THE CHALLENGE
The client had a 250T excavator working in an iron ore mine in the Pilbara region of Western Australia. Substantial cracking had developed around the slew ring and track frame mounting areas in the car body so the machine had been tagged out of service due to safety concerns and the ramifications should the component catastrophically fail.
THE APPROACH
The Schlam Engineering team were mobilised to site and our welding engineers worked in conjunction with the OEM technical advisers to determine the best in situation repair method.
The repair was conducted without the need to substantially disassemble the machine as our technicians utilized the latest in heat input control technology to control heat parameters of the parent metal and interpass temperatures. Together with safe welding practices and suitably matched welding consumable, out team executed the task without incident.
THE RESULTS
The welding repair was subject to NDT on completion, which it passed without a single defect. The excavator returned to work and three months later, a follow up NDT test was completed and the repair was found to be successful.
