The weld access hole or rat hole is a structural engineering technique in which a part of the web of an I-beam or T-beam is cut out at the end or ends of the beam. The hole in the web allows a welder to weld the flange to another part of the structure with a continuous weld the full width on both top and bottom sides of the flange.
Gusset plates are usually square or rectangular, but can be triangular or made into a customized shape to fit the joint. The shape of each plate is designed so that welding or bolts can be applied to different edges of the plate. [2] A gusset plate can form the entire connection or it can be used in conjunction with bolts or welds. [2]
Most weld purging is carried out on joints made by the TIG or GTAW arc welding process. [6] When the laser welding process is chosen, joints or welds being made on reactive materials will need to be carried out and in the case of electron beam welding, this is carried out in a vacuum, in which case purging takes place by complete evacuation of all gas.
Lally column – is a round thin-walled structural steel column oriented vertically to provide support to beams or timbers stretching over long spans. The steel shell of a Lally column is filled with concrete. Lightening holes – Limit load (physics) – Limit state design – Linear elasticity – Lintel – Live load – Load bearing ...

Cellular beam is a further development of the traditional castellated beam. [1] The advantage of the steel beam castellation process is that it increases strength without adding weight, making both versions an inexpensive solution to achieve maximum structural load capacity in building construction.
It's the most wonderful—and stressful—time of the year. While the holiday season can be joyful, gatherings with family, friends, and colleagues inevitably come with some awkward encounters.
Workers welding in parking garage. Welding is the main focus of steel fabrication. [8] 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 ...
