How about the welding performance of a573 grade 58 structural steel carbon plate

For the team, cooperation is the core idea of daily work, and the core of common cooperation is resource sharing. With a perfect resource sharing mechanism, the whole team can be called a unity spirit.A good team lies in the ability to transfer resources, knowledge and information in time among team members in order to achieve the common goals of the team. So that we can share experiences and lessons."

Composite steel plate is a composite steel plate which is made of carbon steel or low alloy steel as the base material and coated with stainless steel, titanium alloy, a573 grade 58 structural steel carbon plate and other composite materials, or sandwiched with other metal or non-metal materials between two layers of steel and processed by pressure or blasting. It is mainly used to make chemical equipment and chemical storage tank, or obtain special functions such as shock absorption. The manufacturing methods of composite steel plate include rolling method and explosion method, but most of them are rolling method.

a573 grade 58 structural steel carbon plate, The wear-resistant steel plate adopts the open arc self-protection automatic surfacing process, and the composite-layer is a high-alloy wear-resistant layer with high hardness and high wear resistance on the surface of the ordinary steel plate or stainless steel plate. The wear-resistant steel plate has bimetal performance. That is, the high wear resistance of the working layer and the high plastic toughness of the base layer provide convenient mechanical connection and welding rod connection conditions for industrial applications, and can realize processing such as reeling, welding, plasma cutting, and mechanical connection.
