Welding
built 622 days ago
Welding is an excellent field for creative people who like to work with their hands. It is a challenging career with above average pay. Welders don't just weld. They need to be able to layout and fit up pipe and plate, calculate the length of pipe runs, determine where support bracing needs to be applied and know what quality assurance criteria applies to the work they are doing. A good welder ... knows something about welding symbols, blueprint reading, metallurgy and welding inspection. The courses offered at WWCC will teach all of these subjects and most importantly you will leave WWCC with the valuable knowledge necessary to be a qualified entry level welder.

Welding is a fabrication process that joins materials, usually metals or thermoplastics, by causing coalescence. This is often done by melting the workpieces and adding a filler material to form a pool of molten material (the [W]eld puddle) that cools to become a strong joint, with pressure sometimes used in conjunction with heat, or by itself, to produce the weld. This is in contrast with soldering and brazing, which involve melting a lower-melting-point material between the workpieces to form a bond between them, without melting the workpieces.

Welding rods, used to fuse metal together in the welding process, have been found to release toxic levels of several chemical elements into the air when heated. These chemicals, in the form of fumes and dust, can have serious side effects. The largest number of welding rods side effects are from toxic levels of the chemical element manganese, but adverse side effects have resulted from exposure to chromium and nickel as well. Toxic exposure to fumes and dust from welding rods happens most often in the workplace where safe levels are determined by OSHA (Occupational Safety & Health Administration). For OSHA limits on manganese levels and the dangers of manganese Exposure, see the publication of the National Safety Council.

Welding can create fumes which are a complex mixture of metallic oxides, silicates and fluorides. Fumes are formed when a metal is heated above its boiling point and its vapours condense into very fine particles (solid particulates). Welding fumes normally contain oxides of the materials being welded and of the electrodes being used. If the metal has a coating or paint, these too can decompose with the heat and become part of the fumes. Care should be taken when working near these fumes.

Welding is the most economical and efficient way to join metals permanently. It is the only way of joining two or more pieces of metal to make them act as a single piece.
