Stick Welding vs Mig: 2025 Beginners Simple Guide

When it comes to welding, two commonly used methods are stick welding and MIG (Metal Inert Gas) welding. Both methods have their own advantages and disadvantages, making them suitable for different applications. In this guide, we will provide an overview of stick welding and MIG welding, discuss their differences, and help you understand which method is better suited for your needs.

What is Stick Welding?

Stick welding, also known as Shielded Metal Arc Welding (SMAW), is a manual welding process that uses an electrode (stick) coated in flux to create the weld. The flux coating melts during the welding process, creating a protective gas shield and producing a slag that covers the weld bead, protecting it from contamination.

How does stick welding work?

Stick welding works by creating an electric arc between the electrode and the workpiece. The electrode, which is connected to the positive terminal of the welding machine, provides the filler metal and flux, while the workpiece serves as the grounding point. As the electrode is introduced to the workpiece, an arc is generated, melting the electrode and creating a weld pool that solidifies into the desired joint.

Advantages of stick welding

Stick welding is popular for its simplicity and versatility. It can be performed in various positions, making it suitable for welding in different environments and on different materials. Stick welding is also more forgiving in terms of surface preparation and can be used outdoors, even in windy conditions. Additionally, stick welding equipment is relatively inexpensive and portable.

Disadvantages of stick welding

One of the main disadvantages of stick welding is its lower deposition rate compared to other welding methods. It also produces more spatter and slag, requiring more post-weld cleaning. Stick welding can be more challenging for beginners due to the need for precise electrode manipulation and maintaining a consistent arc length.

What is stick welding used for?

Stick welding is commonly used in construction, maintenance, and repair projects. It is suitable for welding thick materials, including carbon steel, stainless steel, and cast iron. Stick welding is often used in outdoor applications, such as pipeline welding and structural steel fabrication.

Does stick welding require gas?

No, stick welding does not require a shielding gas as the flux coating on the electrode provides the necessary protection. This makes stick welding a convenient option for situations where a shielding gas may not be readily available.

How MIG Welding Works

MIG welding, also known as Gas Metal Arc Welding (GMAW), is a semi-automatic welding process that uses a continuously fed wire electrode and a shielding gas to create the weld. The wire electrode is consumed during the welding process, providing both the filler metal and the electrode.

Is MIG welding AC or DC?

MIG welding can be performed using either AC (Alternating Current) or DC (Direct Current). AC is commonly used for aluminum welding, while DC is preferred for steel and stainless steel welding.

Advantages of MIG welding

MIG welding offers higher deposition rates and faster welding speeds compared to stick welding. It also produces cleaner welds with less spatter and slag, requiring minimal post-weld cleaning. MIG welding is relatively easy to learn and provides excellent control over the welding process, making it suitable for both beginners and experienced welders.

Disadvantages of MIG welding

MIG welding requires a shielding gas to protect the weld from atmospheric contamination. This means that a supply of shielding gas, such as argon or a mixture of argon and carbon dioxide, is necessary. MIG welding equipment can be more expensive than stick welding equipment, and the process is less forgiving when it comes to welding in windy conditions or on dirty surfaces.

What is MIG welding used for?

MIG welding is widely used in manufacturing, automotive, and fabrication industries. It is suitable for welding thin to medium-thickness materials, including carbon steel, stainless steel, aluminum, and various alloys. MIG welding is commonly used for automotive body repairs, sheet metal fabrication, and structural welding.

Can you MIG weld without gas?

Yes, it is possible to MIG weld without gas using a process called flux-cored arc welding (FCAW). Flux-cored wire electrodes contain a flux compound that provides the necessary shielding when it melts during the welding process. This makes flux-cored MIG welding a versatile option for outdoor applications or situations where a shielding gas may not be available.
