CRC-Evans Vision System

November 2010 Vol. 237 No. 11

CRC-Evans Automatic Welding is introducing a new generation welding system incorporating laser vision welding and inspection technology.

Said to be engineered to reduce total time of the pipeline welding process while increasing weld quality, the Vision System provides what the company terms remarkable flexibility in the field. Components of the Vision System include the V Weld – an external welding machine with adaptive weld technology; the V Bevel for bevel inspection at the beveling station; the V Root for root inspection at the welding station; and the V Purge – a fully automatic purge control system to control and monitor the purge chamber parameters. All use laser vision technology. Shankar Rajagopalan, e-mail:,
