adhesive aluminum backed strips

• Concept

1. The one-side welding backing blocks are ceramic products widely used in one-side welding technique of CO2 semi-automatic welding. They are suitable for use as welding backing material in shipbuilding ,bridges, chemical industry and other steel structure.

2. The application in a flexible way of one side welding technique with the backing material allows to save a lot of back processes. thus ,the productivity is raised ,cost lowered and working environment improved.

• Features

1. The ceramic backing block use natural inorganic materials (kaolin, talc) which are mixed the right proportion to form a ceramic powder, shaped under pressure and baked at a high temperature of 1350-1400°C.

2. Due to having been backed at high temperature, the blocks have excellent resistance to heat shocks in course of rapid heating or cooling. Under the high temperature of welding, they remain stable without producing molten metal drops and in the same time a good back bead is formed.

3. Ceramic materials have the fine property of acid and alkali resistively. Therefore, in process of steel pieces welding, no deformation and no physical or chemical reactions occur.
