Designs are welded

A big variety of welded designs complicates their uniform classification. Welded designs can be classified:
on a way of receiving preparations (sheet, litosvarny, kovanosvarny, shtamposvarny);
to purpose (carriage, ship, aviation, etc. );
to characteristics of their work (beams, frames, farms, capacities, vessels working under pressure, pipes and pipelines, case designs, etc. ).
By consideration of questions of design and production of welded designs it is expedient to classify the last depending on characteristics of work. In this case it is possible to allocate the following types of welded designs.
Beams - the constructive elements working generally for a cross bend; the beams which are rigidly connected among themselves form frame designs.
Columns - the elements working mainly for compression or compression with a longitudinal bend.
