Gas metal arc welding (GMAW) processes are used in a wide range of applications due to their high productivity and flexibility. Nevertheless, the supplied melting wire electrode leads to a coupling of material and heat input. Therefore, an increase of the melting rate correlates with an increase of the heat input by the arc at the same time. A possibility to separate material and heat input is to use an additional wire, which reduces penetration and worsens the wetting behaviour. Consequently, bead irregularities such as bonding defects or insufficient root weldings can occur. In the context of this article, a controlling system for a two-dimensional magnetic arc deflection is presented, which allows to influence arc position as well as material transfer. The analysed GMAW hot wire process is characterised by high melting rates while also realising a sufficient penetration depth and wetting behaviour.

利用二维电弧偏转开发高生产率的GMAW热线工艺

气体保护金属电弧焊（GMAW）工艺具有很高的生产率和灵活性，因此被广泛应用。然而，提供的熔丝电极导致材料和热输入的耦合。因此，熔化速率的增加与电弧同时输入的热量的增加相关。分离材料和热量输入的可能性是使用额外的金属丝，这会减少渗透并恶化润湿性能。因此，可能会出现不规则的焊缝，例如粘结缺陷或根部焊接不充分。在本文的上下文中，提出了一种用于二维磁弧偏转的控制系统，该系统可以影响电弧位置以及材料转移。
