Welding Rods 6011
Products Description
E6011 is a high-cellulose sodium type electrode designed and produced according to AWS A5.1 standard. Its coating contains 30%-40% cellulose. During welding, the coating can decompose to produce a mixed gas of CO₂+H₂ to form a protective atmosphere, which has a good protection effect on the molten pool and can effectively suppress welding defects such as pores and slag inclusions.
This electrode is suitable for welding low-carbon structural steel, ordinary carbon steel, and low-carbon steel components with thick rust or oxide layers. It performs well in all-position welding and is especially suitable for welding stress-bearing structures with high requirements for weld density.
Product Advantages
Excellent welding processability
- High arc stiffness: The arc column concentration rating reaches Class A, and the penetration control of ≤6mm can be achieved in the overhead welding position. The weld bead forming coefficient is stable at 1.3-1.5. The arc column is not easy to diverge during welding and is easy to control.
- Suitable slag fluidity: The coating basicity coefficient (B1) is between 0.8-1.0, the slag solidification speed is moderate, and the molten pool can be controlled by adjusting the current during vertical welding to ensure the quality of weld bead forming.
- Low spatter rate: According to the GB/T 10045 standard test, the spatter rate is ≤5%, which is significantly lower than the average level of 8-12% of similar electrodes, reducing the cleaning work after welding.
Wide range of applications
Application data from a welding workshop of a heavy machinery factory shows that when using E6011 welding rods to weld rusted engineering machinery structural parts, compared with conventional welding rods, two surface treatment processes are reduced, the welding cycle of a single workpiece is shortened by 25%, and the first-time pass rate of welds is increased to 98.6%, which is much higher than the industry average of 89.3%. This means that while improving welding quality, production efficiency can be improved and production costs can be reduced.

FAQ
Q: What are the precautions for storing E6011 welding rods?
A: They should be stored in an environment with a temperature of 15-30℃ and a relative humidity of ≤60%, and should be kept away from corrosive media. The shelf life in the original sealed packaging is 6 months (from the date of production). If the welding rod absorbs moisture, it must be dried at 80-100℃×1-2h before use, but the temperature is strictly prohibited to exceed 120℃ to prevent the coating from becoming brittle. The dried welding rod should be stored in an 80-100℃ welding rod insulation cylinder for no more than 4h.
Q: What are the packaging specifications of E6011 welding rods?
A: The packaging specifications are 5kg/Inner box, 20Kg/Carton, and 1000kgs/Pallet. Each box will be accompanied by a material certificate, including the furnace number, mechanical properties test report, coating composition analysis, etc. The entire production process can be traced through the batch number.
Q: What are the payment and production delivery regulations for ordering E6011 welding rods?
A: In terms of payment, 30% TT prepayment and 70% TT before delivery are adopted. In terms of production and delivery, the regular production capacity is 300 tons per month, which can meet the continuous supply of batch orders, and the Production Time is Within 25days after recerving prepayment. In addition, paying a 20% expedited fee can shorten the delivery cycle by 30% (the raw material inventory needs to be confirmed).
Q: What specifications are available for E6011 welding rods?
A: Specifications with diameters of 2.5mm, 3.2mm, 4.0mm, and 5.0mm are available, and customized models can be produced according to EN 499 standards.
