RDT Welding Technology: Megmeet's further research in CMT!

In the realm of modern welding, technological advancements have consistently pushed the boundaries of efficiency, precision, and weld quality. Cold Metal Transfer (CMT) zero-spatter high-speed servo arc welding technology has emerged as a remarkable innovation in the field. In this article, we will explore the concept of CMT welding technology, and its advantages, and delve into Megmeet's pioneering Retract Droplet Transfer (RDT) Welding Technology, which takes CMT welding to new heights.

I. Definition of CMT Welding Technology.

Cold Metal Transfer (CMT) welding is an advanced arc welding process that combines the benefits of Metal Inert Gas (MIG) and Tungsten Inert Gas (TIG) welding techniques. It involves controlled droplet transfer and a specialized welding current waveform to achieve exceptional results. CMT welding facilitates the intermittent transfer of small droplets from the electrode wire to the base material, resulting in reduced heat input and minimized spatter. CMT welding processes are usually performed by a welding robot.

II. Advantages of CMT Welding Technology.

1. Reduced heat input: CMT welding minimizes the heat-affected zone (HAZ) and distortion in the base material, making it suitable for thin sheets and heat-sensitive applications.

2. Reduced spatter: The controlled droplet transfer of CMT welding results in minimal spatter, reducing the need for post-weld cleanup.

3. Improved gap bridging: CMT welding technology exhibits excellent gap-bridging capabilities, ensuring reliable and robust welds.

4. Precise heat control: The ability to precisely control heat input in CMT welding allows for increased weld quality and reduced material distortion.

CMT is crucial in the welding field due to these advantages, but the equipment needed for CMT welding is complex, implementing CMT welding may require specialized equipment and additional setup compared to traditional welding processes. In addition, CMT welding techniques require operators to acquire specific knowledge and training to optimize the process effectively.

III. Megmeet RDT Welding Technology Bring CMT to a New Height.

As the benchmark of advanced arc welding technology, CMT welding technology has always been highly concern for welding professionals. However, the core technology in this field has been tightly dominated by European and American counterparts, and China welding machine manufacturers have rarely been involved, thus Megmeet Welding Technology, one of the best welding equipment designers and manufacturers in China, took the first to make a breakthrough in this aspect and launched RDT (Retract Droplet Transfer) Cold Metal Transfer Zero-Spatter High-speed Servo Arc Welding Technology.

Megmeet has always adhered to independent research and development and has output multiple patented technologies during the R&D of this product. This product has also set a record for the highest quantity of patented technologies used in a single product by Megmeet. It incorporates a comprehensive range of patented technologies, including ultra-low heat input current waveform fine-control technology, molten droplet necking prediction technology, molten droplet fine-control technology, energy dissipation, an efficient recovery system, microsecond-level polarity switching patent, microsecond-level dynamic response multi-node industrial fieldbus control technology, high-precision high-frequency motor and drive algorithm for reverse rotation.......

Supported by so many advanced welding technologies, Megmeet's special arc welding technology of cold metal transfer zero-spatter high-speed servo has a variety of advantages such as:
