You need a welding rod of the most appropriate size and specifications to obtain favorable results. If you don’t understand the procedure to select the right rod, this article will help. A welding rod melts and aids fusion of two materials during the process of welding. There are different types of electrodes like 6011, 6012, 7014, 7018 etc. Each digit in the welding rods sold by welding electrodes manufacturers and suppliers indicate specific properties.
How to Choose a Welding Rod?
Discuss your requirements with welding electrodes suppliers and consider the below mentioned tips before proceeding with the purchase.
Tensile Strength
Take your base metal and check if the minimum tensile strength of the electrode matches that of the base metal. How do you figure out the tensile strength of the welding rod? While you can clarify it from the welding electrodes manufacturers, you can check the digits printed on the welding rod. If the number 6011 is imprinted on the rod, you can conclude that it has a strength of 60 pounds per square inch. The base metal should be also of the same strength failing which it may negatively impact the weld quality.
Base Metal Properties
Take into account the properties of the base metal and zero in on the most suitable electrode. Thickness, shape and joint fit-up are some of the factors to be considered. If your welding project involves thick metal, you need an electrode characterized by high ductility and low hydrogen content. If the number on the electrode ends with 15,16 or 18, you can safely pick one of those to be used with thick materials. Welding electrodes suppliers in India have those numbered as 6013 for use with thinner materials.
Weld Position
Know the weld position by checking the number. To understand the compatibility of electrodes with welding positions, you need to pay attention to the third digit. If you spot 1 as the third digit, it suggests compatibility with all the welding positions. If you see number 2, the compatibility is limited to only flat and horizontal positions. Choose one of the expert welding electrodes manufacturers in India who can guide you with valuable information on picking the right wedding rod.
Polarity
The direction of current is referred to as polarity. There are two types of polarity - straight and reverse. The former works by pushing electrons toward the object. This is because the positive workpiece attracts the electrons as the electrode is negative. In the latter type of polarity, the exact opposite happens. Electrons are attracted to the electrode because it is positive and the workpiece is negative. Shortlist few welding electrodes manufactures and suppliers that have electrodes that work with both alternating current and direct current.
Condition of Metal
What kind of metal do you have? You need different electrodes for clean and smooth metals and rusty metals. You don’t want to make the mistake of buying a wrong electrode to later realize that it doesn’t suit the metal in your hand. Here is a quick tip. If you have a clean metal, go for 6013 electrodes. If not, go for 6010 and 6011 electrodes. For detailed information, try contacting one of the reputed welding electrodes suppliers in India.
