What are the welding requirements for steel grating? Welding technology of steel grating is also a method, then poor welding technology is also poor process, welding technology also determines the quality of steel grating, so having good welding technology can help enterprises to sell better products, then steel grating What are the welding requirements? The following editors from Biaoliang Steel Grating Factory will tell you in detail.
Manual welding: Weld the cross bar of the steel grating with the load-bearing flat steel by carbon dioxide shielded welding, and then wrap the edges. Welding machine: Weld with automatic large-scale pressure welding machine. After welding, cut into the size required by the user, and then carry out edge wrapping.
Steel grating is made of load-bearing flat steel and cross-bar cross-welded, divided into two types: manual welding and machine welding. The hand welded steel grating is to open the load-bearing flat steel, then put the load-bearing flat steel into the pre-designed mold, put the cross bar into the opening of the flat steel, and weld it with carbon dioxide shielded welding. Manual welding
Connected steel grating can produce steel grating products of any shape, regardless of machine format, ideal for orders with particularly messy dimensions. Hand welded steel grating can be used to produce twisted steel grating, plug-in steel grating and other highly adaptable steel grating types.
Machine-welded steel grating is to place the load-bearing flat steel in the pre-designed mold on the steel grating. The gratings are fused together to make the original steel grating, and then the original steel grating is cut according to the external dimensions required by the user.
Cut and edging. Only steel gratings of conventional specifications can be welded, and large flat steel thicknesses or plug-in steel gratings cannot be produced.
Conventional treatment method of steel grating
At present, the main cleaning methods of paint deposits on the grille are incineration, soaking paint remover, water jet, etc. But they all have the following disadvantages:
1. The incineration method will produce a large amount of toxic gas and seriously pollute the environment, which has been strictly prohibited by the environmental protection department.
2. The paint stripper soaking method, because it contains strong acid and organic solvent, is highly corrosive, flammable, and dangerous when used. Moreover, since the paint deposited on the steel grating is relatively thick and stubborn, the amount of paint remover will be large and the cost will be high.
3. The water jet method is currently a widely used treatment method, but it has disadvantages such as high energy consumption, high equipment maintenance costs, and large safety hazards.
