipedia.org/wiki/Welding

   All arc welding processes use a welding power supply to create and maintain an electric arc between an electrode and the base material to melt metals at the welding point. They can use alternating current (AC) or direct current (DC). For DC welding, the electrode can be connected to the machine's positive terminal (DCEP) or negative terminal ...
