Repairs to Aluminium Road and MTB frames.
I have been doing repairs on bike frames for quite a while now. On MTB's it tends to be cracks which have appeared over time or maybe since a big collision. On a Road bike frame it's mainly damage to the rear drop-out and derailleur hanger. Todays job was on a Commencal hardtail Mtb frame where the top of the seat tube had broken off completely just above the original weld.
The paint had to be removed from the frame near to where I was going to be welding.
The broken top of the tube was re-attached using ACDC Tig at around 65amps with a 1.6mm 4043 filler rod, the frame material is 6061. I also added a small gusset to the front of the break and extended it along the top tube, hopefully this will help spread the load and prevent any further failures.
Job done and customer happy, he's back on the road or maybe trail.
