Innovation is paramount

That is why we carry out our own research and development in the area of Wire Arc Additive Manufacturing. We have developed a method for 3D printing using a welding robot, which could become the new manufacturing technology. This method can be used in:

  • Non-standard and small series machine parts where conventional forging and casting technologies are limited. It increases reliability and reduces errors and delivery times. 
  • Hybrid parts that combine burnout and cladding to save scrap after machining. 
  • Other components with complex shapes, short delivery times or local alternative material properties to improve wear and corrosion resistance, for example. 

It enables the manufacturing of reliable components that were physically impossible or commercially infeasible to produce before. 

  • Focus on safety and quality
  • An innovative approach to discover new methods that benefit our customers
  • Equipped with automatic welding machines, tractors, manipulators, beveling and welding robots
  • Certified for 3D printing
  • Capable of welding larges volumes using an automatic submerged arc welding (SAW)
  • Capable of welding WELDOX 700 and HARDOX 400
  • Production capacity of 6000 m², including cranes with a maximum load capacity of 120 tons to process large structural units
  • The processes are compliant with IWE, IWT, IWS
  • Registration and traceability of the material is guaranteed for each processed item
  • Certified QC and NDT personnel inspects the product quality

Manufacturing offshore crane hooks using 3D printing

Currently, crane hooks are often manufactured by casting or forging techniques. However, in 2018 Huisman delivered the world’s first class-certified 3D-printed crane hooks with an own printed weight close to 200 kg. It ensures superior quality that competes with forgings and castings. It successfully passed its load test (80mt) and all associated quality control checks according to the strictest criteria.
