THERMAL-PHYSICAL PECULIARITIES OF GAS-SHIELDED PULSE-ARC WELDING USING NON-CONSUMABLE ELECTRODE (Review)

摘要

The work studies the main problems of development and possible perspectives for further improvement of inert-gas non-consumable pulse-arc welding. Main technological possibilities and thermal-physical peculiarities of the process are given depending on variation of welding mode parameters. Considered are the directions for development of methods of mathematical modeling of welding process and possible ways of their improvement. Necessity in further investigations of the process for determination of parametric dependencies and development for engineering and scientific purposes of optimum modes of pulse-arc welding using tungsten cathode was grounded.
