How To Select And Use The Best Cutting Wheel For The Job
- Oct 26, 2018 -

A good weld starts with good preparation, 

and good weld preparation starts with a clean cut. 

But cutting is an art that requires both skill and knowledge 

of how to select and use the best cutting wheel for the job.
The type of cutting wheel to use for a given application 

depends largely on what material will be cut. 

However, at the end of the day, 

there is no substitute for proper technique 

when it comes to gaining cost savings and productivity.
Welders will always prefer a cut line that is smooth and consistent to make a clean, strong weld joint 

with as little filler metal as possible. 

The goal when cutting any material is always to use the fastest and sharpest method to cut smoothly and without contamination or smearing. 

This is important because a smeared surface can prevent reliable fusion of the joint during welding.
The biggest challenge welding operators face when choosing the right wheel for the cut is whether speed and smoothness are the priority, 

or whether durability is most important. 

Lower cost wheels generally have softer bonds — 

offering a smooth, fast cut.  

Because the bond is softer, these wheels are typically less durable. 

On the other hand, harder wheels offer exceptional durability but tend to cut more slowly. 

Finding the balance between speed, life and cost is often the biggest challenge, 

and simply selecting the least expensive wheel option can end up costing the user valuable time and money.
