Welding Terms You Should Know 

You might not often think about welding. However, almost every single thing you utilize relies on welding. This makes it a vital component of everyone’s life. You might want to learn a little more about the process if you’ll have to hire a welding company in the future. With this, you will not overwhelm yourself with information when you’ve got to hire one.  


Welding utilizes a lot of hot liquid metal and hazardous tools. This makes it even more crucial for you to know a couple of various terms related to welding. Before you hire a mobile welding Louisville company, here are welding terms you should know: 

Arc Cutting 

This is a method of cutting metal by utilizing heat from an electric arc. During the manufacturing process, the product might require plasma arc welding, gas tungsten arc welding, gas metal arc welding, or shielded metal arc welding.  

Plasma arc welding is the same as gas tungsten arc welding. However, it has a much higher temperature. Gas tungsten arc just gets its name from utilizing a tungsten electrode. With gas metal arc welding, a constant-feed wire offers the filler metal directly from the torch’s tip utilized to weld. Shielded metal arc welding utilizes a protective slag that produces a gas shield that blocks oxygen. 


The process that hardens steel is called tempering. It also helps in enhancing elasticity. During the procedure, a welder will reheat the metal and then lets it cool again. The joint might also have to be tempered even if the metal utilized during welding was already tempered. This will help guarantee that it’s durable enough.  

Welders might utilize other procedures to boost the metal in other methods. For instance, annealing actually softens metal. This often results in the metal losing tensile strength. Meanwhile, stress relief might be utilized to redistribute the stress and make a metal a lot more durable.  

Base Metal 

The piece of metal you’re cutting or welding is called the base metal. It is really very vital to know what form of base metal is being utilized. This will help you pick properly the filler metal. The metal that’s melted to weld together the metal pieces is called the filler metal. The wrong filler metal can lower the overall strength of an item. This might not matter for something small. However, it can be dangerous for a car or a skyscraper.  

The base metal’s tensile strength is one of the most crucial measurements when picking a filler metal. For instance, the filler metal also has to be at least 60,000 psi or more if the tensile strength of the base metal is 60,000.  


You can’t simply glue together metal pieces to build your product during manufacturing. However, you could utilize heat to melt metal and link two pieces together. This is what welding is all about.  

A lot of products you utilize today need welding to manufacture. This includes appliances, buildings, cars, and much more. The truth is that welding is extremely vital that it offers around 50% of America’s gross national product.
