I have a Flexsteel accent chair prurchased in the 1970s. The spring unit is the blue steel type. One of the bands has broken where it crosses a brace. Does anyone know if it can be welded back together and be useful for many more years?

The chair is the size I need for my living space and I want to have it reupholstered but I have to solve the spring issue first. If the spring isn't repairable would it be possible to replace it with hand-tied coil springs?

Thanks for helping!
