Boodkin Yu. V., Yerofeyev V. A. � Physical and mathematical model of the refractory metal and steel electron-beam welding

Heat conduction equation is selected as the base of the physical and mathematical model for the welded joint formation. The equation boundary conditions take into account the electron beam characteristic. Weld pool melt surface pressure equation is selected as the second equation of the model, and the boundary conditions are determined for it. Pressure equation solution determines the body shape to solve the heat conduction equation.
Key words: physical and mathematical model, electron-beam welding, equation, boundary conditions

Bourkov P. V., Bourkova S. P. �Composite material use forwoodshop tool, obtained by deposit welding

Tool steel consumption reduction feasibility is considered at tool making by creation of twolayer materials, obtained by deposit welding, which allow for reliability and durability considerable increase of the high-loaded components and machinery.
Key words: tool steel, deposit welding, composite materials, reliability and durability

PRODUCTION SECTION

Krampit N. Yu. �CO2-shielded long arc welding stability increase

CO2-shielded long arc welding stability increase technique is suggested, which is attainable by pulsed arc welding application. At pulse pile-up power dispensing is carried out on the droplets melting, starting from the moment of droplet detachment, which is registered by the voltage spike at the arc space. This allows for keeping up equal sizes of the droplets, favours higher process stability and weld upgrading.
Key words: welding, carbon-dioxide gas, power dispensing, process stability
