Solutions
BBW has relied on lasers from TRUMPF since 2005. Hans Bürger, Co-CEO Director of BBW and father of Andreas Bürger, explains: "No matter what we had in mind, TRUMPF was always with us. With flexible and innovative solutions. At the same time, laser technology has continued to develop rapidly." Since then, BBW has regularly invested in the latest laser systems on the market and is constantly expanding its portfolio. BBW buys the laser sources from TRUMPF and designs the required systems itself in the company's own development department, depending on requirements and customer projects.
Implementation
BBW has a metallurgical laboratory to ensure that the components are produced as faultlessly as possible. At the start of each project, employees also carry out a detailed feasibility study and analyze initial tests in their own laboratory. BBW often directly takes over several process steps in laser processing and even post-processing through to the production of entire assemblies. "And when the current technology puts limitations on what we want to achieve, we start researching," says Andreas Bürger.
In an international research project with the Central Innovation Program for SMEs (ZIM), they worked on improving the welding of mixed aluminum-copper joints. The result? Their joining process largely prevents the metals from mixing in the seam to form undesirable intermetallic phases, i.e. alloys. Their own development project "Weldshape" was dedicated to welding hot cracks in aluminum alloy AW6060, which is very susceptible to such weaknesses. The solution process is based on dynamic beam shaping on a self-built laser system with a 16kW singlemode laser and high-performance scanner. This is because BBW is so advanced in terms of laser technology that beam shaping is also becoming a thing of the past for them.
