### Step 1: Preparation.

Before operating a roll overlay welding machine, you need to carefully inspect the machine to ensure it is in proper working order. Check for any loose or damaged parts that may need to be repaired before use. Additionally, make sure you have the necessary safety equipment on hand, such as welding gloves and a face shield.

### Step 2: Setting Up.

Once the machine is in good condition, you can begin setting it up for operation. This includes adjusting the welding parameters such as voltage, amperage, and wire feed speed according to the type of material and thickness of the roll being welded. You should also prepare the welding wire and electrode that are suitable for the specific application.

### Step 3: Welding Process.

To start the welding process, position the roll overlay welding machine in the desired location and secure it in place. Next, turn on the machine and adjust the welding settings as needed. Begin by striking an arc on the surface of the roll to be welded and start moving the welding torch in a consistent motion along the surface.

### Step 4: Overlay Welding.

As the welding torch moves along the surface of the roll, the welding wire is continuously fed into the molten pool, creating a welded overlay that bonds to the base material. The overlay welding process helps to build up the surface of the roll, adding strength and wear resistance to extend its lifespan.

### Step 5: Cooling and Inspection.

After the welding process is complete, allow the welded overlay to cool down before inspecting the quality of the weld. Check for any defects or imperfections that may require additional welding or finishing. Once the overlay has cooled sufficiently, the roll can be put back into service.

By following these steps and properly operating a roll overlay welding machine, you can effectively repair and strengthen rolls used in various industrial applications. Remember to always prioritize safety and follow recommended welding procedures to ensure the best results.
