Micro-Butt welds are generally found in industries such as pipeline and pressure vessel. The joints are characterized by extremely narrow joint, alternative occurrence of edge misalignment and possible irregular tacked points, resulting in poor joint consistency and difficulty in controlling welding accuracy. The Micro-Butt Welding Seam Tracking System developed by Intelligent-Laser can be quickly installed either on industrial robots or special-purpose welding machines, capable of precisely detecting the welding gap as small as 0.08mm. Through visual guidance, the programmed welding path is modified continuously to compensate for position variation to ensure the weld bead is precisely deposited in the joint, achieving accurate and efficient welding process.
The position between the laser sensor and the welding gun is fixed. The sensor extracts the weld features by scanning the geometric information of the weld and workpiece through the beam, then generating three-dimensional points cloud data, and calculating the relationship between the tool of robot and the sensor, which can be used to transform the sensor data to robot coordinate system. As a result, robot is guided to automatically compensate the deviation between the teaching path and the actual weld position, so as to realize intelligent welding.
As a light source, the laser emits a certain wavelength beam and projects it onto the surface of the workpiece to form a laser belt
The high-definition camera module receives the diffuse reflection of the laser strip and takes an image
CUTEWELDER software processes the collected data at high speed through optical algorithms
The CUTEWELDER software converts the three-dimensional feature of the weld into the image, generates structural information such as the position and shape of the measured object, and determines the weld path.
The host control unit provides the welding path to the robot
The industrial robot realizes the adjustment of the teaching and improves the welding quality
