An Industrial Member asked TWI to perform a series of trials on a new water-based welding product together with its automated application system. Ceramishield RobotIQ made by TWI Industrial Member Henkel, is a system to apply a dry film coating to protect welding torch components from welding spatter for long periods of time. The coating was to be used in an automated robotic configuration.
The brief from Henkel to TWI was to establish the equipment settings needed to achieve a good coating on the torch components, which would be effective for an extended period of time when compared with typical anti-spatter products. Henkel also asked TWI to assess coating performance and comment on the coating's impact in terms of weld quality, productivity and cost saving potential.
The TWI team optimised spraying conditions and carried out trials to assess the capability of the coating to prevent spatter build-up when used in conjunction with a magnetic torch cleaner. For calibration purposes the team carried out comparison trials without applying the anti-spatter spray. The unit was easily interfaced with the robot used for the trials.
In conclusion, the spray coating performed well and the magnetic torch cleaner removed most of the spatter. Welding was carried out for up to four hours without needing to replace the shroud or contact tip.
