The increasing usage of aluminium alloys has created further challenges to the welding industry. It allows for an effective weight reduction as they replace more traditional iron and steel materials, but also is more challenging to weld, and thus requires additional measures to ensure a proper process.
The Tailor:Weld project aims to bridge the gap between the need for an affordable and easy to use laser weld technology and the solutions available today. Most existing laser systems are fitted with either a standard process head or a 2D galvanometer scanner – both of which deliver a “standard” Gaussian or “top-hat” energy distribution to the work piece. However, this relatively simplistic energy distribution is not directly suitable for many applications and significant laser welding expertise is required in order to develop acceptable process parameters.
The project WeldaPrime – “Self-repairable Zinc-free Weldable Anti-corrosion Primer for the Steel protection”, sponsored by the EC FP7 Research for the benefit of SME associations (3-year projects) has started on February 1st 2014 and has the European Welding Federation as its project coordinator.
