As discussed in our previous article Preheating temperature distance range preheat is really necessary in steel welding to control the cooling rate.  More specifically, preheat is used to slow the cooling rate down in order to prevent excessive hardness in the … Continue reading How to determine preheating exemption in welding?

A submersible pump is an equipment that pushes the fluid to the surface instead of pulling it out. This pump has a sealed motor coupled with the pump’s body that pushes the liquid to the surface. Submersible pumps are mainly … Continue reading What is Submersible pump

Example of balancing a huge fan with much more vibration than first one. Result after repair: Vibration went from 3.1 mm/s to 0,2mm/s. Total 1,6kg was needed to get it perfect 🤩 #vibrationanalysis #vibrationtesting #balancing Continue reading Vibration test example
