Frequently Asked Questions
What is the main application of E309-16 welding electrodes?
E309-16 is primarily used for welding corrosion-resistant stainless steel structures (such as SUS304) where the working temperature is below 300ºC, and it is also ideal for welding dissimilar steels.
Do these electrodes require pre-heating?
Yes, for optimal results, electrodes should be re-dried at 320ºC-350ºC for about 1 hour before use to ensure they are moisture-free.
Can I use these welding rods with AC power?
Yes, these electrodes are compatible with both AC and DC power, though DC+ is generally suggested for better performance and stability.
What are the available diameters for these welding rods?
The standard diameters range from 2.0mm to 5.0mm, with lengths typically between 300mm and 400mm depending on the specification.
What is the significance of the "L" in models like E308L or E316L?
The "L" stands for "Low Carbon," which provides extra resistance to intergranular corrosion after welding.
What is the monthly production capacity for these products?
The production facility has a capacity of approximately 1000 tons per month to ensure steady supply.
