Welded helical spring Free 3D model

A compact helical spring fabricated by forging multiple layers together at their circumference, rather than through coiling, allows for added versatility and reliability. This method is most effective when mass production is essential or high tensile strength is a must, given its durability to withstand excessive weight stress. Welded construction also makes this type of coil particularly well-suited for supporting immense load-carrying capacity.
