The frame design is a farm with continuous walls from sheet material, a welded design. Beams happen time of personal section - from dvutavrovy to box-shaped. They are applied on the subcrane ways of bridge cranes, in bridges, platforms, in various constructions and blockings of industrial and civil engineering.

Beams collect on racks, stands, in conductors and various other devices, but if nature of production single, then on a marking.

Beams differ in the big extent of seams, even on length of edges which happen to 1,5 m therefore their welding is often made by automatic machines under gumboil or in protective gas, or in mix of gases: argon (85%) + carbon dioxide (15%) is when the steel alloyed and increased requirements to quality of welding.

In beams at first butt seams (are also carried out especially at assembly joining), then - the others. Stiffening ribs in beams, as a rule, cook on the one hand and not on all perimeter of an end face of an edge.

Edges in a beam establish for giving of bigger stability to a wall which height happens to 1 m and more. If there are no stiffening ribs, then the beam on a wall can cave in under working loading and lose stability. Purpose of edges - only rigidity giving therefore durability of welded seams has to be within stability of an edge and excessive seams will only worsen a design excess heating and internal tension. In frame designs there should not be seams across a beam not to create an overheat zone about a seam from welding which considerably will worsen operational qualities. One more basic addition - should not be seams with the closed contour (like a ring seam).
