Various types of welded structures exist, each for specific engineering and structural purposes. The most common ones include framed structures, trusses, beams, columns, and space frames. Framed structures are conventionally adopted in the design of buildings because they are capable of withstanding both vertical and lateral loads. Trusses are very common in bridges and roofs since they can maximize weight distribution as efficiently as possible, while using minimal materials. Intellectual constructions and high-rise constructions experience heavy loads with the help of welded beams and columns. Space frames, in contrast, are lightweight, three–dimensional carpentry structures that are very efficient for large span roofs.

Metal bending covers techniques of shaping either a flat or a structural metal part at an angle, curvature, or channel. Press brake bending is the most popular technology, employing a punch and die to apply pressure on metal sheets. Roll bending is applied for mild bends and large curved lengths of sheet metal or structural beams. Air bending provides flexibility with reduced tools because it does not compel a full sheet into a die. Bottoming gets more accurate results in thicker materials because it uses exact die angles. V – bending is also well spread and appropriate for most common uses. Every procedure is picked depending on the material’s thickness and the required quality.
