AWS A5.17 / ASME SFA5.17 F7A4-EL8 JIS Z3183 S502-H

Single-layer welding of ship buildings, structural steels, bridges and heavy duty structures.

As the penetration is deep, it is suitable for welding of thick plate in both side single-layer welding. Impact properties of weld metal and crack resistibility are excellent. Also applicable to one-side welding. As the consumption of flux is small, it is economical. Notes on Usage Dry the flux at 300~350 (572~662 ) for 60 minutes before use. Pay attention to welding voltage. Excessive welding voltage causes deterioration of joint properties. Add new flux periodically to prevent the weld defects and bad bead appearance which occurs when continuously reusing the flux. Not applicable to multi-layer welding with more than 3 passes.

Multi-layer welding of various kinds structure such as ship buildings, offshore structures, pressure vessels. It produces the weld metal which has excellent impact value at low temperature down to -60 and CTOD at temperature down to -10 . As the hydrogen content of weld metal is extremely low, it shows excellent resistance to crack. Tandem, multi-electrode can be performed. AC power source is recommendable because DC makes inferior quality. Notes on Usage

Excellent notch toughness at low temperature down to -60 (-76 ). Suitable for single and multi-layer welding of TMCP steel. Resistance to pockmark and porosity are excellent. Slag detachability in the groove is good. Notes on Usage Dry the flux at 300~350 (572~662 ) for 60 minutes before use. In case of multi-layer welding, use welding current and speed as low as possible at the first layer of groove to avoid cracking.

Butt and flat fillet welding of miniature LPG tanks, spiral pipes, ships, vehicles, agricultural implements, machincery, cars, boilers, bridges and structural steels.

Butt and flat fillet welding of thin and medium thickness plates. High travel speed welding for miniature LPG tanks. Longitudinal pipes welding or spiral pipes welding of thin and medium walled pipes. Especially insensitive to oil, rust, scale, and dirt on the surface to be welded. Slag detachability in narrow groove and resistance to porosity are excellent. Suitable for welding of thin and medium plate in high speed welding. As the consumption of flux is very small, it is very economical. Applicable to horizontal and flat fillet welding. Notes on Usage Dry the flux at 300~350 (572~662 ) for 60 minutes before use. When the flux height is excessive, poor bead appearance may occur. Remove rust, scales, oil, paint, water, dirt and slag of tack welds from the groove to obtain sound weld metal Use welding current and speed as low as possible at the first layer of groove to avoid cracking. Approval Current AC, DC+

Applications Welding of 18%Cr-8%Ni stainless steel. Characteristics on Usage

JIS Z3324 FSS-B1/YS308(L)

Applications Butt and flat fillet welding of buildings, bridges and API Linepipe. Characteristics on Usage S-800P is a basic agglomerated, slightly Si-alloying flux for submerged arc welding, specially for single and multipass butt welding of mild, medium and high tensile steels. It provides good bead appearance and better slag removal together good impact value of the weld metal. It is relatively insenitive to rust and dirt on a base metal, and makes better resistance to porkmaks and pits. As the consumption of flux is very small, it is very economical. Notes on Usage Dry the flux at 300~350 (572~662 ) for 60 minutes before use. When the flux height is excessive, poor bead appearance may occur. Use welding current and speed as low as possible at the first layer of groove to avoid cracking.

Bonded type-flux containing proper contents of alloying element and weld metal contains proper contents of ferrite. Excellent resistance to crack, mechanical property and corrosion. Excellent weldability such as stable arc and easy slag removal. Beautiful bead appearance, high welding efficiency in welding thin plate up to ultra-thick plate. Notes on Usage Dry the flux at 300~350 (572~662 ) for 1 hour before use. Avoid using high current to prevent harming of corrosion-resistibility in heat-affected zone. Heat-input in welding should be kept as low as possible. Welding in groove should be done in 2 passes to ease slag removal.
