Is JB Weld stronger than welding?

JB Weld, known as « original cold welding », was developed as an alternative to traditional torch welding.it is designed to extremely Effective even in the harshest environments. Because it is a two-part (or 2k) epoxy system, it uses reactive chemistry to create the strongest possible adhesion.

How do you connect cast iron?

Why is cast iron welding difficult?

It melts easily, so why is it so hard to solder?Welding cast iron is difficult because of its high carbon content (about 10 times more than most steels), and it’s brittle and prone to cracking. Relieving thermal stress from the heat-affected zone is challenging, and cracks can grow over time.
