Yawata is a manufacturer for premium welding filler metal situated in Thailand. It partners with Nippon Steel Welding and Engineering (Japan) in the development and manufacturing of its filler metal. With the renowned Japanese technology and Thai craftsmanship, Yawata sets out to produce only the highest quality products for its customers.
In this article, we will explore on some of the Yawata electrodes that are used commonly in the metal fabrication industry.
Yawata S-13 (E6013)
Yawata S-13 is a high rutile type electrode for all positions welding except vertical downward. Special characteristics are soft arc, less spatter, good for tack welding, self-lifting slag, giving shiny and beautiful beads. There is no fear of burning through. It is commonly used for welding of mild steel sheet, pipes and light gauges for drums and structure. Can be used on galvanized steel too.
Yawata FT-51 (E6013)
Yawata FT-51 is a high rutile type electrode for all positions welding and assures easy operation even in vertical downward position. Spatters are less and bead appearance is beautiful. FT-51 gives a stronger arc as compared to S-13 and has higher deposition rate. It is used in welding of mild steel sheet for ships, rolling-stocks, structures, and finished welding of heavy structural works.
Yawata L-55 (E7016)
Yawata L-55 is a low hydrogen type electrode for all positions welding. Deposited metal shows excellent crack resistance, mechanical properties and X-ray quality. Vertical and overhead welding are very easy. Easy to start arc and welding gives no porosity. It is used for welding of 490 N/mm2 high tensile strength steels for ships, structures, large diameter pipes and bridges.
Yawata 7018 (E7018)
Yawata 7018 is an iron powder low hydrogen type electrode containing a large amount of iron powder in coating flux. Deposited metal gives excellent mechanical properties, crack resistance and X-ray quality. Weldability is good and high welding efficiency is obtained. 7018 has a higher welding deposition rate compared to L-55. It is used for welding of 490 N/mm2 high tensile strength steels for ships, steel frames, bridges and pressure vessels.
