Can you weld rolled steel
When it comes to metal rolling and welding, steel is one of the most common materials that is custom rolled. Hot rolled steel is often preferred because it tends to be cheaper than cold rolled steel. A big question people pose is, “Can hot rolled steel be welded?” The simple answer is, “Yes.” Actually both types of steel can be welded, though cold rolled steel is often harder because it is smoother and welding it can discolor it if you’re not careful. Also, what makes welding either types of steel difficult is mill scale. This is the oxide layer that forms over the steel when fabricated. The mill scale can slow the flow of the weld pool creating poor appearances or contours.
Some ways to make welding rolled steel a bit easier include:
- Slowing the travel speed, though this will slow down production and may not be an ideal option.
- Use gas-shielded welding processes.
- The best gas-shielded process is metal arc welding using solid wire.
- The next best route is gas-shielded metal arc welding using metal-cored wire.
- The final option is using flux-cored arc welding with gas-shielded wire.

What is difference between hot rolled and cold rolled steel?
When you’re weighing between welding cold rolled vs hot rolled steel you need to know what the difference between the two types of steel are. The primary difference between the two is the fabrication process between the two. As the name implies, hot rolled steel is fabricated using heat. It is pressed at temperatures over 1,700 degrees. On the other hand, cold rolled steel is pressed at or near room temperature. Cold rolled steel will be shiny and smooth and often hardened by the fabrication process. This makes it a little more difficult to weld because it’s easier to cause discoloration than with hot rolled steel. Hot rolled steel is a little softer and the welds will be less apparent. If you are looking for metal rolling and welding services, you can count on the team at Haltom Industries.
Welding rolled metal
With metal rolling and welding, some metals are better than others. While hot rolled and cold rolled steel are often difficult to weld, other materials are very reliable. Some metals like low carbon mild steel, aluminum and stainless steel require the fewest pre- and post-weld operations, so the weld is less likely to fail. Of these low carbon mild steel is one of the best to use. It is commonly used so it is abundant, and current welding technology and techniques are easily adapted to its use. It’s also more ductile than other types of steel.
Welding cold rolled steel to stainless
Metal rolling and welding can create several complications, especially if you are trying to combine two different types of materials like cold rolled steel and stainless steel. Sometimes dissimilar materials have to be used for cost considerations or service condition requirements. Often combining different materials can be more economical than building with just one material. This often occurs in power generation facilities as well as in mining operations. Whenever you’re welding different types of materials together you’ll want to select the right filler materials and use proper welding techniques. Matching the filler material is critical. It has to be chemically compatible with both materials for a solid, lasting weld.
Is hot rolled or cold rolled steel easier to bend?
Because of the processes in which these types of steel are fabricated, they have various levels of hardness. Cold rolled steel, fabricated near or at room temperature, is harder than hot rolled steel, and thus less easy to bend and shape. Metal rolling and welding applications may be limited with cold rolled steel. On the other hand, cold steel is easier to craft to exact specifications, and works best in applications where strength is more important than flexibility.
Does cold rolled steel rust?
While cold rolled steel can corrode and rust when being shipped or warehoused, most manufacturers finish it out with oil. These oils are specially designed as rust-inhibitors. Along with oil, rust can be prevented by storing the steel in dry, climate-controlled environments.
Why is cold rolled steel more expensive?
Even though cold rolled steel has many advantages over hot rolled steel, especially when it comes to toughness, it is normally more expensive. Much of the expensive is due to the manufacturing process itself. The metal is harder to manipulate and takes more time to fabricate than hot rolled steel, so it costs more to process. The difficulty of manipulating cold rolled steel also tends to cause projects using it to take more time, and this can make the projects more expensive.
