Can your friend inspect the frame, for this and other possible issues?
At the very least, have your friend ask the seller to remove all 4 bottle cage bolts and photograph all of the rivnuts carefully, if the frame cannot be viewed in person. I would be less likely to buy a ti frame that looked like that without being able to inspect it myself...unless this is a really special frame, there are so many ti frames for sale now, often in truly mint condition. |

Remove the rivnuts completetly and replace, ideally with stainless ones.

A hole drilled in the frame is a stress riser and rivnuts don't reinforce it very well. I had a Trek aluminum bike where the frame cracked through at a rivnut holding on the front derailleur braze-on. I'd rather have a welded boss. |

I was at Moots for ~18,000 frames built with welded in bosses and maybe there were a couple that had issues. Some of those tubes were thin 0.7mm. Just depends how the preparation and welding is done and where they are located IMO.

Bingo. Welding isn't inherently flawed in any way. But it is a process that depends on a certain level of preparation to ensure it's reliable. Same thing goes for rivenuts though.
