Learned a new trick for tube sheet repairs yesterday

So I'm working on this heat exchanger at a plant outside Houston, and the tube sheet had some serious corrosion around the edges. My foreman showed me this method where you use a needle gun to clean out the grooves before you lay down the new weld. Saved me about three hours of grinding by hand. Has anyone else tried this approach with stainless tube sheets?

That needle gun trick works great on stainless if you keep the pressure low and the angle shallow. I've used it on a few jobs at a chemical plant near Baton Rouge and it saved us big time on rework. Just watch out for gouging if you get too aggressive with it.
