SUSTAINABILITY IN MANUFACTURING
SUPPLEMENT LASER WELDING – THE ENVIRONMENTAL BENEFITS
health are significant concerns, it’s good to know that laser welding is a cleaner process producing far fewer emissions and pollutants. Being highly versatile and adaptable to various
materials and applications, laser welding allows manufacturers to optimise processes leading to more efficient production methods.
The laser welding advantages of speed, precision, accuracy, low thermal distortion, and versatility deliver significant environmental benefits too. Laser welding offers businesses higher
productivity than traditional methods and not just because it is faster and more precise. The entire process is designed to offer environmental benefits that contribute to sustainable manufacturing processes and hence, a greener future.
ENERGY SAVING Where environmental benefits are concerned, energy is an obvious starting point. Laser welding is inherently more energy efficient than traditional alternatives such as MIG and TIG. MIG and TIG welding invariably require high
energy inputs to generate the heat necessary for welding. In contrast, laser welding’s focussed laser beam requires significantly less power to
achieve its precise and accurate welds. Less energy consumption means it is better for the planet, along with lower costs.
REDUCED MATERIAL CONSUMPTION Traditional methods often require filler materials, generating more spatter and resulting in higher waste and greater material consumption. As a non-contact process, laser welding creates a minimum of material waste, contributing to resource efficiency. Being more accurate and precise, it reduces the need for rework or additional processing which would require additional energy usage and material consumption. Lower Emissions and Enhanced Air Quality:
Traditional methods also involve the use of gases and fluxes that can release harmful emissions into the atmosphere. In industries where air quality and worker
CONCLUSION The laser welding advantages, such as reduced waste generation, enhanced efficiency, cleaner operation, and minimised emissions, make it a compelling choice for manufacturers. With many industries aiming to meet sustainability goals and accreditations and reduce their environmental impact, laser welding is a positive step forward in meeting these objectives. TLM Laser offers high end welding solutions such as the IPG LightWELD for fabrication and AlphaLaser products for precision welding.

SIEMENS SELECTED FOR MULTI-PHASE DECARBONISATION PROGRAM AT HEINEKEN PRODUCTION SITES
As part of its ambitions to reach Net Zero in Scopes 1 and 2 across all production sites by 2030, international brewer HEINEKEN has selected Siemens as a partner for its global Net Zero Production roadmap. The company’s will work together on a long-
term decarbonisation program which will see Siemens implementing solutions and services from its Xcelerator portfolio, to reduce energy usage at more than 15 HEINEKEN beer and malt production sites across Asia-Pacific, the Americas and Europe. Additional sites will be added in a second phase. HEINEKEN and Siemens collaborated on an initial project of consulting, auditing, and advisory services, using an energy digital twin to simulate and analyse a typical HEINEKEN brewery in the virtual world, identifying where significant energy savings could be made. The simulation showed approximately 70% of energy use was linked to the generation of heating and cooling necessary for the brewing process. By optimising and monitoring these cooling and heating systems through an end-to-end program, Siemens estimates energy savings of between 15-20% at each site, and an average CO2 reduction of 50 percent at each site. Dolf van den Brink, HEINEKEN CEO and chairman of the executive board, said: “As we continue to focus on the delivery of our journey to reach Net Zero in Scope 1 and 2, we know that we must make many bold and ambitious moves
to decarbonise our global operations. Undertaking these challenges with partners like Siemens allows us to bring in technical expertise and industry knowledge to innovate quickly and at scale. We are excited to continue on this journey with partners who are committed to pioneer and localize next-generation solutions, to help us reach our net zero goals.” To achieve targeted reductions in energy
usage and CO2, Siemens will deploy an end-to- end program of solutions and services which are scalable and replicable across HEINEKEN’s global production sites. Using operational data in combination with the energy digital twin at each site, Siemens will design, engineer and implement a system to electrify the production of heat and cooling using heat pumps powered by renewable energy, reducing reliance on steam generated by fossil fuels. The system will be monitored, controlled and optimized using Siemens Cooling Plant Optimization algorithms, which uses built-in analytics to analyse data from the plant to reduce energy costs and ensure operational efficiency. As part of the long-term partnership
agreement, Siemens will also deliver a five-year performance and monitoring
contract, connecting the breweries to Siemens systems which use data services to remotely monitor the production sites, ensuring the best solution is operated at all times. “We’re proud to be a partner to HEINEKEN’s
Net Zero roadmap; an ambitious journey to reach Net Zero by 2040,” said Matthias Rebellius, managing board member of Siemens AG and CEO of Smart Infrastructure. “Working with HEINEKEN as a partner in this way demonstrates a thoroughly modern approach to data-driven decarbonisation. By collaborating on an end-to-end program, we’re able to combine hardware, software and analytics to predict and deliver the long-term results which are now crucial to every industry.”
