本文介绍了用于熔覆的新版 MIG/MAG 工艺的开发。这项工作继续进行营销术语中所谓的“冷加工”。这就是为什么将此新版本的验证与冷金属转印 (CMT) 版本进行比较的原因。该新版本采用电源提供的交流电（AC），能够调节所有电气变量，从而可以在改变极性的同时满足电弧重燃的要求，并确保金属转移的稳定性。焊接试验针对的是火电厂水冷壁覆层的使用。开发的版本呈现出 CMT 的共同特征，并且对于涂层应用而言很有趣：低焊接功率和沉积材料的低稀释度。此外，所开发工艺的良好稳定性和润湿性，以及与 CMT 版本相比的高生产率，证明了其在通过焊接涂覆金属涂层方面的潜在用途。
This paper presents the development of a new version of the MIG/MAG process for use in cladding. The work continues with what in marketing terms is known as “cold processes.” That is why the validation of this new version is compared with the cold metal transfer (CMT) version. This new version uses alternating current (AC) provided from a power source which has the ability to regulate all the electrical variables, so that it is possible to meet the requirements for reignition of the arc while changing the polarity and also ensure the stability of the metal transfer. The welding tests were aimed at the use of water wall cladding in thermal power plants. The version developed presented characteristics that are common to CMT and interesting for the application of coatings: low welding power and low dilution of the deposited material. Furthermore, the good stability and wettability of the developed process, together with the high productivity in comparison with the CMT version, demonstrate its potential use for applying metallic coatings by welding.
