Welding Practice
Welding Rod
"Use 5356, 5180 or 5183 fillers for welding 7005 frames.", Easton. "5356/5180/5183" Columbus
"Al Mg Si 05 (USA 6063) - CASTO MAG 45802" CeeWay.
Welded Up
Ageing - Heat Treating
Columbus
Frames in 7000 alloy.
The ageing of the frame realized in 7000 alloy has to be carried out 4/5 days after the welding, in two phases: 6 hours at 90°C ±5° - 4 hours at 150°C ±5°.
Easton
Artificial age for 7005 frames:
Age 6 hours at 200 degrees F (± 10 degrees F) plus 4 hours at 320 degrees F (±10 degrees F). This process
must be performed by the builder on all Easton 7005 tube sets.
