How grating is made?
(2021-01-22)
How we’re different?

In 1997,we began to manufacture and produce welding machines.In 2006, we began to export welding machines.In recent years, owing to the advantage of technology, our output has been doubled.

We have customers from both domestic market and oversea market (Middle east, Europe, Asia, Australia, Africa, America,South America,etc). We strictly follow the standard for different markets. The standards of the steel grating products are as below:



Our machines are capable of producing steel grating in different standards for various markets.

How grating is made?

Electric welding, also known as electro-forged, is a thermoelectric process in which heat is generated by the passage of electric current. For a controlled period of time and under controlled pressure, the current passes through the junction area of the parts that wish to be welded.

This process is frequently used to manufacture steel bar grating and other types of grid.



In this manufacturing process, metals are welded without additional materials. This is achieved through the pressure and the electric current applied to the wished welded area.

During the process, metal parts (commonly steel) are pressed together by the welding machine”™s electrodes to assure a firm and constant electrical contact.

Subsequently, the electric current passes through the electrodes and heats them until their junction spot melts. The two pieces”™ of molten metal are combined and they join together. When current stops both pieces solidify, forming a solid metallic connection between both pieces.



The difficulty with this job is not only that it requires a lot of current, but also the balance between current and pressure.In addition, the welding aesthetic is also a factor to be considered.

Different sizes and shapes of steel gratings need to match different currents and pressures.Therefore, a good grating welding machine manufacturer should not only have rich experience in equipment manufacturing, but also be familiar with the knowledge of steel grating welding.

Xinzhou Welding Equipment Co., Ltd. not only has more than 20 years of experience in welding machine production, but also deep cultivation of steel grid welding machine, so that the production machine can perfectly meet the requirements of steel grating production.
