Waterproof One Side Welding Ceramic Backing Strips And Tapes GMAW Ceramic Weld
Waterproof One Side Welding Ceramic Backing Strips And Tapes
Product Description
Waterproof Ceramic Backing Strips For One Side Welding have a very smooth finish, good water-proof property,
and makes one side welding both sides beads shaped in fine quality. The improvement of working efficiency and
cost-saving are gotten by omitting the backside gouging and root passes.
Suitable for Gas Metal Arc Welding (GMAW) and Submerged Arc Welding (SAW) of V-shape, X-shape, T-shape
joints of metal structures in shipyards, off-shore buildings, heavy industries etc.
