How to identify welding rod numbering system

Welding is a very important process to join metal bodies. Moreover, the Welding rod is the key element of this process. Many variant welding rods are available in the local market. However, the welding rod is selected based on metal type, strength and process. A welder can easily identify necessary information from the welding numbering system printed on the welding rod surface. Many people tell it also welding rod specification. This welding rod specification is determined by the international organisation. Thus, any entrepreneur can establish a welding rod manufacturing plant, but they must ensure the welding rod numbering procedure. Moreover, the Quality of the electrode depends on raw materials and processing of production. Some reputed companies make quality full welding rods, so welders can easily make wonderful welding joints within a short time. For this reason, better quality welding rods have huge demand all over the world. By the way, the electrode is a consumable item. Therefore, Hundreds of companies make plenty of welding rods every day. Among all companies, Linde is one of the leading welding rod manufacturer internationally. They have many production plants in various countries. The welding process is very useful in any type of metal fabrication-related work. In this process, the welding rod works as the main filler metal. It has some additional benefits to bring the necessary strength in joining area. Basically, the welding process is applicable for metal fabrication, machine manufacturing, sheet metal-related work etc. There are various types of welding rod numbering systems.

As per AWS A5.1 Carbon steel electrodes *(Welding rod numbering system)

E 60 1 4

E- means Electrode for arc welding

60- minimum tensile strength in ksi, so 60,000 pound per square inch

1– means position all position, 0 means no classification used, 2 for flat and horizontal both position of welding, 3 means flat position welding only

4- this number indicates type of power supply and coating

Last number indication

0 – high cellulose sodium  DC + current

1- high cellulose potassium AC,DC +-

2- high titania sodium AC,DC-

3- high titania potassium AC,DC+-

4- Iron power titania AC,DC+-

5- low hydrogen sodium DC+

6- low hydrogen potassium AC,DC+

7-high iron oxide , iron powder AC,DC+-

8- low hydrogen potassium, iron powder AC,DC +-
