What is Weathering Steel in Welding?

Weathering steel is a low alloy steel that is specially formulated to form a thin, tightly adhering layer of rust. This initial layer prevents further rusting and thus, the need to paint the steel is eliminated. The main alloys in this steel are copper and chromium.

Where is weathering steel used?

Weathering steel is commonly used in welding applications because it does not require pre or post-weld heat treatment. This means that it can be welded without affecting the properties of the steel. Weathering steel is also highly resistant to corrosion, making it an ideal choice for welding applications in harsh environments.

Can weathering steel be welded?

Yes, weathering steel can be welded.

What grade of steel is weathering steel?

The most common grade of weathering steel is A242. Other grades that are sometimes used include A588, A606, and A847. These grades have different compositions and mechanical properties, but they all exhibit superior corrosion resistance compared to traditional carbon steels.

What are the advantages of using weathering steel?

There are several advantages to using weathering steel in welding applications:

  1. First, it eliminates the need for painting, which can save time and money.
  2. Second, it is highly resistant to corrosion, so it can be used in environments that would normally require the use of stainless steel or other more exotic materials.
  3. Finally, weathering steel has good weldability properties, making it easy to weld without affecting the steel’s properties.

Corten welding wire

For welding weathering steel, we recommend using a Corten welding wire. This wire is specifically designed for welding weathering steel and will produce less spatter and provide better weld penetration than other types of welding wire.
