Yes. Cracked saw frames are a common call, the load on a frame near a constantly running blade is brutal and the metal eventually fatigues. We grind out the crack, drill the tip, weld with the right rod, and reinforce the geometry where it makes sense.
Conveyor frames, roller mounts, chain supports, and infeed structures all weld up the same way. We come to the line, work around your operations as much as possible, and get the section back in service.
