Features
of one-side welding backing material: The
ceramic backing blocks use natural inorganic material
(kaolin, talc) which are mixed in a precise formula
to form a ceramic powder shaped under pressure
and baked at high temperatures (1350-1400C).
Due
to having undergone baking in high temperatures,
the blocks have excellent resistance to heat shocks
int he course of rapid heating or cooling. Under
the high temperature of welding, they remain stable
without producing molten metal drops. At the same
time, a good back bead is formed.
Ceramic
materials have the fine property of acid and alkali
resistivity. In the process of welding steel pieces,
no deformation, physical or chemical reactions
occur.
The
adhesive aluminum tape contains no halogen and
no chemical reactions occur during the
process. |
