Resistivityconstantandionizationstateofargonarcwithironvapor
Design
procedure of resistivity constant ofwelding arcmulticomponent medium, which is founded on modern plasma physics theory with
approximation of infinitesimality directed
velocityas compared with their thermal velocity, is formulated in the article. Ion
concentrations with different degrees of ionization of arc components are
determined in terms of Saha equations. It’s represented, that solution of combined equation is reduced to determination
of positive root of polynomial, its degree more on unite then number of
different ions’re considering when is reasearching. Resistivity constant of argon
arc with different content of iron impurity is calculated up to 25000 °Ñ.
Terms: arc, iron vapor, Saha equations, ionization
state, resistivity constant.

Simulationofnonsteadyformingofweldingjointswhenimpulselaserwelding
Nonsteadyphysicomathematical
model of forming of welding joints when impulse laser welding was developed, which
lets to make evolution of form of steam-to-gas canal surface and weld pool
surface under the influence laser impulse, for the purpose of studing of mechanism
of defects formation, defects like salience of the welded joint beginning and crater
of the welded joint end. Feature of the model is continuous balance accounting of
melting metal value when melting and freezing, it lets to make features of
nonsteady forming of surface of welding joints. Comparison of calculated welding joint longitudinal and cross
macrosection showed their equivalence.

Structure of transition zone when explosion welding (titanium–orthorhombic
titanium aluminide)
It’s considered
there are «risk zones» during explosion welding. First,this is a choice material
with intermetallic structure like source material, secondly, melting when in
use welding.Though,
the choice of orthorhombic titanium aluminide for welding of titanium is
successful, and welding joint is high-strength. Local melting doesn’t make
brittle structure because of freezed vortices have duplex superdispersed
structure, which has needed flexibility. Therefore «risk zones» are not dangerous,
although usually it’s considered so. In the issue «area of weldability» is
increasing.
Terms: explosion welding, transition zone, vortex
structure, orthorhombic titanium aluminide.

Featuresofarcwhenusetungstenelectrodeweldinginincreasedpressureinertgas
When researchingarc
physical characteristics of tungsten electrode
welding in inert gas their features are established, which shows when increasing
pressure up to 16MPa: increased voltage and arc energy-release, conducting
constricted arc saturation when using small value current, increased heat removal from arc, higher arc voltage drop
and arc emission, also changing arc form when increased pressure. Established regularities
of influence of increased gas pressure on arc properties could be useful for designers
of new welding technologies particularly underwater welding.
Terms: arc welding, inert gas, increased pressure ,
tungsten electrode, arc physical characteristics, arc voltage.
