How do you read a welding rod code?
Welding Current The first two digits of a 4-digit number and the first three digits of a 5-digit number stand for tensile strength. For example, E6010 means 60,000 pounds per square inch (PSI) tensile strength and E10018 means 100,000 psi tensile strength. The next to last digit indicates position.
How do I identify a welding rod?
The welding rod electrode identification system for stainless steel arc welding is set up as follows:
- E indicates electrode for arc welding.
- The first three digits indicated the American Iron and Steel-type of stainless steel.
- The last two digits indicate the current and position used.
What do the 4 digit codes mean on the electrode?
For example, 1 means the electrode can be used in all positions and 2 means it can be used on flat and horizontal fillet welds only. The fourth digit represents the coating type and the type of welding current (AC, DC or both) that can be used with the electrode.
What is the number on the welding rod?
The number 1 indicates that you can weld in any position, while a 2 indicates that you must use the rod in a horizontal position. The number 4 indicates the rod can be used in a vertical position. The final number in the sequence tells you the coating of the rod and the current you can use with the electrode.
What does the numbers on a 7018 welding rod mean?
The 7018 Welding Rod The “E” in E7018 electrode indicates a tool used for an arc-welding process. The 70 means it makes welds that are very strong (70,000 psi). The 18 means two things: The “1” means the electrode can be used in any position, and the “18” means low hydrogen and usually DC current.
What is the range of normal electrode size?
Selection of Correct Size of Electrode However commonly available electrode sizes are 2.0 mm, 2.5 mm, 3.2 mm, 4.0 mm and 5.0 mm. For special applications we have different size electrodes also. Some manufacturers use slightly different sizes like 3.15 mm for 3.2mm and 2.4 mm for 2.5 mm etc.
What does 5P welding rod mean?
A 5P welding rod is also known as an E6010 rod. It consists of an all-purpose filler metal designed for use with direct current (DC) and suitable for welding pipes.
What does 6010 welding rod mean?
The “60” in 6010 means 60,000 pounds’ tensile strength (the ability to resist being pulled apart) per square inch. The “1” means it can be run in any position—flat, horizontal, vertical, or overhead.
What do the numbers 7018 mean on a welding rod?
What is a 6011 welding rod used for?
E 6011 electrode is a general-purpose electrode performs welding in all positions and efficiently in vertical-up and over-head positions; it is used mainly for sheet metal welding and low silicon deposit application. The electrode arc is easy to control and produces a flat weld bead with light slag formation.
What are 1/16 welding rods used for?
This 1/16 in. AWS E6013 electrode is an all-purpose welding rod with good penetration and fast deposition rates. Other benefits include low spatter and easy slag removal. This outstanding welding rod is ideal for general welding applications around the shop or garage.
What is the ‘a’ number in welding rods?
The A Number: Another type of grouping for filler metal or welding rod is the ‘A’ Number. ‘A’ number grouping has been done on the basis of the chemical composition of the deposited weld metal.
What is an f number used for in welding?
Filler Metals: The F Number. This number is used to group filler metals used in welding procedures and welder performance qualifications. The definition of F-Numbers is provided in QW-431 of ASME IX:
What does the ‘E’ mean on a welding rod?
The ‘E’ entails the arc welding electrode. If the welding rod comes with 4-digits, then the first two numbers stand for tensile strength; if it has 5-digits, then the first three will be for the tensile strength. An example of this will be – E7018 stands for 70,000 pounds per square inch (PSI) tensile strength.
What is the P-number for e9018-b3?
E9018-B3 is F-No. 4 and A-No. 4. 2.25Cr1Mo base metal is assigned P-No. 5A. The 300 series stainless steel base metals are assigned P-No. 8.
