As shown in the photo, having a set of pneumatic tools to remove corrosion is not enough. Some simple surface preparation techniques are needed to achieve a good and efficient treatment result.
Even simple surface preparation techniques are needed to achieve a good and efficient treatment result. Teaching and providing the crew how to use proper surface preparation tools is very important as they sail into highly corrosive environments. The investment for shipping operators to purchase tools for treatment will always result in significant savings.
On the other hand, the left side shows the result of using an ordinary grinder which leaves a much better preparation result. Edges have been feathered properly and rust was almost completely remove leaving a near white metal result. With this simple demonstration, it clearly proves that having a bit of knowledge with the different results for using grinders versus both cup brush and chipper could lead to efficient and lasting results.
