Wire Erosion – Bar Production
Project Name: Wire Erosion – Bar Production
Industry Sector: Subsea
Type of Work: Wire Erosion
A request was made by one of our clients working in the subsea industry, for 5 bars to be wired eroded from one larger round bar. The bars needed to be wire eroded to a specific diameter. The material being used for this project was Inconel 625 forged billets. Inconel 625 is a superalloy which is frequently used in the subsea industry because it can withstand high stress and a wide range of temperatures both in and out of water.
The large round bar that we started with at the beginning of the process is shown in one of the photographs included. You can also see the cuts that were wire eroded to create the 5 smaller bars from it.
The reason that our client approached us was because the combination of the diameter that they needed, coupled with the material they wanted the bars to be made in, was not available at the time. Even if they waited, due to the lack of availability, to try and buy bars made of Inconel 625 to the diameter that was required was very expensive.
Our client realised that it would be quicker and more efficient to wire erode the bar rather than trying to source some Inconel 625 forged billets to the required diameter. Taking this approach meant that our client was able to save both time and money, rather than having to wait for the required material size to become available. It was also more cost effective having the correct diameter of bar wire eroded instead of using an oversized bar. This cut down on waste which was especially important given that we were using such an expensive material!
Work Carried Out:
For this project we used the Sodick AG600L and Sodick AG600LH. Using these machines, we were able to wire erode the large round Inconel bar into 5 smaller round bars. With this technology we were able to achieve the specific measurements required by our client. Using the AG600LH we were able to extend the capacity to 500mm thick.
We are aware of all the standards and certifications set by different industries, and we adhere to them. In this instance, when creating 5 bar subsea components we ensured that they met with subsea certifications.
At Cheshire Wire Erosion we also recognise that ongoing investment in industry leading technology is essential. Having the most up to date machinery means that we can wire erode components specifically to our client’s requirements.
We understand that a lot of our clients must work to tight deadlines, consequently we will always endeavour to make waiting times as short as possible. We also work with our clients to ensure we come in on budget as well as identify cost effective solutions.
