Welding is one of the most important applications of technology and has been used in practically every region of the world for centuries. In more recent times, welding has taken a more modern spin, and soapstone is one of the common materials used in it.
Soapstone, also referred to as steatite, has a number of applications in welding. In fact, it’s estimated that nearly 39% of welders in the USA use soapstone in their projects. Let’s find out more about what soapstone is and how it’s used in welding.
What is Soapstone Used for in Welding
Welding is an important operation for fabricating and repairing parts for industrial and consumer markets. However, the process is difficult due to smoke, heat, and intense light being emitted. To reduce the damage that this can cause to the surrounding workpiece and tools, welders commonly use a material called soapstone to mark and guide their welding paths.What is Soapstone?
Soapstone is a form of metamorphic rock, meaning that it has undergone extreme heat and pressure over millennia and is made up of different types of minerals.It is largely composed of talc but also contains other compounds, too. It is a fairly soft material and having a natural temperature threshold of 842 degrees Fahrenheit makes it ideal for welding operations.
What is Soapstone Used For in Welding?
Soapstone is mainly used in welding operations to mark the area of a piece of metal where welding work must be done. With its natural heat resistance, it is safe to use in direct contact with the stainless steel, aluminum and similar materials used in welding.Soapstone is also used to make other markings on the metal surface with a chisel, such as grooves, or as a heat shield material while welding.
What are the Benefits of Soapstone in Welding?
- Soapstone is easy to shape and manipulate in comparison to other metals.
- Due to its heat-resistance, it is safe to use when welding.
- It doesn’t give off the same levels of toxins and heat as other metals when heated up.
- It is an ideal marking tool as it can easily be visible against the metal.
- It is relatively inexpensive.
