Определение энергетических параметров процесса формирования шва при сварке в защитных газах

Определение энергетических параметров процесса формирования шва при сварке в защитных газах

Abstract

Проведен математический анализ энергетических параметров дугового разряда при механизированной сварке в среде защитных газов. При помощи математического моделирования установлены степени воздействия основных сил дуги на процесс формирования сварного соединения, математически определен баланс сил сварочной дуги. Впервые определен коэффициент, зависящий от материала электрода и параметров приэлектродных областей, позволяющий определять степень влияния плазменных потоков дуги на стабилизацию процесса сварки. На основе математического моделирования получены номограммы, позволяющие находить оптимальное соотношение основных технологических параметров горения дуги для стабильного и качественного формирования сварного шва, которые предназначены для использования в системах автоматизированного (синергетического) управления процессом сварки при разработке современного сварочного оборудования.

The mathematical analysis of the energy parameters of the arc discharge at MAG. Using mathematical modeling established the impact of the main forces of the arc on the formation of a welded joint, mathematically defined balance arc. First defined coefficient depending on the electrode material and the near-electrode regions of parameters, which allows to determine the degree of influence of plasma flows to stabilize the arc welding process. Based on mathematical modeling prepared nomograms that allow finding the optimal ratio of the main technological parameters of the arc for a stable and high-quality formation of the weld, which are intended for use in automated systems ( synergistic ) welding process control in the development of modern welding equipment.
