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.

CNC turning and milling is the process of holding a material in a spindle, with a cutting tool removing layers from the material. This approach works best for cylindrical items such as rods and tubes, and shafts. The cutting tool cuts in a linear motion while the material undergoes high-speed rotation. This makes it easy to shape, drill, and thread exactly how it is required. Modern turning centers support multi-axis operation, enabling more complex work. It is extensively used in the automotive, aerospace, and mechanical industries.
