本文报道了水下湿式焊接参数和条件对自保护药芯焊丝焊接熔敷金属中扩散氢含量的影响。根据 Plackett-Burman 设计，使用甘油法测定熔敷金属中的扩散氢含量，确定伸出长度、焊接电流、电弧电压、行进速度和水盐度的影响的显着性。熔敷金属中扩散氢含量的测量结果为25.85～44.12ml/100g。所有测试因素的影响均具有统计显着性。还建立了一个方程，其分析表明，通过技术方法不能将氢含量降低到21ml/100g以下。 (C) 2017 年氢能源出版物有限责任公司。由爱思唯尔有限公司出版。保留所有权利。
This article reports the effect of underwater wet welding parameters and conditions on the diffusible hydrogen content in deposited metal for welding with a self-shielded flux cored wire. The diffusible hydrogen content in deposited metal was determined using the glycerin method according to the Plackett-Burman design determining the significance of the effect of the stick out length, welding current, arc voltage, travel speed and water salinity. The results of the measurements of the diffusible hydrogen content in deposited metal ranged from 25.85 to 44.12 ml/100 g. The effect of all the tested factors is statistically significant. An equation was also developed, the analysis of which showed, that the hydrogen content cannot be reduced by technological methods below 21 ml/100 g. (C) 2017 Hydrogen Energy Publications LLC.
