AM fast train part 5
Challenge completed!
Bastien GERARD, Group Business Development Director Consumables at Welding Alloys France, tells us all about this great adventure:
“Welding Alloys have a wealth of expertise in the development and manufacture of flux cored #welding wires. With more than 50 years of experience, Welding Alloys are well positioned to provide tailored solutions dedicated to increasing resistance to wear such as abrasion, erosion, friction, impact and more.
Innovation is part of the DNA at Welding Alloys. Cored welding wires are continuously developed, to provide unique solutions capable of solving even the most challenging wear problems faced in many industries.
In the railway industry, crossings or frogs are subject to daily metal-to-metal wear and impact. Consequently, they become worn and there is an increased risk of damage or potential breakages. Refurbishment by weld rebuilding is a solution that saves time and money. Restoration and repair of the crossing can be swiftly carried out in-situ, resulting in reduced maintenance downtime and track closures, and increased cost savings.
However, at a certain point, the crossings will need to be replaced. The old crossing is then recycled. Wire Laser Additive Manufacturing (WLAM) provides a new way of recycling crossings and frogs in the workshop, offering a better solution for the #environment.
This case study partners Welding Alloys’ advanced cored wires with the high-tech equipment from IREPA LASER and highlights the advantage of WLAM in the regeneration of an old crossing initially allocated to waste.”
Congrats to the team!

- Ready to start manufacturing!
“No specifical tool is necessary to install the part, we just lifted it and put it on the machine table. I took my references on the part and I’m ready to start, just must select my robot program and press “cycle start”.
After 10 hours, the rail is repaired, the built geometries match perfectly with the rail profile. All the data as TCP position, wire feeding speed, laser power, traveling speed are saved during the operation. It guarantees the process according to the qualification parameters and gives us the opportunity to identify any deviation or defect during the deposition. Learning from those data after any manufacturing operation allows us to improve process knowledge and skills and make it evolve.”

The challenge goes on…
Nathan Mayer, our engineer, takes us on our latest additive manufacturing journey…
- It’s time for simulation!
“The CAM part will be simplified due to several advantages of our WLAM process:
- Close to the final dimensions
- High deposition rate possible ➝ beyond 600cc/h
- Low dilution and manageable heat input
- Good mechanical characteristics
Exaggerating a bit, with the right deposition parameters, it will be like generating a path for a 3D printer. Once the building strategies are selected, the parameters filed and the trajectories generated, it’s time to apply some rules to our robots and simulate the operation to avoid any singular point or collision. The part is long (approximatively 2 meters) and the volumes to build are long too, so I generated the toolpath to have the longest deposition tracks and few “off-moves”.
Parameters and toolpath trajectories verified, I can post process my robot program and go back from the numerical world. Rail must now be installed on the machine and repaired!”

Nathan Mayer, our engineer, takes us on our latest additive manufacturing journey…
- Preparation is done, let’s make a clean 3D model!
“For the further operations, it’s important to have a clean 3D model with the missing volumes on the part well defined and smooth. Nothing difficult with a CAD software for an advanced designer. We need to extract to worn faces from the STL and “stretch” them to the initial dimensions.
Before any CAM operations, working parameters must be known and the quality of the deposited material checked. To set them, I will do a quick test to identify a window of working parameters with which we get:
- “Good” linkage with the support
- No defect (lack of fusion, crack, porosity, etc…)
- Constant deposit geometry
- Acceptable deposition rate (the key to have a fast operation…)
To check all of this, build samples are cut, polished, and etched to observe them under microscope. It will be also interesting to check to hardness “as deposited”, to identify any deviation from the material datasheet.”

AM fast train part 1
Hello new challenge!
Nathan Mayer, our engineer, takes us on our latest additive manufacturing journey…
- Day 1: first exchanges
“We’re contacted by the company Welding Alloys France, a global leader in the production of advanced welding consumables, automated welding equipment for wear protection, the provision of engineered wear services, as well as wear plates, pipes, and components.
Their issue? They need to repair a worn #railway that has lost its geometry and they decided to go with the laser technology, most precisely additive manufacturing, instead of most conventional technologies.
Today, repairing or rebuilding parts are major players in increasing service times, avoiding waste and reducing carbon emissions. Railways are subject to heavy loads and many cycles; they must be hard and resistant over time and after 28 years, this one has significant missing elements, it is no longer new… To be used again, we must return to the original shape.
Can we really do it? Can we return to its original shape? Is the reconstruction going to be as resistant as the original one? Only time will tell but we’re up for the challenge.”
- Day 2: first reflexions
“Laser metal deposition or the DED additive manufacturing process offer many possibilities and one of them is to be able to deposit on an existing part. Instead of building complete parts, it is possible to rebuild and repair existing ones. Our wireframe laser additive manufacturing (WLAM) process will hopefully be able to help us with the reconstruction and gives back the used railway its original shape.
As for the material for the reconstruction, it must be just as resistant as the original. After a conversation with Welding Alloys France, they tell us they can provide us with the best yarn to fit this application. It is a manganese #steel that hardens on impact. This filler material is commonly used with conventional welding processes, and I think it will be interesting to show the results obtained with our deposition process, using wire and a laser.”
- Day 3: preparation
“As a first step, the rail must be prepared before the repair operation. So, the team starts to gouge and grind, but also learn its geometry by 3D scanning and digital reconstruction. Everything goes smoothly and we’re quite hopeful for what comes next.”
