You can short it for a brief test, but it is there to prevent it
overheating and potentially a fire.

No you cannot solder it, the heat would melt the solder.

Some sort of mechanical connection is the only way - tiny nut and
bolts, crimps, or point contact welding.

The thermal fuse I replaced in my resistor pack was around 125C and
worked OK for 5+ years afterwards.

On my resistor pack the fuse was physically around 1cm away from the
resistors with an air gap between
