What is submerged arc welding?

welding a submerged arc, often the abbreviation saw, is a specific and popular type of arc welding, where the molten and welded area is covered with a blanket of flow. This provides several benefits to welders, ranging from UV radiation to higher quality. Traditional arc welding uses electricity to create an arch of electricity between the electrode and the processing of metal. This electric arc melts and connects the materials together and can be ensured either by direct current (DC) or alternating current (AC). Flux is a material that, after melting, creates a way for the electric arch that passes. The arch travels from the electrode, through the flow and to the material that needs to be welded. This method can also use direct or alternating current.

For this t has many advantages of type welding. Since the weld is immersed, it prevents hot material to spray and spray back. The flow also helps to prevent emitting high levels of UV radiation. There is no need for pressure to create a weld because the electronican current performs work. It not only provides these advantages over other forms, but this type of welding is excellent for the rapid connection of thin metal leaves and creates a good fusion between materials.

This process can be performed both in the interior and outdoors, wherever it is best to place the device. To ensure that the flow remains in the correct position, welding must be made on a flat and horizontal surface; Otherwise, the flow could move and cause incorrect weld. After the correct design, the submerged arc welding will bring results that are of high quality and look good.

However, there are disadvantages to this method. Although this helps prelodvyzing and radiation, the materials on which can be used are limited. Steel and stainless steel are the most common types that work with this type of welding, along with certain nickel -based alloys. There are also concerns about the safety of the flow because they needNCI Dangerous residues can be left behind.
