一、前言有关合金化镀锌板(下简称合金化板)CO_2短路过渡电弧焊的研究,国外报导甚少,国内亦基本处于空白状态,特别是对该板的电弧现象研究。众所周知,电弧气氛的组分对电弧的电、热物理性能及其稳定性有重要的影响。
I. INTRODUCTION The research on CO_2 short circuit transition arc welding of alloying galvanized sheet (hereinafter referred to as alloy sheet) has few reports in foreign countries and basically remains blank in China, especially the arc phenomenon of this plate. It is well-known that the composition of the arc atmosphere has an important influence on the electrical and thermal physical properties of the arc and its stability.
