New Generation Laser Sensor Increases Quality & Speed of Welding
A new laser sensor has been launched by British manufacturer, Meta Vision Systems, for all types of mechanised and robotic welding. It is the first such sensor to incorporate high performance image processing in the sensor head itself, rather than needing a separate computer, and has many applications throughout manufacturing industry.
The thickness of the steel plates that form the base of a wind tower can be 50 mm or more, while the middle section is fabricated from lighter gauge metal and near the top, the steel is thinner still. Welding of these various gauges requires different procedures. The base is typically prepared with a U joint profile and welding takes place in several passes. The middle section requires a V type joint and is welded in one or two passes. Steel at the top is welded with a simple butt joint preparation. The DLS200 sensor has a fully programmable scan configuration, which means that a wide scan can be used for the U and V joints, but a narrow scan with high resolution can be used for the smaller butt joints.
