Structural integrity comes from highly repeatable positioning and welding. The challenge is to increase productivity even as you increase quality. Our advanced pneumatic and electric welding controls achieve superior profiles for the highest quality weld in the shortest time. And our electric and hydraulic controls and linear-motion products help move chassis and bodies through the shop with accuracy and speed.
Challenges
- Speed production
- Get fast, programmable changeovers
- Automate intelligently
- Achieve higher levels of repeatability
- Increase efficiency with lean manufacturing for manual operations
- Increase quality, reduce rework
- Network efficiently for information-based production

Intelligent welding system programmable for widest variety of profiles - Rexroth Resistance welding controls are the first choice among auto manufacturers, Tier 1 suppliers, and welding-equipment makers worldwide.
The reason is increased process reliability, reduced rework costs, and consistent weld quality. The modular system includes an AC or DC inverter, frequency transformers, a choice of electric or pneumatic gun drives, and control software and interfaces for all popular fieldbuses.

Pneumatic weld gun control Our closed-loop solution for controlling weld guns uses our fast-response, direct-acting E/P valves and directional control valves to give precision and reliability. A closed-loop equalization control valve provides in-depth feedback about the welding process. The efficient system uses considerably less air than open-loop approaches and provides industry-leading repeatability.

Control axis movement to thousandths of an inch - Get more capabilities and flexibility in open- and closed-loop control, including the unique ability to nest loops. Closed-loop operation means greater precision, faster cycle times and unmatched repeatability.
VT-HACD series hydraulic axis controllers are available in application-specific configurations to give you fast designs, quick changeovers, and precise control. They also allow you to save energy through active damping that permits smaller cylinders and higher flows.

Easy to plan, quick to install - Machine and perimeter guarding that’s easy, attractive, and effective in meeting even the most stringent safety standards. EcoSafe is easy to plan, quick to install, and integrates easily with other structures made from Rexroth framing, such as conveyors, ergonomic workstations, and custom machinery.
Panels assemble fast and easily from standard components. Partitions can be constructed of wire mesh screens, protective panes, or panels, then mounted directly into T-slot profiles that have already been integrated into a system.

The complete solution for automating tightening applications - The System 300's multiple spindle design accommodates up to 40 tightening channels. The system includes a range of controllers, drives, software, communication options, and spindles, with the flexibility and precision to tighten to exact the torque specified.
The programmable system integrates easily into your factory information system, gathering such critical data as time, date, torque applied, angle, number of turns, and other user-selectable information.
