Welded H-shaped steel is steel shape similar to the English letter H, the production steps are simple, the price is relatively low, has been widely used in life, used in the bridge, house structure, it can also be major other buildings. Because H-beam steel is a green material and can be recycled, welding speed is fast and strength is relatively high, welding is easy to weld H-beam steel can reduce the amount of material used, there is a good deformation capacity of the same area of buildings, it is smaller than the traditional I-beam steel, but also can save the cost of transportation and lifting.

Method of welding H-shaped steel

 Molten argon arc welding (GMAW) : Also known as MIG welding, is a welding method that protects the weld and electrode by adding a protective gas during the welding process. This welding method can weld H-shaped steel quickly, and the weld quality is stable, suitable for large-scale production.

 Arc welding (SMAW) : Also known as manual arc welding, is a method of welding by using electrodes to heat and melt the surface of the workpiece during the welding process. Although this welding method is time-consuming, it is suitable for small batch production and limited space.

 Gas shielded arc welding (GTAW) : Also known as TIG welding, is a welding method that uses an inert gas shielded weld. This welding method can control the heat of the welding process, so as to obtain a high-quality weld, but the speed is slow, suitable for small-scale production and high quality requirements of the weld.

 Electroslag welding (SAW) : is a method of using an arc to heat the surface of the workpiece during the welding process and add a welding rod to the weld. This welding method can quickly weld large structures, but requires the corresponding equipment and operating skills.

 It is necessary to choose the appropriate welding method according to the specific welding requirements and working environment.
