Dynamic Safety International is an innovative manufacturer of safety equipment (e.g. helmets, hearing**protection, glasses, harnesses...). Due to the high demand for their products, they are increasing their**manufacturing capabilities through process automation. They are currently facing a problem regarding the**automation of a critical step for the manufacturing of their energy absorber device used in worker fall**protection. The current process involves sewing thick polyester woven webbing straps with an industrial**sewing machine. This sewing step is time consuming and requires a lot of manual intervention from workers.**In this project, we propose to change the way in which the webbing straps are attached by welding them. Two**welding processes, ultrasonic welding and resistance welding, will be used to that end. The processes will be**evaluated based on their capacity to be automated while meeting all industrial requirements in terms of**mechanical performance.

Dynamic Safety International是一家创新的安全设备制造商（例如头盔，听力保护，眼镜，安全带等）。由于对其产品的高需求，他们正在通过过程自动化提高其制造能力。他们目前正面临着一个问题，关于制造用于工人坠落保护的能量吸收装置的关键步骤的自动化。目前的工艺包括用工业缝纫机缝制厚聚酯编织织带。这个缝纫步骤很耗时，需要工人进行大量的人工干预。**在这个项目中，我们建议改变织带的焊接方式。为此，将使用两种焊接工艺，即超声波焊接和电阻焊接。这些工艺将根据其自动化能力进行 ** 评估，同时满足 ** 机械性能方面的所有工业要求。
