Similarly, of mining equipment relies on a variant: thousands of overlapping puddles of tungsten-carbide-rich rod, creating a surface like a crocodile’s back. That’s puddle welding at industrial scale.

As Jack continued to work, he started to develop a rhythm. The motion of the torch became almost meditative, and he began to feel the metal responding to his touch. The puddles formed and cooled, creating a series of small, rounded welds that seemed to grow stronger with each pass.

As Jack packed up his gear and headed home, he knew that he had found a new passion. The art of puddle welding was more than just a technique – it was a journey, a process of discovery and mastery that would challenge and reward him for years to come.

Offers excellent seismic ductility and handles cyclic loads well.

Excessive heat can create oversized holes that fail to fuse.
