These types of materials are painted and covered flux around core steel rod.
[ Characteristics ]
Shielding gas is unnecessary because of intercepting the atmosphere and the arc by resolute gas from coating flux. SMAW(Shield Metal Arc Welding) is simple and easy welding method , and possible to weld under strong wind.
Shape of many type of these materials is steel rod, and including some elements. In addition, some materials are coated copper and the others have flux cored structure.
[ Characteristics ]
GTAW(Gas Tungsten Arc Welding) is clean process because of generating non-spatter and non-fume, has good bead appearance and mechanical properties of weld metal, is able to apply to all kind of metals. Shield of the arc from atmosphere perform to blow inert gas i.e. Argon. GTAW is many used to pipe welding or repair welding.
Shape of these materials is small diameter steel wire including some elements. In addition, there is copper coated type and non-coated type. These wires are packed in spool(bobbin) or large drum-pack container.
[ Characteristics ]
These materials are most popular in Japan, and used to semi-automatic welding by human welder or automatic welding by robot. Shield of the arc from atmosphere perform to blow CO2 gas or mixture gas of CO2 and Argon.
These wires have dual structure that inner is flux and outer sheath is cylindrical thin steel plate. In addition, there is copper coated type and non-coated type. These wires are packed in spool(bobbin) or large drum-pack container.
[ Characteristics ]
These wires generate fewer spatter and better bead appearance than the solid wires at fillet or vertical form welding. These are many used to ship-building or bridge construction. In addition, there are unnecessary types of shielding gas, too.
Shape of these materials is large diameter steel wire including some elements. But there are flux cored types in a part. These wires are mainly packed in non-spool (bobbin) coil type. These are used in combination with the following flux.
[ Characteristics ]
SAW(Submerged Arc Welding) can used in ultra high current range and become very high efficiency by more than two electrodes system. In addition, generates no arc rays, has good bead appearance and is not affected by the strong wind.
The fluxes are mixed powdery materials contained some elements. And, soled in the steel drum or bag made by paper or cloth..
[ Characteristics ]
The fluxes are filled in welded groove of base metal, and then covered the arc on welding. Kind of these have the melting type and the bonding type by the difference in manufacturing method.
These are welding materials of ribbon shape with suitable width.
[ Characteristics ]
Strip electrodes are used in the overlay welding on another base metal surface. High efficiency work is possible because of very wide bead. Kind of welding method has the submerged arc welding (SAW) or the electro-slag welding (ESW).
