What is a welder fabricator? Welding Fabrication of a metal refers to the building of metal structures. This is done via a variety of processes such as cutting, bending, profiling, welding, and assembling. Metals such as steel, aluminum, and other ferrous and non-ferrous metals are used in the fabrication process then is finished off with our powder-coating paint finish.
Welding is the main focus of steel fabrication. 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 detailed welding) or by their own experience and judgment (if no details are provided).
Special measures may be needed to prevent or correct the warping of weldments due to heat. These may include redesigning the piece to require less welding, employing staggered welding, using a stout fixture, covering the weldment in the sand as it cools, and post-weld straightening.
The straightening of warped steel weldments is done with an oxyacetylene torch. In this highly specialized work, heat is selectively applied to the steel in a slow, linear sweep, causing the steel to contract in the direction of the sweep as it cools. A highly skilled welder can remove significant warpage this way.
Steel weldments are occasionally annealed in a low-temperature oven to relieve residual stresses. Such weldments, particularly those for engine blocks, can be line-bored after heat treatment.
