Advanced solutions

Welding Systems

CRC Evans’ cutting edge automatic welding systems are lightweight and robust, built to work well in constrained spaces and with high reliability. Designed for high productivity, our advanced systems incorporate laser technology for thru-the-arc tracking with inline inspection capability that allow corrections to be made in the critical path, with fully digital control components.

Purge Control System

Fully automated pressure-based purge control system with laser vision. V-Purge controls and monitors purge chamber parameters and inline inspection.

Internal Inspection System

Internal inspection system with vision laser sensor and charge-coupled device (CCD) color camera. Allows root inspection directly after root and hot pass welding, minimising the downtime associated with third-party equipment.

We prioritise the health and safety of our people and aim to reduce incident risk through safe working practices and a quality-driven work environment
