So i searched through old threads and didn't find as much about this subject as I thought I would. So I have learned about Techno-Weld and Muggy weld and then there is of course the Tig (hiring it out, right?) Muggy weld is 100 a box but looks like a great product. Techno is 27 dollars a box and seems kinda difficult with the two braising rods. But does any one want to give their own feed back on how well they work. The local welding shop quoted 120 a hour for whatever kind of welding needed, prep time included of course. To me only heating a quarter to half of the melting point of the metal to make the weld wouldn't that be just a surface weld. I am no welder even though I have one so I am talking from things I have read. I would think the 3200psi welding strength both companies claim would make minor fabrication in a boat rebuild very convenient..........and I need to weld my keel
