There are many welding consumables available in the country where you can find many places to buy them. Typically welding consumables are available in any local hardware shop, but finding quality welding consumables is difficult without any proper knowledge.
To know more about different types of welding electrodes and welding wire some information is given below:
Welding electrodes are also known as the welding rod which is generally used in shielded metal arc welding process or arc welding process. It is necessary to ensure that the welding rod is built according to the American welding standards (AWS) code.
Welding wires are generally used for the Gas welding process, TIG welding process, SAW welding process, etc. These welding wires are also built according to the AWS code, if not then it can ruin the weld as well as the parent metal.
To choose the Welding Rod, a welder should identify which welding process is required, which type of metal is there, etc.
Let’s discuss some of the best welding rods in India:
Norma: It is a medium coated rutile type AC/DC all position mild steel welding rod to weld mild steel structures, rail coaches, wagons, storage tanks, ships, sheet metal work, etc.
Norma is one the most common mild steel welding electrodes which are designed according to the AWS- E6013.
Supratherme– It is an E7018 welding electrode that is a coating of low hydrogen and iron powder. This type of electrode is an ideal suit for producing tough and ductile welds of X-Ray quality over boilers, heavy structures & pressure vessels which are subjected to dynamic loading. This E7018 welding rod has a metal recovery of about 115%. Some of its typical application includes heavy structures subjected to dynamic loading and impact, highly restrained joints, earthmoving machines, etc.
Medio: This welding rod is a medium coated rutile type Mild Steel Welding Electrode that is designed to operate even with 45 OCV. It is suitable for all types of mild steel structures for plant machinery, pipes, trawlers, etc. The weld metal obtained is soft and ductile. This particular E6013 welding rod or Mild Steel welding electrode gives quality weld.
NFM: It is a welding rod that deposits a very high nickel weld metal for welding cast irons components. This particular rod deposits a soft and has good resistance to cracking. It is an ideal suit for welding cast iron to produce a good machinable weld deposit. It is also well suitable for repairing cracks filling up and various surfacing applications.
Fenitherme: It is a very special Ferro -Nickel-based welding electrode that is designed for repairing welds and for joining various components of different types of cast irons, including grey and nodular cast irons, and for welding them to steel and some ferrous and non-ferrous materials. This particular electrode is an ideal suit for rectification of defective casting in cast iron foundry and a variety of cast iron machine parts and equipment. Fenitherme is suitable for welding cast iron to steel and some ferrous and non-ferrous materials.
