DHIE Welding and Automation Solutions

DHIE designs and manufactures automated welding and assembly equipment, mainly for automotive body and automotive parts production.

Systems can be configured from welding stations using one or two robots to fully automated welding lines using dozens of robots, depending on the required production capacity, workpiece, and factory layout.

In addition to supplying individual machines, DHIE can design complete production systems covering welding processes, robot layout, fixtures, material handling, and control systems.

Supported Welding and Automation Processes

DHIE can build automation systems that combine multiple manufacturing processes.

• Spot Welding

Supports spot welding for automotive bodies, floor panels, pillars, longitudinal beams, reinforcement parts, and other components.

In addition to robotic welding lines, welding stations using one or two robots and manual welding lines can also be designed.

• Arc Welding

Supports robotic arc welding for subframes, seat frames, exhaust components, and other parts.

Robots, welding fixtures, and transfer equipment are combined according to workpiece geometry, weld locations, and required production takt time.

• Adhesive / Sealer Application and Hemming

Supports automatic application of adhesives and sealers, as well as hemming processes for doors, hoods, and similar components.

These processes can also be integrated with welding operations into a single automated production line.

• Peripheral Automation Processes

In addition to welding, systems can incorporate press-fitting, punching, riveting, stud welding, projection welding, conveying, and other processes.

Multiple processes can be integrated into one line according to the required manufacturing sequence.

Design, Simulation, and Control Technologies

• 3D Design and Simulation

3D design and mechanical simulation are used to evaluate robot layout, fixtures, workpiece transfer, and potential equipment interference in advance.

Offline programming is also supported, allowing robot movements and equipment configuration to be reviewed before the actual system is manufactured.

• Mechanical and Electrical Design

CATIA, AutoCAD, and related software are used for mechanical design, while EPLAN is used for electrical design.

PLC, robot, and welding equipment manufacturers can be selected according to the customer’s factory standards and existing equipment.

Equipment is selected according to system specifications and the customer’s factory standards.

Robot Welding Line and Station Applications

DHIE manufactures a wide range of automated welding systems for automotive bodies, subframes, seats, exhaust components, and other parts.

• Automotive Body Longitudinal Beam Spot Welding Line

For automated welding of left and right front longitudinal beams, DHIE has experience with systems using 38 robots.

The system was designed for a production capacity of 36 units per hour with a cycle time of 100 seconds.

• Automated Welding Line for Body Reinforcement Parts

For reinforcement parts used across multiple vehicle models, DHIE has delivered an automated welding line using 14 robots with a production takt time of 60 seconds per unit.

• Subframe Arc Welding Line

For automotive front subframe production, DHIE has experience with an arc welding line using six robots and supporting a production takt time of 120 seconds per unit.

• Robot Welding Station for Exhaust Pipes

For automotive exhaust pipe arc welding, DHIE has built a welding station using two robots with a production takt time of 115 seconds per unit.

Other supported applications include center tunnels, floor panels, wheel houses, doors, seat frames, instrument panel beams, and various other automotive components.

※ The number of robots and production takt times above are examples from individual projects. Actual equipment specifications are designed according to the workpiece, process, and required production volume.
