Analysis of welded defects unambiguously shows that a significant percentage of defects is due to poor quality of metal preparation. The correction of defects in the finished product is a time-consuming and technically complex operation and does not always lead to full restoration of the specified properties of the welded joint.

Dressing

Preliminary rolled products for welded structures are subjected to straightening and deburring to remove impurities and irregularities that arose after rolling, transporting or storing the metal. Plate is straightened in a straightening mill, while stripping is performed in a shot blasting machine or in a special pickling and passivation tank.

Deburring

The base metal at the welding spots should be cleaned from rust, oil, moisture, a loose layer of scale and other contaminants that could lead to the formation of pores and other defects in the seams.

Deburring

Edges are subjected to mechanical processing on edge-blending machines. If necessary, cold bending of metal or bending in heated condition is used. The choice of one or the other method is determined by the thickness of the metal and the radius of curvature of the roughness.

Heat treatment

If necessary, the parts before welding are heated to 200 - 300 °C, and after the operation - annealed to eliminate residual stresses in the weld.
