Abstract and keywords
Abstract (English):
There are offered ratios for the computation of deformation and power modes of yielding at billet pressure welding. A power method is used for the computation of pressure with reference to a flat discontinuous field of movement speeds. Pressure minimization is carried out in a variation way. The assessment of billet material damageability is shown.

Keywords:
