Haprotech Lasopleidingen (HLO) (Welding Training Courses) is situated in Velsen-Noord, where it has modern training facilities for both practical and theoretical welding education. The welding courses can also be given in-company anywhere in the Netherlands. Both day and evening training courses are available, all of which can be concluded with a certificate recognised by NIL (Netherlands Institute for Welding Technology).

Our welding teachers have broad practical experience and have been trained theoretically to the level of welding specialist. This makes it possible to employ just one teacher for both practical and theory classes. The students work with the latest generation of welding equipment and have their own 'welding box'. The maximum size of the group in our welding training courses is approximately eight students.
