I feel like all I'm doing is science experiments. Too many experiments, not enough work lol.Thanks for performing the science experiment, we all benefit.
So question, if you can spot weld through the adhesive/seam sealer, then why can't you apply seam sealer around the rosette weld holes and then rosette weld? Any seam sealer that would squeeze into the weld area could be cleaned up before welding. I ask as this would be a preferred approach if it can be done. No need to transport the shell to a shop and I have gotten pretty good at plug welding.
Good question. All the weld through sealer and adhesive is actually only for spot welds. They usually say if MIG welding is needed, keep it a couple inches away from the sealer/adhesive, making it not compatible with MIG/Wire Feed/Rosette Welding for a cowl. The welds are too close together.
That's why I'm going to take it to a shop with a digital/timed spot welder. My HF spot welder needs to keep the on time at nearly 7 seconds, which would also get the joint too hot too. The professional spot welders are on for only a fraction of a second and are consistent, which keeps the heat down.
