Laser welding is commonly used within manufacturing industry, particularly where it is required to weld steel sheets together using a continuous seam weld.
One such process produces so called 'tailored blanks' for the automotive industry, where two or more sheets of varying thickness are welded together.
After welding the blanks are deep drawn to form a component.
It is vital that the weld quality is maintained at the highest level in this production method.
Tailored blanks are typically used for doors, boot lids, bonnets, longitudinal and transverse supports etc., by most car manufacturers.
They offer significant weight reductions while maintaining overall strength of the component.
The M2D15/10 is a two dimensional laser scanner which continuously monitors and controls quality of the welding process in real time.
Data is fed back to an industrial PC based control system employing software tailor made for each specific application.
Typical measurement frequencies are 100Hz, and the system is characterised by its high precision giving absolute error detection of 40um.
Each system is designed for the particular application after in depth consultation with the user, and supported by continuous development to realise the full potential in use.
Ongoing development of more sophisticated laser sensor equipment is offering important additional enhancements in manufacturing processes, such as greater observation frequency, higher resolution in the Z/K axis, or on-line measurements.
