How do you read electrode codes?
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 you classify an electrode?
The welding electrodes are classified on the basis of the electrode metal, flux coating, current used, position of welding, performance characteristics, chemistry and the mechanical properties of the weld metal etc.
What is the meaning of E6013 E6010 e6011 and E7018?
E6012 = High titania sodium flux. AC or DCEN for flat, vertical, overhead, and horizontal positions. E6013 = High titania potassium flux. AC, DCEP, or DCEN for flat, vertical, overhead, and horizontal positions. E7018 = low-hydrogen potassium, iron powder flux.
What is the meaning of electrode E7018?
E7018 is a low-hydrogen iron powder type electrode that produces high quality x-ray welds. It can be used in all positions on AC or DC reverse polarity welding current.
What does the 70 in 7018 mean?
For example, the number 70 in a E7018 electrode indicates that the electrode will produce a weld bead with a minimum tensile strength of 70,000 psi. The third digit represents the welding position(s) for which the electrode can be used.
What does B2 mean in welding?
E8018-B2 welding electrode is for higher strength steels with tensile strengths greater than 80,000 pounds. The coating is specially formulated to resist moisture pick-up under conditions of high heat and humidity.
What does the 8 stand for in 7018?
8 – the '8' indicates that the rod has low hydrogen potassium with iron powder coating and that it can be used with all polarities (DC+, DC-, or AC). The final number, '8' in the case of our E7018 rod, requires more explanation.
What is the meaning of E in E6013?
E6013 is characterized as follows: E stands for electrode. 60 stands for tensile strength which is almost 60,000 pounds per inch. 1 stands for position of electrode. This welding rod can be used for all four positions – flat, horizontal, vertical and overhead.
When to use 6010 or 7018?
E 6010 electrode can be used on painted, galvanized, and unclean surfaces, while E 7018 is used on clean or new sheet metal. E6010 is used for deep penetration welding, while E 7018 is used for welding metal that tends to crack, producing quality welds with excellent toughness and high ductility.
What does ER70S 2 mean?
Pinnacle Alloys ER70S-2 is a copper-coated solid wire designed for welding carbon and carbon-manganese steels with tensile strength up to 73,970 psi (510 MPa).
What does H4 mean in E7018 H4R?
For example, H4 indicates that the product has 4 ml or less of diffusible hydrogen per 100 g of weldment. Similarly, the H8 designator indicates that the stick electrode has 8 ml or less of diffusible hydrogen per 100 g of weldment. Some E7018 stick electrodes will have an additional “R” designator (e.g., E7018 H4R).
What does 6010 mean?
6010 and 6011 Electrodes 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.
