Fabrication and welding involves making products and components from raw or semi-finished materials by cutting, shaping and joining sections of metal together.  The fabrication and welding industry is embedded in every aspect of the railway industry, from the passenger cars to the manufacture of stillages for component and parts transportation.  Over the years, Gordon Services UK Ltd has manufactured many hundreds of stillages.

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 (an assembly joined by welding, sometimes referred to as “welding assembly” and “welding structures“)  have been ordered, a “welding fixture” may be used to position product parts for welding. This secures the geometry of the product parts. A welder finishes the work according to engineering drawings (for detailed welding) or by their own experience and judgement (if no drawings are supplied).

Special measures may be needed to prevent or correct 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 sand as it cools, and post-weld straightening.

Straightening of warped steel weldments is done with an oxyacetylene torch. In this highly specialised 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, may be line-bored after heat treatment.

Metal fabrication is the creation of metal structures by cutting, bending and assembling processes. It’s a value-added process involving the creation of machines, parts, and structures from various raw materials.

Fabrication shops employ a multitude of value-added processes, including welding, cutting, forming and machining.

Metal fabrication usually starts with drawings with precise dimensions and specifications. Fabrication shops are employed by contractorsOEMs and VARs. Typical projects include loose parts, structural frames for buildings and heavy equipment, and stairs and hand railings.
