  • Larger and Stronger PenstocksFiller Metals For Ht490, Ht570 and HT780 SteelsStrong and Tough Fi Ller Metals For HT950 SteelHigh-Tech Welding Procedures Are Required in The Construction of PenstocksPenstock scale is generally determined by the product of the water head and the inner diameter ([H] x [D]) for which the penstock is designed. As shown in Figure 2, the scale of penstocks in Japan has continually increased since 1955 as a result of the scalingup of pumped storage hydropower stations. Accordingly, the tensile strength of steels used in penstocks has increased to reduce construction terms and costs. Whereas 780 MPa class (HT780) high tensile strength steel was used extensively in many pWELDING CONSUMABLES - Lincoln ElectricDeposit Composition %C %Mn %Si %P %S Typical Results - As Welded <0.08 1.00-1.20 0.30-0.45 <0.025 <0.020 Suitable for a wide range of mild and low allow steels Used for general construction welding applications such as bridges, buildings and pressure vessels Workhorse low hydrogen electrode for repair of mining and farming equipment Welding
