Arc welding power supplies can deliver either direct (DC) or alternating (AC) current to the work, while consumable or non-consumable electrodes are used. The welding area is usually protected by some type of shielding gas (e.g. an inert gas), vapor, or slag. Arc welding processes may be manual, semi-automatic, or fully automated.
Oxygas welding station (keep cylinders and hoses away from the flame) Gas welding/cutting goggles and safety helmet. Oxyacetylene welding/cutting is generally considered not to be difficult, but there are a good number of subtle safety points that should be learned such as: More than 1/7 the capacity of the cylinder should not be used per hour.
Welding a handle onto a pitcher can usually be done with relative ease. However, when welding a tube to another tube, a combination of blowing and suction, and pressing and pulling is used to ensure a good seal, to shape the glass, and to keep the surface tension from closing the tube in on itself. Sometimes a filler rod may be used, but ...

This is a list of welding processes, separated into their respective categories. The associated N reference numbers (second column) are specified in ISO 4063 (in the European Union published as EN ISO 4063 ). [ 1 ]
Submerged arc welding (SAW) is a common arc welding process. The first SAW patent was taken out in 1935. The first SAW patent was taken out in 1935. The process requires a continuously fed consumable solid or tubular (metal cored) electrode. [ 1 ]

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).
