摘要
采用汉诺威焊接质量分析仪对大理石-萤石型碳钢焊条电弧物理特性进行了研究,发现熔滴的“桥内过渡”是大理石-萤石型碳钢焊条熔滴行为的主要特征,提出以T1>2.05ms时间段内短路频率N与该时间段内累计的短路时间Σ(T1)作为判据,评价大理石-萤石型碳钢焊条的工艺性。
The welding arc physical characteristic of marble-fluor carbon steel electrode was studied by Hannover welding quality analyser. The result showed that ＂metal transition in the slag bridge＂ was the main characteristic of drops behaviors of marble-fluor carbon steel electrode. Process of marble - fluor carbon steel electrode could be evaluated by short-circuiting frequency N and the total of all short-circuiting time ∑ （ T1 ） when the statistic short-circuiting time T1 was more than 2.05 ms
