    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.

    Transformer Main Body

    The main body is the structural foundation of a transformer. It requires highly durable and consistent welds to maintain mechanical integrity over time. Our robotic welding systems are designed to perform high-precision MIG/MAG welding on steel panels used in transformer bodies, supported by gantry systems that allow multi-axis reach and movement. Seam tracking, real-time monitoring, and OLP-based job setup enable fast, repeatable, and error-free production.

    Transformer Side Walls

    Side walls play a crucial role in the strength and shape of the transformer enclosure. Robentex systems provide fully automated robotic welding for side walls, offering fast welding cycles, accurate seam joining, and modular fixture design to support varying panel dimensions. These systems improve welding consistency, reduce rework, and lower operational costs.

    Transformer Full Body Assembly

    Our full-body welding systems are designed for large-scale transformer assemblies where all body panels—main shell, side walls, clamps, and bases—are welded in a single, integrated robotic cell. The system includes programmable gantry structures, multi-axis welding arms, and automatic fixture positioning to enable efficient production of large transformers with minimal human intervention.

    Transformer Clamp and Cover Welding

    For clamps and covers, Robentex solutions include dedicated welding fixtures and compact robotic arms optimized for precision welding on smaller parts. These systems ensure accurate alignment, strong weld joints, and minimal thermal distortion—factors critical to the proper sealing and operation of the transformer.

    Transformer Flux Collector Welding

    Flux collectors often require complex weld paths due to their geometry and material thickness. Our robotic welding cells are customized to handle high-complexity flux collector assemblies with pre-configured routines, adjustable fixtures, and high-performance welding torches. This ensures minimal splatter, high weld penetration, and long-lasting results.

    Transformer Core – Cutting and Stacking by Canwin

    The transformer core is the magnetic heart of every transformer, and its quality directly affects the overall performance and efficiency of the system. For this critical component, Deltasin partners with Canwin, the leading Chinese manufacturer of transformer core processing systems.

    Canwin specializes in the cutting and stacking of electrical steel laminations for transformer cores. Their systems use CNC-guided high-speed cutting lines to shape silicon steel sheets with precise dimensions, followed by automatic stacking solutions that ensure tight assembly tolerances and low core losses.

    As Deltasin's official technology partner, Canwin enables us to offer our customers the industry’s most advanced core production systems—ideal for both power and distribution transformer manufacturers.

    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.
