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.

动态安全国际是安全设备的创新制造商（例如头盔，听力**保护，眼镜，安全带...）。由于对产品的需求量很高，因此他们通过过程自动化提高了自己的**制造能力。他们目前正在面临有关“自动化的自动化”的问题，用于制造其用于工人跌倒的能量吸收器设备。当前的过程涉及使用工业**缝纫机缝制厚的聚酯编织织带带。这个缝纫步骤很耗时，需要工人的大量手动干预。两个**焊接工艺，超声波焊接和电阻焊接将用于此目的。这些过程将根据其自动化的能力来评估这些过程，同时根据**机械性能满足所有工业需求。
