What is UTP welding rod:

The electrode is a coated metal wire. It is made of materials similar to the metal being welded. Firstly, there are consumable and non consumable electrodes. In shielded metal arc welding (SMAW), also known as welding rods, the electrodes are consumables, which means that the electrodes will be consumed and melted with the weld during use. In tungsten inert gas welding (TIG), electrodes are non consumables, so they do not melt and become part of the weld seam. In gas shielded arc welding (GMAW) or MIG welding, the electrodes are continuously fed with wire. Flux cored wire arc welding requires a consumable tubular electrode containing a continuous supply of flux.

How to select welding rods:

The selection of welding rods depends on the requirements of the welding work. These include:

• Tensile strength

• Ductility

• Corrosion resistance

• Base metals

• Welding position

• Polarity

• Current

There are light coated electrodes and heavy coated electrodes. Light coated electrodes have a light coating that can be applied by brushing, spraying, soaking, washing, wiping, or rolling. Thick coated electrodes are coated by extrusion or drop coating. Heavy coatings are mainly divided into three types: minerals, cellulose, or a combination of both. Heavy coating is used for welding cast iron, steel, and hard surfaces.

What do the numbers and letters on the welding rod mean

The American Welding Society (AWS) has a numbering system that provides information about specific electrodes, such as what applications they are most suitable for and how they should be operated to achieve maximum efficiency.

Digital coating type welding current

0 high cellulose sodium direct current+

1. High cellulose potassium AC, DC+or DC-

2 Sodium Titanate AM, DC-

3. High potassium titanium dioxide AC and DC+

4 iron powder, titanium dioxide AC, DC+or DC-

5 Low hydrogen sodium direct current+

6. Low hydrogen potassium AC and DC+

7. High iron oxide, potassium powder AC, DC+or DC-

8. Low hydrogen potassium iron powder AC, DC+or DC-

'E' represents the arc welding electrode. The first two digits of the four digits and the first three digits of the five digits represent the tensile strength. For example, E6010 represents a tensile strength of 60000 pounds per square inch (PSI), and E10018 represents a tensile strength of 100000 psi. The penultimate number represents the position. Therefore, "1" represents the full position electrode, "2" represents the planar and horizontal electrodes, and "4" represents the planar, horizontal, vertical downward, and top electrodes. The last two digits specify the coating type and welding current.
