为了提高焊接熔敷率,又要保证焊缝质量,可以采用在埋弧焊中添加金属粉末的方法。本文介绍了这种方法的出现和发展情况,并阐述了几种向焊接区域中添加金属粉末的方法以及其各自的优势与劣势。这种方法确实可以在不增加焊接热输入的前提下,提高埋弧焊接的熔敷率。
In order to improve the welding deposition rate, but also to ensure the quality of the weld can be used in submerged arc welding method of adding metal powder. This article describes the emergence of this method and its development, and describes several ways to add metal powder to the weld area as well as their respective strengths and weaknesses. This method can indeed increase the submerged arc welding deposition rate without increasing the welding heat input.
