EFFECT OF FLUXES ON TEMPERATURE AND CURRENT DENSITY IN THE ARC COLUMN IN TIG WELDING OF TITANIUM | 2 |
| The effect of barium, calcium, magnesium, sodium and aluminium fluorides, which are the main components of welding fluxes used for TIG welding of titanium, on temperature of the arc column and its distribution in the anode region has been studied. It has been found that in TIG welding over the flux layer (TIG-F) the temperature and electrical conductivity of the arc column plasma increase and shape of the temperature field in the anode region of the arc is close to the cylindrical one. Deep penetration characteristic of this welding method is caused by higher temperature and current density in the arc near the anode. | |

ARGON-ARC TREATMENT OF WELDED JOINTS ON 30KHGSA STEEL | 6 |
| Effect of parameters of conditions and thermal cycle of a local argon-arc treatment without melting on changing the metal structure and mechanical properties of the high-strength steel welded joint was studied. It is shown that the arc heating within the wide ranges of treatment speed up to the temperatures of austenization of the welded joint metal, being hardened during welding, causes the repeated hardening, while at the temperatures below the austenization temperatures a short-time tempering is occurred. After the local argon-arc treatment the ductility and impact strength of the welded joint metal are increased, the mode of fracture is improved, the sensitivity to stress raisers is decreased. | |

EFFECT OF SURFACE MICRORELIEF ON ADHESION STRENGTH OF THERMAL SPRAY COATINGS. | 18 |
| Current concepts of the role of parameters of microrelief of the substrate surface in formation of thermal spray coatings are analysed. The analytical model developed on the basis of analysis of experimental data is suggested for selection of optimal parameters of microrelief of the spray coatings. | |

IMPROVEMENT OF METHODS AND MEANS OF PROTECTION FROM WELDING AEROSOLS | 26 |
| The paper presents a review of works conducted at the E.O. Paton Electric Welding Institute concerning welders's protection from the harmful effect of welding aerosols. The need in an integrated approach, i.e. the combination of technological and sanitary-technical measures with a use of effective means of individual protection of respiratory organs of the welders, is substantiated. | |

OBJECT-ORIENTED PROGRAMMING OF SYSTEMS OF WELDING TECHNOLOGICAL PROCESS CONTROL | 33 |
| The use of object-oriented programming in the development of systems of welding technological process control is considered. A fragment of the electron beam welding installation is selected as an example of a complex object of control. The object-oriented analysis is made, the diagram of relations and synchronizing is plotted and a conceptual solution for the network control system of the automated system of welding technological process control is suggested. | |

IMPROVEMENT OF TECHNOLOGICAL CHARACTERISTICS OF PLASMA-MIG SURFACING USING FLUX-CORED WIRE | 43 |
| Peculiarities of proceeding reactions between some components of the flux-cored wire during plasma-MIG surfacing process were considered. It is shown that the presence of halogenide compounds in arc column favours stabilization of the process of the consumable electrode arc self-adjustment. The formation of boron trifluoride in the flux-cored wire core at the stickout during heating improves the weld bead formation. | |
