Hot Rolled Steel & Cold Rolled Steel - Difference &

May 22, 2019 · Thus, the yield strength of cold rolled steel is higher than that of hot rolled steel. As an example, a hot rolled steel product may have a yield strength of 235 MPa. In comparison, a cold rolled steel product with the same chemical composition has a yield strength of 365 MPa. The main advantages of cold working are:Accurate finished dimensions. Hot Rolled Steel vs. Cold Rolled Steel Swanton WeldingJul 21, 2016 · Examples of cold rolled steel products include; bars, strips, rods and sheets. These products are normally smaller than hot-rolled ones. Some advantages of this process include:High rate of production. Good finish and good dimensional accuracy. Suitable for among others, the production of foils, plates and sheets. Disadvantages include:

How to:A Beginner's Guide To Welding

    • MIG Welding. New welders just learning how to weld should start with metal inert gas (MIG) TIG Welding. Tungsten inert gas (TIG) welding requires more skill and takes longer than MIG Flux-Cored Welding. A third type of welding, called flux-cored arc welding (FCAW), uses a Stick Welding. Otherwise known as shielded metal arc welding (SMAW), stick welding is a two Welding Equipment. Once the method of welding has been decided, the next step is to select the Welding Materials. Materials needed for welding include consumables, such as MIG wire and flux Welding Methods. Each welder develops his or her preferred welding techniques. One of the most Material Differences.
