Clamping the metal pieces together

Once the metal surfaces are clean, you need to clamp the metal pieces together. This will help to hold the pieces in place while you weld them. You can use a variety of clamps to hold the metal pieces together, such as C-clamps, vice grips, or welding clamps.

Positioning the pieces so that they are at a 90-degree angle

The next step is to position the metal pieces so that they are at a 90-degree angle. This will help to ensure that the weld is strong and uniform.

Setting the correct welding parameters

The final step is to set the correct welding parameters. The welding parameters include the voltage, current, and arc length. The correct welding parameters will vary depending on the thickness of the metal, the type of electrode, and the desired weld bead.

Welding Process

Once you have prepared the metal surfaces and set up your welding machine, you can begin welding.

Starting the weld

To start the weld, hold the electrode in your welding hand and touch it to the metal. The electrode will create an arc, which will melt the metal and create a weld pool.

Moving the electrode

Once the arc is established, you can begin moving the electrode. The goal is to keep the arc moving in a straight line along the joint. You should also keep the electrode at a consistent distance from the metal.

Finishing the weld

To finish the weld, you need to let the weld cool and then grind it smooth. You can use a variety of grinding tools to grind the weld, such as a bench grinder, an angle grinder, or a flap disk.

Welding 7018 steel is a relatively simple process, but it does require some practice to get the hang of it. By following the steps in this guide, you can learn how to weld 7018 steel with confidence.

To strike an arc, you will need to touch the electrode to the metal and then pull it back quickly. This will create a spark that will ignite the welding rod.

Once the arc is struck, you can start moving the electrode along the joint.

Move the Electrode Along the Joint

As you move the electrode along the joint, you will need to add filler metal as needed. The filler metal will help to fill in the gap between the two pieces of metal and create a strong weld.

The amount of filler metal that you add will depend on the thickness of the metal and the size of the weld bead that you want to create.

Stop Welding and Cool the Weld

When you are finished welding, you will need to stop welding and cool the weld. You can do this by letting the weld cool naturally or by using a quenching method.

Quenching is a process of cooling the weld quickly by dipping it in water or another coolant. This can help to prevent the weld from cracking.

Inspection and Repair

Once the weld has cooled, you will need to inspect it for defects. Some common defects include:

• Porosity
• Cracking
• Undercut

If you find any defects, you will need to repair the weld. You can do this by grinding down the defect and then re-welding the area.

Tips and Tricks

• Practice makes perfect! The more you weld, the better you will become.
• Use a consistent welding technique. This will help to ensure that you produce consistent results.
• Be patient and take your time. Welding can be a slow process, so don’t rush it.
