Laser spot welding, compared to resistance spot welding, is non-contact and precise, which completely eliminates issues of tip pressure and alignment, resulting in a higher quality product and prevents issues such as indentations and asymmetrical welds, which can result in bacteria growth and visually inferior products, respectively.
Additionally, laser spot welding requires access to only one side of the part, giving more design flexibility. With little heat input, thin parts can be spot welded at significantly higher rates when compared to TIG welding.
Meeting the sanitary and hygienic demands of the food and beverage industry is a complex task. Handheld laser welding and cleaning technology, such as the LightWELD system from IPG, offer significant advantages in food-grade welding. They provide flexibility in equipment design, increased productivity, reduced costs, and improved quality. By embracing this technology, manufacturers can enhance food safety, streamline production processes, and ensure customer satisfaction.
