Welding is an integral part of the construction and manufacturing process. It can be used to create a strong bond between different metals, with hundreds of different steel welding rods available for a variety of purposes. But of all the welding rods available, which one is the strongest?
In terms of sheer strength, the answer is the aptly-named ‘super rod,’ which can weld together even the heaviest of materials with tensile strength of over 200,000 psi. It can even weld together two pieces of steel at temperatures up to 2,500° F!
Statistics show that up to a quarter of all welding rods used in the US are ‘super rods’, making them particularly popular among welders. In this article, we’ll take a look at what the strongest welding rod is, how it works and why it’s ideal for certain welding applications.
What is the Strongest Welding Rod?Welding is a process used to join two metal components together.
Welding rods, also known as filler metals, are used to create strong and durable welds. Knowing the right type of welding rod to use is critical when it comes to achieving a successful weld. So, what is the strongest welding rod?
Types Of Welding RodsThe most common type of welding rod is the stick welding rod, or SMAW (Shielded Metal Arc Welding). There are different types of welding rods based on their composition, such as:
- Carbon Steel – Primarily used for unalloyed or low-alloyed steel structures.
- Stainless Steel – Used on alloys with higher strength, corrosion and temperatures.
- Nickel Alloys – Used on components exposed to high-temperatures and corrosion.
- Aluminum – Used on components that need higher strength.
The Strongest Welding RodThe strongest welding rod would depend on the application and the metal being welded. For general purpose welding, the 6011 welding rod is considered the strongest.
It has the deepest penetration, best arc stability and most flexibility of any arc welding rod. The 6011 welding rod is also the most popular and commonly used welding rod. For stainless steel welding, the strongest welding rod is the 308L series.
It is designed for welding materials such as 304 and 304L stainless steel. 308L welding rods are designed to have low hydrogen and have great resistance to corrosion.
