Piston Rods

Piston rods are critical for engine operation. Any damages or wear on the piston rod running surface may lead to excessive lube oil consumption and contamination.

All the piston rods upon receipt are calibrated for diameter, surface hardness, and roughness.
The best method currently available for piston rods reconditioning to original dimensions and hardness is without a doubt Laser Cladding.

Using laser cladding ensures perfect weld quality and a product with the correct hardness.
Find out more information on our laser cladding capabilities.

Piston rods reconditioning procedure:

  • Piston Rod pre-machining for old material to be removed
  • Piston rod preheating before welding
  • Piston rod rebuilding by Robotic Laser Cladding on the running surface using special hardfacing metal powders
  • After stress relieving we perform piston rod machining and piston rod MPI check
  • Final piston rod grinding and verification of dimensions as per maker’s standards
  • Hardness achieved HB 500
  • Piston rods not originally hardened can also be reconditioned by submerged arc welding
