What Is Fusion Welding and Why Is It Used? Fusion welding is a welding process that fuses metal together using oxy acetylene gas along with filler material (rod). Oxy acetylene welding uses a torch flame to melt the pipe joint metal, and then you add the filler metal as you weld, fusing the joint. Fusion welding can also be used without filler ...

Fusion welding stands as a testament to the evolution of manufacturing and the pivotal role it plays in shaping the structures around us. We've delved into its intricacies, understanding the myriad processes and their implications. The balance between its benefits and drawbacks remains a topic of ongoing research and innovation.
Fusion welding, as opposed to soldering, melts the base metal and could need a filler material to create a junction. The metal component becomes molten when exposed to high heat. As it cools, these components come together to produce a weld bead. The end product is always more durable than the starting material.
Some people call it fusion welding; the official name for the technique is Autogenous TIG Welding. Specifically, it uses the TIG welding process to fuse two pieces of metal without using a filler rod. Fusion welding has its place in the roster of techniques that welding operators should learn. The biggest questions are how it works when you ...

Learn about the two main types of fusion welding (arc and solid-state) and their advantages and disadvantages, and see common examples of fusion welding processes such as GTAW, PAW and SMAW.
The fusion zone in welding is the bead itself, as well as where the bead connects to the surface. If it is melted metal rather than merely heated, it is a part of the weld fusion zone. Some of the defects that can intrude into this zone are obvious. Porosity and inclusions are often evident to the naked eye, and if they are not, a range of non ...
