6 Weld until the joint is completely fused.

Welding is a process that joins two pieces of metal together by melting and fusing them. A welding rod is a long, thin piece of metal that is used to create the weld. 7018 welding rod is a type of welding rod that is made from a combination of iron, chromium, and molybdenum. It is a versatile rod that can be used on a variety of metals, including steel, stainless steel, and aluminum.

This tutorial will teach you how to weld with a 7018 welding rod. We will cover the equipment and materials you need, how to prepare the metal surfaces, how to set the welding machine, and how to weld the two pieces of metal together.

Equipment and Materials

The following equipment and materials are required for welding with a 7018 welding rod:

  • 7018 welding rod
  • Welding machine
  • Welding helmet
  • Welding gloves
  • Welding clamps
  • Grinder
  • Safety glasses
  • Ear protection
  • Welding table

Welding Machine

The welding machine is the most important piece of equipment for welding. It provides the electrical current that is used to melt the welding rod and the metal surfaces.

There are two main types of welding machines:

  • Arc welding machines use an electric arc to create the heat that melts the metal.
  • Gas welding machines use a gas torch to create the heat that melts the metal.

For 7018 welding rod, you will need an arc welding machine. Arc welding machines are available in both AC and DC models. AC welding machines are more versatile and can be used on a wider range of metals. DC welding machines are more powerful and produce a higher quality weld.

Welding Helmet

A welding helmet is essential for protecting your eyes from the harmful rays of ultraviolet light that are emitted during welding. Welding helmets come with a variety of features, such as auto-darkening lenses, headgear, and face shields.

Welding Gloves

Welding gloves protect your hands from the heat and sparks that are produced during welding. Welding gloves are made from a variety of materials, such as leather, cotton, and Nomex.

Welding Clamps

Welding clamps are used to hold the two pieces of metal together while they are being welded. Welding clamps come in a variety of sizes and styles.

Grinder

A grinder is used to clean the metal surfaces before welding and to remove any slag that is produced during welding. Grinders come in a variety of sizes and styles.

Safety Glasses

Safety glasses protect your eyes from flying sparks and debris. Safety glasses should be worn at all times when you are welding.

Ear Protection

Ear protection is essential for protecting your ears from the noise of welding. Ear protection comes in a variety of styles, such as earplugs and earmuffs.

Welding Table

A welding table is a sturdy surface that is used to support the metal while it is being welded. Welding tables come in a variety of sizes and styles.

Preparation

Before you can start welding, you need to prepare the metal surfaces and set the welding machine to the correct settings.

Clean the Metal Surfaces

The first step is to clean the metal surfaces that will be welded. This will help to ensure that the weld is strong and durable.

To clean the metal surfaces, you can use a wire brush or a grinder. Be sure to remove all dirt, grease, and oil from the surfaces.

Inspect the Welding Rod

Before you start welding, you should inspect the welding rod for cracks or damage. If the welding rod is damaged, it will not produce a good weld.

Set the Welding Machine

The next step is to set the welding machine to the correct settings. The correct settings will vary depending on the type of metal that you are welding, the thickness of the metal, and the desired weld properties.

For 7018 welding rod, you will typically use the following settings:

  • Current: 150-200 amps
  • Voltage: 20-25 volts
  • Travel speed: 10-12 inches per minute

Position the Welding Rod in the Holder

The welding rod is held in a holder that is attached to the welding machine. The holder is adjusted so that the welding rod is at a 45-degree angle to the metal.

Put on Your Safety Gear

Before you start welding, you should put on your safety gear. This includes a welding helmet, welding

3. Welding Technique

To weld with a 7018 rod, you will need the following materials:

  • A welding machine that can output 70 amps or more
  • A welding helmet with a dark lens
  • A pair of welding gloves
  • A welding jacket
  • A welding apron
  • A welding rod holder
  • A welding rod
  • A piece of scrap metal to practice on

Once you have gathered your materials, you can begin welding. Here are the steps involved:

1. Prepare the metal. Clean the metal surfaces that you will be welding with a wire brush or sandpaper. This will help to ensure that the weld will be strong.
2. Set the welding machine. Set the welding machine to the correct amperage for the thickness of the metal you are welding. For 7018 rods, you will typically use an amperage of 70 to 80 amps.
3. Weld the joint. Hold the welding rod at a 45-degree angle to the metal. Start the arc by touching the welding rod to the metal and then pulling it back slightly. Move the welding rod along the joint in a smooth, continuous motion. Add filler metal as needed. Stop the arc by touching the welding rod to the metal again and then pulling it away.

Here are some tips for welding with a 7018 rod:

  • Use a consistent speed when moving the welding rod.
  • Keep the arc length consistent.
  • Add filler metal as needed to fill the joint.
  • Stop the arc smoothly.

4. Post-Welding Care

Once you have finished welding, you will need to take care of the weld to ensure that it is strong and durable. Here are the steps involved:

1. Allow the weld to cool completely. This will help to prevent the weld from cracking.
2. Chip away any slag from the weld. Slag is a hard, crusty material that forms on the weld during welding. Chipping it away will help to expose the weld metal.
3. Grind the weld smooth, if desired. Grinding the weld will help to remove any imperfections and make it look more polished.
4. Clean the weld with a wire brush. Cleaning the weld will help to remove any dirt or debris that may have accumulated on it.

By following these steps, you can ensure that your welds are strong, durable, and aesthetically pleasing.
