💡 How do you prep welded leaf hinges for heavy duty trailer box applications?
You knock out a handy weld job by following these straightforward steps.
- Cut hinge plates flat against your frame edge using a plasma torch or chop saw
- Apply high heat welding rods along the contact zone to fuse the metal completely
- Dress the weld seams smooth with a flap disc so paint rolls on even later
- Test the swing path three times full arc before letting the joints cool down
