When dealing with expensive and vital commercial parts that help your equipment run properly, you need to pay special attention to fatigue and stress factors.
A commercial part that is wearing down and showing signs of fatigue could impact your productivity and cause problems for your equipment. Additionally, a stressed part could lead to problems for the other parts in your equipment.
Consider the benefits of using shot peening to prevent fatigue and residual stress from negatively impacting the performance of your equipment.
How Does Shot Peening Prevent Fatigue?
It is important to routinely review the condition of your commercial parts to identify any fatigue cracks that have formed. Then, if you do identify cracks, you need to consistently measure the size of the cracks to capture the rate of expansion.
When you combine a steady rate of expansion with a slow down in productivity due to the part not performing at the highest level, then you should consider treating the part.
Shot peening the surface of the part will slow the growth of fatigue cracks, extending the life of the part and helping to re-accelerate productivity.
While shot peening is primarily used to prevent fatigue cracking of old and worn down parts, you can also take a proactive approach using shot peening to increase the fatigue strength of new parts.
Before placing a new part into service, consider taking a step back to proactively treat the part with shot peening. The pre-treatment approach will help reduce the amount of maintenance work that will be required down the road.
The Benefit: You can slow down the rate of fatigue cracking in old parts and reduce the likelihood of cracks forming in new parts by using shot peening.
How Does Shot Peening Prevent Residual Stress?
As old or damaged parts begin to wear down, they show signs of stress corrosion cracking. If left unattended over time, the part could be compromised, which means potentially having to replace the part.
You do not want to be in a position where you need to replace a part because of the high cost of the replacement part and added costs from production delays.
- Shot peening prevents residual stress by introducing compressive stress on the surface of the part. This eliminates the residual stress that is causing the part to wear down and not function properly.
- Shot peening helps re-distribute the stress on a part. After a part is shot peened, the residual stress level decreases, allowing the part to stabilize.
- Shot peening is a useful preventive method to reduce stress on the surface where future stress could accumulate.
The Benefit: You can address the current condition of your part and prevent future residual stress to extend the life of your part and improve long-term productivity.
