Robotic Welding & Automation Systems for Transformer Manufacturing

At Deltasin, we provide complete automation solutions for transformer manufacturing through our strategic collaboration with Robentex, a specialist in robotic welding technologies. Together, we design and deliver turnkey systems that enable precision welding, high repeatability, and scalable production capacity for transformer manufacturers worldwide.

Our solutions cover a wide range of transformer components including main bodies, side walls, full bodies, clamps, covers, flux collectors, and transformer cores. These systems are designed for manufacturers seeking to reduce manual labor, increase production efficiency, and maintain consistent weld quality.

Our robotic welding systems use MIG/MAG processes integrated with gantry-based automation, advanced seam tracking, and offline programming (OLP) to deliver flexible and high-throughput operations.

    Frequently Asked Questions

    What is a gantry welding system?
    A gantry welding system is an automation setup where the robot moves horizontally along a rail-mounted structure. This allows the robot to perform welding operations across large workpieces without moving the part itself.
    What are the advantages of gantry systems compared to fixed robot stations?
    Gantry systems provide a significantly larger working envelope. A single robot can reach multiple weld positions, reducing the need for multiple stations and maximizing efficiency in large-scale production.
    What kind of parts are suitable for gantry systems?
    These systems are ideal for long, wide, or heavy components. They are commonly used in industries such as chassis manufacturing, steel structure fabrication, and large mechanical assemblies.
    How does offline programming benefit gantry systems?
    Offline programming allows welding paths to be created and simulated virtually without interrupting production. For gantry systems working on large and complex parts, this greatly reduces setup time and ensures precise path planning.
    What are the advantages over manual welding?
    Compared to manual welding, gantry robotic systems offer higher consistency, faster cycle times, and reduced operator fatigue. They also improve overall quality and repeatability in high-volume tasks.
    Can Deltasin customize gantry systems for my project?
    Yes. Deltasin offers fully customized gantry solutions tailored to your needs — including rail length, payload capacity, torch type, and software integration.
