The article presents the rationale of using the method of pulsed laser exposure during the operation of coronary stent delivery system components welding. The author discussed the parameters of pulsed laser radiation, affecting to the quality of welding joint. In view of these parameters performed modeling of pulsed laser welding.

Statement of the problem. Preparation of high-strength foam concrete in construction allows for energy and resource conservation. Water covers more than 50% of their dense component and on its properties depend strongly on structural properties of foam concrete, is not fully explored.
Results. The effect of mixing water of low temperature on the structure and properties of constructive penofibrobetonov. Recommendations on the account in the calculation of reinforced concrete elements elevated structural properties and deformation diagrams penofibrobetonov by mixing water setback.
Conclusions. Using low temperature mixing water improves the structure, increases the strength, deformability and elastic modulus, as well as changes of the deformation diagram fibropenobetonov.
