1612 CNC Stud Welding Machine

In modern sheet metal manufacturing, productivity depends on the ability to combine speed, flexibility and consistent quality. Companies producing different components in limited batches need automation systems capable of adapting quickly while maintaining high welding standards. The ATSCDI1612 CNC stud welding system has been developed to provide a reliable and efficient solution for manufacturers looking to automate the installation of welded studs and improve the overall performance of their production process.

Designed for capacitor discharge stud welding (CD stud welding), the ATSCDI1612 combines CNC positioning technology, automatic stud feeding and intelligent welding control to deliver accurate and repeatable results. The system allows manufacturers to move away from manual operations and introduce a fully controlled welding process, reducing production variability and improving efficiency.

With a compact 1600 × 1200 mm working area, the ATSCDI1612 is particularly suited to companies requiring a flexible automation platform without the footprint of larger industrial systems. Its design makes it an ideal solution for sheet metal fabricators working with changing production requirements, multiple component geometries and demanding delivery schedules.

The machine has been engineered to handle a wide range of fastening applications, including threaded studs, smooth pins, threaded bushes and customised fixing elements. Using capacitor discharge technology, it provides strong and clean welds on materials such as mild steel, stainless steel, aluminium and galvanised sheet metal, making it suitable for industries where appearance, reliability and repeatability are critical factors.

A major advantage of the ATSCDI1612 is the combination of high production output and process flexibility. The system can achieve welding speeds of up to 25-30 studs per minute, while maintaining precise positioning and consistent weld quality. This makes it suitable for both repetitive production runs and applications where frequent changes between different components are required.

The CNC architecture controls the complete welding sequence, from positioning the welding head to managing the final cycle parameters. High-quality mechanical construction, precision linear guides and servo-driven movements ensure positioning repeatability of up to ±0.02 mm, providing manufacturers with stable production results and reduced risk of defects.

To meet different production requirements, the ATSCDI1612 can be configured with multiple automatic welding heads. Standard solutions are available with up to three heads, while customised configurations can integrate up to six independent welding units. Different head technologies, including direct feeding, angled feeding and universal CD/ARC solutions, allow the machine to adapt to a wide range of stud types and welding processes.

The automatic feeding system has been designed to maximise reliability during continuous operation. Sensors verify correct stud positioning before each welding cycle, preventing empty cycles and reducing the possibility of production interruptions. This approach improves process stability and helps manufacturers achieve higher levels of productivity.

For demanding applications, the system can include advanced process monitoring functions, such as welding current control. This allows the machine to identify abnormal conditions during operation and stop the cycle when required, supporting consistent quality control and reducing the risk of non-conforming parts.

When working with galvanised materials, the ATSCDI1612 can be equipped with an automatic zinc removal solution. By combining controlled surface preparation, air cleaning and anti-spatter protection, the system improves weld quality and reduces the need for additional finishing operations after welding.

Operator efficiency has also been considered in the machine design. The modular worktable includes retractable support elements, adjustable pneumatic clamping systems and positioning references to simplify component loading and ensure stable fixing during the welding process. These features allow faster setup times and easier management of different component configurations.

The ATSCDI1612 is managed through an industrial control platform with touchscreen interface, providing an intuitive environment for programming, monitoring and production management. CAD and NC file import, cycle simulation, production data monitoring and network connectivity support integration into modern digital manufacturing environments.

The system is suitable for a wide range of applications, including electrical cabinets, industrial enclosures, electric vehicle charging stations, energy storage systems, lift components, HVAC equipment, medical devices, household appliances and precision metal assemblies.
