TOKO Brand E7018 Carbon Steel Welding Electrodes Perfomed in Vertical Down Welding
Comapny Introduction
TOKO, We aim to be the leaders in the welding industry, with our innovative products & remarkable portfolio. Our positive attitude, determined approach and innovative solutions will help us bring world-class welding solutions accessible to one and all.
Product Description
AWS A5.1 E7018 is an outstanding quality all position welding electrode covered with extra low hydrogen potassium type coating for high tensile strength mild steels and low alloy steels. Its nominal welding efficiency is about 110% due to iron powder is contained. The weld metal shows an excellent low temperature toughness and high crack-resistance.
It is widely used in important projects of ship, boilers, high pressure vessels, bridges, skyscrapers, offshore drilling platforms, nuclear power plants and so on. The groove of base metal should be cleared impurities away and the electrode must be baked at 400ºC then be held 1-2 hours before welding, 2.5mm or less one should be done by 350ºC then be held 1 hour.
