Is J-B Weld stronger than welding?

J-B Weld, known as “The Original Cold Weld,” was developed as an alternative to traditional torch welding. It’s designed to be extremely effective in even the harshest environments. Because it’s a two-component (or 2k) epoxy system, it uses reactive chemistry to create the strongest bond possible.
