Hey there! I’m a supplier of hot rolled steel plates, and I often get asked the question, "Can hot rolled steel plates be welded?" Well, the short answer is yes, they can. But there’s a bit more to it than that, so let me break it down for you. Hot Rolled Steel Plates<\/a><\/p>\n

<\/p>\n

First off, let’s talk a bit about hot rolled steel plates. These are steel plates that are made by heating steel above its recrystallization temperature and then rolling it into the desired thickness. This process gives the steel a rough surface finish and often some scale on the outside. The advantage of hot rolling is that it’s a cost – effective way to produce large quantities of steel plates, and it also improves the ductility and workability of the steel.<\/p>\n

Now, when it comes to welding hot rolled steel plates, the good news is that most common types of hot rolled steel are weldable. Carbon steel, which is a major type of steel used in hot rolled plates, has good weldability characteristics. The key factor that affects weldability is the carbon equivalent of the steel. The carbon equivalent is a calculation that takes into account the amount of carbon and other alloying elements in the steel that can influence how it behaves during welding.<\/p>\n

For general carbon hot rolled steel plates, if the carbon equivalent is within an acceptable range (usually up to about 0.4 – 0.5%), the steel can be welded using conventional welding methods without too many issues. Some of the common welding methods for hot rolled steel plates include shielded metal arc welding (SMAW), gas metal arc welding (GMAW), and flux – cored arc welding (FCAW).<\/p>\n

Let’s take a closer look at these welding methods:<\/p>\n

Shielded Metal Arc Welding (SMAW)<\/h3>\n

This is one of the oldest and most widely used welding methods. It uses a consumable electrode that is coated with a flux. When the electrode is struck against the steel, an arc is created, which melts the electrode and the base metal. The flux on the electrode creates a protective gas shield around the weld pool, preventing oxidation and other contaminants from getting into the weld. SMAW is a great option for welding hot rolled steel plates, especially in outdoor or field conditions. It’s relatively easy to learn and can be used to weld a variety of thicknesses of steel plates.<\/p>\n

Gas Metal Arc Welding (GMAW)<\/h3>\n

Also known as MIG (metal inert gas) welding, GMAW uses a continuous solid wire electrode that is fed through a welding gun. A shielding gas, such as argon or a mixture of argon and carbon dioxide, is used to protect the weld pool from oxidation. GMAW is a very efficient welding method and can produce high – quality welds quickly. It’s suitable for welding hot rolled steel plates in a shop environment where a stable power supply and proper ventilation are available.<\/p>\n

Flux – Cored Arc Welding (FCAW)<\/h3>\n

This method is similar to GMAW, but instead of a solid wire electrode, it uses a tubular wire filled with flux. The flux in the wire provides the shielding gas, so in some cases, an external shielding gas may not be required. FCAW is a good option for welding thicker hot rolled steel plates, as it can penetrate deeper into the base metal compared to some other welding methods.<\/p>\n

However, there are a few things to keep in mind when welding hot rolled steel plates. One of the main issues is the scale on the surface of the steel. The scale can cause porosity in the weld, which can weaken the joint. So, before welding, it’s important to clean the surface of the steel plates. You can use a wire brush, grinder, or chemical treatment to remove the scale and any other contaminants.<\/p>\n

Another thing to consider is pre – heating and post – heating. Depending on the thickness of the steel plates and the carbon equivalent, pre – heating the steel before welding can help reduce the risk of cracking. Pre – heating can slow down the cooling rate of the weld, which can prevent the formation of hard and brittle microstructures. Post – heating, or stress – relieving heat treatment, can also be done after welding to reduce the internal stresses in the weld and the surrounding base metal.<\/p>\n

Now, let’s talk about some of the challenges that you might face when welding hot rolled steel plates. Sometimes, if the welding parameters are not set correctly, you can end up with problems like lack of fusion, where the weld metal does not properly bond with the base metal, or excessive spatter, which can make the weld look messy and also waste welding material.<\/p>\n

To avoid these problems, it’s important to follow the manufacturer’s recommendations for welding the specific type of hot rolled steel plates you are using. You should also make sure that your welding equipment is in good working condition and that you have the right welding consumables.<\/p>\n
