A complete practical guide that can be used to train the pile driving as well as supervisor. Sincere appreciation to the team developed for their thinking, time to compile and share !
Magnetic Particle Inspection (MPI), also known as Magnetic Particle Testing (MPT), is a non-destructive testing (NDT) method used to detect surface and near-surface discontinuities in ferromagnetic materials, such as iron, nickel, cobalt, and some of their alloys. Here's why it's particularly useful for inspecting welding: Detection of Surface and Subsurface Defects: MPI is effective in identifying both surface and just-below-the-surface discontinuities. In welding, this includes cracks, porosity, incomplete fusion, and other inconsistencies that might compromise the integrity of the weld. Immediate Results: MPI provides immediate visual results. The presence of any discontinuities is indicated by the accumulation of magnetic particles at the defect site, which can be seen directly. This immediacy aids in the quick assessment of the welding quality. Minimal Preparation Required: The surface preparation for MPI is relatively simple compared to other methods. The area needs to be clean, but extensive preparation is not necessary, making it a quick and efficient process for weld inspection. Sensitive to Small Defects: MPI is highly sensitive to small surface cracks and other discontinuities that might not be visible to the naked eye or could be missed by other NDT methods. Applicability to Complex Shapes: The method can be applied to complex geometries that are typical in welded structures. The magnetic field and the particles can conform to the shape of the object, making it versatile for inspecting welds in various configurations and positions. Cost-Effective: Compared to some other NDT methods, MPI is cost-effective, especially for the detection of surface and near-surface discontinuities. Its efficiency and speed also contribute to its cost-effectiveness. No Hazard to the Component: MPI is a non-destructive test that does not harm the material's structure or future usability, making it ideal for routine maintenance and inspection. In summary, Magnetic Particle Inspection is a crucial technique in welding to ensure the quality and integrity of welds, particularly in critical structures where strength and safety are paramount.
Usually, we are using Cooling Agents in the construction sites, in order to speed up the work. In that case, we may wait 2 to 3 minutes only. If we didn't use the cooling agents, we need to wait until the weld gets cold naturally. It will take 30 to 45 minutes.

@Ravi Thank you for your compliments.
🎉
a very helpful video in details to visualize the steps in piling, interesting, good job!
Glad it was helpful!
Thank you very. You just saved my time. I have a job interview presentation and was unable to visualize the driven pile.
Glad it helped!
Thanks
Welcome
Mantap squer pile
why square pile joint welding far much better compared to round concrete pile? is it the welder or the geometry?
It all about the welder.
When to strop the strike? How do we know that we are going to stop?
We have a set calculation to terminate the driving of pile. Check the playlist. We already have a video on this. Thank you.
is this same with displacement pile precast concerete ?
Please provide method statement for this procedure with technical data.. thank you...
Noted. We will try to do a video by including Method Statement as well.
,,,,,❤
Thank you so much

Not available
I don't believe the piles don't crack when driving them into the ground. I wouldn't use them.
14,000 PSI Concrete piles work just fine.
How long should wait after welding
Usually, we are using Cooling Agents in the construction sites, in order to speed up the work. In that case, we may wait 2 to 3 minutes only.
If we didn't use the cooling agents, we need to wait until the weld gets cold naturally. It will take 30 to 45 minutes.
Bad back sound. I dislike it
Thank you for your comments. We try to reduce the background sound.
very bad
piless are circular bad civil engineer
Hope you are new to the construction filed.
