What is Stick Welding: A Comprehensive Guide 2023

What is Stick welding

Whether a welding enthusiast or a professional welder, you can bring life to your metalwork through stick welding. In this article, we will explore what is stick welding. If you are curious about this fascinating art, join us on this journey of uncovering the secrets of stick welding. Let’s dive together.

Stick welding is a versatile and widely used metal fabrication and repair technique. It is also called Shielded Metal Arc Welding (SMAW), in which an electric arc is used to fuse the metal pieces. Understanding the stick welding process can open up a world of possibilities for metal artists.

What is Stick Welding?

Stick welding is a manual technique that uses an electric arc to join the metal pieces. In this welding process, the consumable electrode is called a “rod” or “stick.” The name of this technique is also based on this electrode that contains flux coating.

The electric current pass through the electrode to create an electric arc. This arc generates intense heat that melts the metal that is being welded. When the heated weld pool colds, it solidifies, creating a stronger bond between the materials.

Stick Welding Machine and Equipment

There are a few tools and equipment that are essential for stick welding. You need to have proper knowledge of these tools before embarking on the journey of stick welding. Following are some primary equipment that is used in stick welding:

Stick Welder

A stick welder is the core equipment for stick welding, also known as an MMA welder. It is used to provide necessary electric current during the process of welding. Stick welders come in different sizes and power ratings to cater to various welding needs.

  • Power Source

Different sources, like conventional AC or DC power supplies, can power stick weld these. DC power supplies are more common as DC can provide better control over welding and deeper penetration.

  • Amperage Range

You can select suitable currents for your welding projects by adjusting the amperage range. For thinner materials, lower amperage settings are more appropriate. On the other hand, you can use higher amperage settings for thicker materials.

Electrodes (Sticks)

The electrodes used in stick welding are consumable and contain a flux coating. They are responsible for creating shielding around the weld pool to protect it.

  • Types of Electrodes

Different types and sizes of electrodes suit specific applications of stick welding. The most commonly used electrodes are mild steel, stainless steel, and Aluminum. Each class has different characteristics, like tensile strength, welding position suitability, and unique alloy composition.

  • Flux Coating

Electrodes contain flux that performs various functions. It acts as shielding and prevents the weld pool from atmospheric contamination, thus enduring a clean weld. It also provides additional metal protection by forming a slag layer of weld top.

The Process of Stick Welding

Stick welding includes several steps. Following is the explanation of those steps. If you are a beginner in stick welding, you need to choose the best welder for beginners, and read it carefully, as it’s a free guide for you to learn.

  • Preparation

First, prepare the workpiece and the welding area. Make sure that the workpiece is clean and doesn’t contain any dust or rust. You can use a wire brush or any grinder to remove the impurities from metal pieces. Now, secure the workpiece using the clamps and fixtures so that this can’t move during welding.

  • Equipment Setup

It’s time to set up the equipment required for stick welding. First, you should choose the best welding machine to start your project. Ensure to provide manufacturer-recommended polarity while connecting the welding cables with the stick welder. Connect the work clamp with the workpiece and secure this connection.

  • Electrode Selection

Determine the electrode you must use according to your specific welding application. Since electrodes come in various types and sizes, you should consider factors such as base metal composition, joint type, and different welding conditions while electing one. You can also determine the suitability of an electrode for the intended application by referring to its classification code.

  • Electrode Preparation

Prepare your selected electrode before starting the welding process. Use a grinder or electrode cleaner that removes the 1-inch (2.5 cm) coating from its tip. This will give you a good electrical connection and proper arc initiation.

  • Strike an Arc

After preparing the electrode, you need to position yourself so the welding area is in your clear line of sight. Put on the necessary welding safety gear, such as the best welding helmet with darkened lens, gloves, and protective clothing. Put a strong grip on the electrode holder and strike the arc. You can do this by touching the electrode to the workpiece and lifting it quickly to about 1/8 inch (3 mm) away. The arc initiates the welding process.

  • Welding Technique

Maintain a consistent distance between the electrode and the workpiece to control the arc length. It is an important step as a too-long arc is weak and unstable, while too short an arc length can cause the melting of the electrode or sticking. Now, move the electrode along the joint and create a molten weld.

Different factors, such as joint configuration and weld bead pattern that includes stringer bead, weaving motion, and whip pause technique, can impact the welding technique being used.

  • Molten Weld Pool

When the arc heats the electrode and workpiece, it forms a molten weld pool by melting the metal present in the common area. Here, flux coating protects the weld pool from atmospheric contamination. This flux coating also creates a slag layer to protect the weld upon cooling.

  • Filler Metal Deposition

The metal core of the consumable electrode melts to contribute to the filler metal as soon as the molten weld pool forms. Now, move the electrode along the joint so molten metal can fill the joint and create a stronger bond between the metal pieces.

  • Slag Removal

Cool the weld before removing the slag once the welding is complete. Now, remove the slag with a slag hammer or wire brush. This will expose the weld bead underneath. Perform this process multiple times until the joint is fully welded.

  • Post-Weld Cleaning and Inspection

Clean the welded area thoroughly and remove the remaining debris and slag once you complete welding. Inspect the welded metal and check for any visible defects, including cracks, undercutting, or incomplete penetration. Perform post-welding techniques such as grinding and additional welding passes to achieve the desired weld quality.
