Welding

Welding is the key focus of steel fabrication.

The parts that have been formed and machine will then be assembled and tack welded into place and then checked again for accuracy. It is possible a fixture may need to be used to locate the parts for welding if multiple weldments have been ordered.

The welder will then continue to finish the welding against the engineering drawing if the welding is has a detailed plan, or against their own judgment on the chance no details have been given.

Precautions may need to be taken to prevent any warping of the weldment due to the heat. It may call for a re-design of the weldment to use less weld, welding in a staggered fashion, using a stout fixture, covering the weldment in sand during cooling, and the straightening operations once done welding.

The straightening of steel weldments that have warped would be done with an Oxy-acetylene torch; heat would be applied to the steel in a linear sweep in a slow motion. The steel should have a net contraction, once cooled, following the direction of the sweep.
