Good evening all,
I have been asked to repair a cast axle on a Genie Z135 cherry picker and wondered if any of you more technical minded folk may be able to shed some light on the figures I have been given below?
The axle had apparently had a chunk knocked out of it and a poor weld repair had been completed by someone else.
I did not see the axle beforehand but my client has had a forensic engineer onsite to grind away the poor welding and the take samples of the axle for testing (figures below) although apart from suggesting pre heat and post heat he has told my client to allow myself to decide on the best welding procedure
He did agree that the repair is not structural but more of an aesthetic repair so it is just a case of building up to the original shape of the axle. I was thinking tig brazing would be best but would any other type of rod work or even weld method (MIG or MMA?)
C Si Mn P S Cr Mo Ni Al As B Co
0.33 0.31 1.25 0.027 0.010 0.23 0.26 0.25 0.01 0.005 0.002 0.01
Cu Nb Pb Sn Ti V W
0.03 0.016 0.008 <0.01 0.06 0.02 0.04
This yields a carbon equivalent (CE) value of 0.68%
Thanks
