To create a strong and reliable metal structure, you should decide on the grade of steel, draw up technological maps and a set of drawings. metalworking has a much broader meaning than it might seem at first glance. The process of making metal structures has become much easier in the past few years. Special machines for laser and plasma cutting appeared, which practically minimized the human factor. Laser cutting is more accurate than plasma cutting, although it costs a little more. These treatments are common for sheet metal of almost any thickness.
There are also automated milling machines that can process a workpiece with great accuracy in 2, 3, 4 and five planes. The result is a detail of the required, even the most complex shape, which will only have to be sanded.
Welding work must also be performed in compliance with all required standards, since the reliability of the entire structure depends on the quality of the seam. Welding of simple carbon steels can be performed using a conventional semiautomatic device, but the stainless steel will have to be welded with argon.
Bending operations of sheet metal should be performed with high accuracy, since the accuracy of the dimensions of the structure will depend on the correct bending. This is very important, since the joining of individual elements can be broken if the flexibilter is mistaken by a few millimeters. The experience of the bending machine operator also affects compliance with the design dimensions, since a spread of several millimeters can lead to difficulties when installing the finished assembly on site.
