摘要

基于生产实际和ISO 3834系列标准（金属材料电弧焊的质量要求），电弧焊过程中，电压和电流是否符合焊接工艺规程（WPS）是决定焊缝质量的关键因素。传统意义上对电焊机电压表和电流表本身的计量，对于焊接过程控制及焊缝质量的保证是无意义的。影响实际焊接过程中电流、电压输出的因素包括电焊机本身，也包括电弧燃烧时，整个回路中的其他组成部分，比如电缆线长短、粗细等。介绍了如何确认电弧实际燃烧过程中如何确认电流和电压，以及基于IEC 60974-14，如何验证评估测量结果，以保证实际焊接电流、电压符合WPS要求，焊接热输入控制在许可的范围内，从而稳定焊缝的质量。

Abstract

Based on production practice and ISO 3834 series standards (Quality requirements for fusion welding of metallic materials)

whether the voltage and current comply with the Welding Procedure Specification (WPS) during the welding is the key factor determining the quality of the weld seam. In the traditional sense

measuring the voltage and current meters of the welding machine itself is meaningless for controlling the welding quality and ensuring the quality of the weld seam. The factors that affect the current and voltage output during the actual welding include the welding machine itself

as well as other components of the entire circuit during arc combustion

such as the length and thickness of the cable. This article introduces how to confirm the current and voltage during the actual arc combustion

and how to verify and evaluate the measurement results based on IEC 60974-14 to ensure that the actual welding current and voltage meet the requirements of WPS

and the welding heat input is controlled within the allowable range

thereby stabilizing the quality of the weld seam.
