With a great interest in building a quality of band saw, Siam Splendid Steel Company had a valuable experience by participating in the demonstration, carried by J&T Welding Supply Company on 9th July 2019. The core of this experiment is to detect the imperfection of welding point on the band saw through two methods: Penetrant Testing (PT) and Magnetic Particle Testing (MT)
Penetrant Testing (PT) is an international standard that is widely applied to examine the defect in fusion-welded. To be more detailed, this method is able to identify various flaws on the metal, including surface-breaking, inclusion, micro cracks, gas pore, surface pore, etc. It is very useful as these blemishes are so tiny such that human are unable to detect.
