Sub-Merged Arc Welding Wire: Types, Uses, & Maintenance
This article discusses different types of wire used in Sub-Merged Arc Welding Wire (SMAW), its applications, maintenance, and many more.
What is Sub-Merged Arc Welding Wire?Sub-merged arc welding wire is used to join two pieces of metal together. This type of welding wire is made up of several strands that are held together by a coating. Submerged arc welding wires are usually less expensive than other types of welding wire, and they are also easier to work with.
There are several applications for sub merged arc welding wire. This type of welding wire can join pieces of metal together during construction projects. It can also be used to repair broken pieces of metal. Finally, sub merged arc welding wire can be used to weld small parts together.
The main downside to using sub merged arc welding wire is that it is not as strong as other types of welding wire. Additionally, sub merged arc welding wires can be damaged if they are not properly maintained.
Types of Sub-Merged Arc Welding WireThe types of welding wire used for submerged arc welding (SMAW) depend on the application. The most common types are gas shielded,arc-contained, and gas tungsten electrodes. Each has its benefits and drawbacks.
Arc-Containored Welding Wire: Arc-contained welding wire is made of several strands that are twisted together to form a conductor. This type of wire is best for gas-shielded electrodes because the gas cant reach the weld.
Gas Tungsten Electrode Welding Wire: A gas tungsten electrode welding wire is made of a single strand of metal thats heated until it becomes soft. This type of wire is perfect for gas-shielded or arc-contained electrodes because it offers more heat and better penetration than other welding wires.
Gas Shielded Welding Wire: The welding wire contains tiny holes that trap the gas from the arc and protect the weld area from contaminants and heat. This type of wire is best for arc-contained electrodes because they dont need as much heat to start the weld.

How do I find the size of the Sub-Merged Arc Welding that I need?When welding with a sub-merged arc welder, its essential to have the correct wire size. The wrong size wire can cause poor welds and even shorts.
Here are some tips for finding the right size wire for your sub-merged arc welder:
- Measure the diameter of the welding rod youll be using. This will give you a starting point for choosing a wire size compatible with that rod.
- Remember that the smaller the diameter of your wire, the more heat it will produce. So if you need to weld thick pieces of metal, choose a thicker wire size.
- Choose a wire size thats comfortable to hold and pass through your welders spool gun. Too-thin wires can break easily, while too-thick wires can cause problems with your welders spool gun.
- If you need to weld delicate materials or under challenging positions, choose a thin wire size. Sub-merged arc welding is less forgiving than gas tungsten arc welding when it comes to mistakes made during welding.
Sub-Merged Arc Welding wire is a type of welding wire made up of smaller diameter wires that are welded together to form a continuous wire.
This type of welding wire is used for applications where the size or shape of the weld cannot be achieved using other types of welding wires. Sub-Merged Arc Welding wire is also known as micro weld welding wire because it is used to make tiny welds.
Sub-Merged Arc Welding wire is most commonly used in welding metal to metal, but it can also be used to weld metal to plastic, metal to glass, and other materials.
Sub-Merged Arc Welding wire has many benefits over other types of welding wire. These include:
- Sub-Merged Arc Welding wire is easier to work with because it is smaller in size and shape.
- Sub-Merged Arc Welding wire can be used in more difficult positions than other types of welding wires.
- Sub-Merged Arc Welding wire produces a cleaner weld than traditional welding wire.
Yes, the sub-merged arc welding wire is typically made of a specific alloy and is designed for use with certain types of metals. In addition, its essential to keep sub-merged arc welding wire in good condition to perform its intended function.
What is the most common wire size for a Sub-Merged Arc Welding wire?The most common wire size for a Sub-Merged Arc Welding wire is .018 inches. This size wire is used in many applications, such as welding aluminum, stainless steel, and other metals.
What is Submerged Arc Welding (SAW)?
Submerged Arc Welding (SAW) is a joining process that involves the formation of an electric arc between a continuously fed electrode and the workpiece to be welded. A blanket of powdered flux surrounds and covers the arc and, when molten, provides electrical conduction between the metal to be joined and the electrode. It also generates a protective gas shield and a slag, all of which protects the weld zone.
The make-up of the process can be viewed by reference to Figure 1 below
Figure 1. The Submerged Arc Welding Process
As can be seen from Figure 1, the arc is "submerged" beneath a blanket of flux and is, therefore, not usually visible during the welding operation itself. These facts make the process advantageous from a health and safety viewpoint as there is no arc to promote "arc eye" and very little fume.
There are two welding consumables involved in the process, the electrode and the flux. The electrode can be a solid wire, a cored wire, or a strip. The flux, made from a variety of minerals and compounds, can be rather complex and can be produced in a number of forms.
The general arrangement of the power source and controls, wire feed and flux dispensing are shown in Figure 2.
Figure 2. General Arrangement of the Submerged Arc Process
Submerged arc welding is viewed as a high productivity process and is usually automated/mechanized in its form. The simplest application of the process uses a single wire.
Selecting the correct wire diameter for a welded joint depends on many factors and the size of the available power source usually limits the diameter of the wire that can be used. While most power sources for this process are 1,000 amps, smaller power source may be used. A 3/32-in.-dia. wire through to a 5/32-in.-dia. wire will run in the 300 to 900 amps range using direct current and with the electrode positive (DC+)
This welding process is typically suited to the longitudinal and circumferential butt welds required in the manufacture of pressure vessels and for joining plating and stiffeners in shipyards. Welding is positionally restricted and is normally carried out in the flat or horizontal positions because of the highly fluid weld pool, the molten slag, and the need to maintain a flux covering over the arc.
As with all welding processes the selection of the consumables (wire and flux) and other parameters such as amps, volts and travel speed are intended to give a weld deposit that satisfies the objectives of the designer. In the case of this welding process, since the arc is submerged, the welding operator cannot see the molten weld pool and must, therefore, very accurately set the welding parameters and location of the welding nozzle within the joint.
Submerged arc welding has many advantages but there are also restrictions, some of these are listed below
Advantages
- High deposition rates and high arc on times when fully automated.
- Minimal welding fume, no weld spatter and no visible arc
- Unused flux can be recovered
- If metallurgically acceptable, single pass welds can be made in relatively thick plates.
Restrictions
- Limited to steels, although some consumables have been developed for other materials such as nickel-based alloys.
- Cannot be used in the vertical or overhead welding positions. Used principally for butt welds in the flat position (1G) and fillet welds in the flat and horizontal position (1F & 2F). Horizontal butt welds can be made but special devices are required to support the flux.
- Requires separate flux handling systems and slag removal between passes.
- Not realistically applicable to thin materials.
There are many more applications of this welding process, other than its use with a single wire, and the fluxes used can be quite complex in their design and production. These items may be covered in later articles.
