TIG电弧电流密度分布研究现状和进展
Current Status and Progress of Research on TIG Arc Current Density Distribution
摘要
Abstract
Research methods for arc current density are mainly divided into experimental measurements and numerical simulations.Experimental measurements focus on determining the current density distribution at electrode boundaries.Cathode current density can be measured using methods such as ablation mark analysis and high-speed photography,while anode current density can be measured using split-anode methods,tungsten probe techniques,and arc pressure methods.Numerical simulations are based on fluid dynamics equations and Maxwell's equations,combined with appropriate boundary conditions,to establish a mathematical model of the TIG arc and solve the current density field.Experimental measurements can directly reflect arc characteristics,but are limited by equipment accuracy.Numerical simulations are widely used due to their efficiency and flexibility but rely on simplified physical relationships and boundary conditions.Using appropriate experimental results as validation data helps improve the mathematical model of TIG arc,thus obtaining a more reliable characterization of current density distribution.关键词
