AWS E7018 Mild Steel Electrodes Welding Rod

7018 mild steel electrodes description: mild steel electrodes a high deposition electrode for low and medium carbon steels. It is an efficient, iron powder, low hydrogen electrode with excellent mechanical properties; crack resistance; and x-ray quality welds. This electrode offers a quiet, stable, low penetration, spatter-free arc. The moderately heavy slag is easy to remove, revealing a bead with distinct ripples. Operator appeal is a plus factor. Typical application:  ship hull construction, pressure vessels, boilers, piping, heavy duty equipment, general maintenance or production fabrication. .application: the welding electrode e6013 is widely used on both ac and dc in all positions and suitably for welding sheet metal structure made of low-carbon steel,such as ships,vehicles,building,and general machinery.  packaging: size: 2.5mm x 300mm (packing: 2.5kg/inner boxes 8boxes/cartons=20kg) size: 3.2mm x 350mm (packing: 5.0kg/inner boxes 4boxes/cartons=20kg) size: 4.0mm x 400mm (packing: 5.0kg/inner boxes 4boxes/cartons=20kg)  chemical composition of deposited metal(%) chemical composition c mn si s p guarantee value ≤0.12 0.3~0.6 ≤0.35 ≤0.035 ≤0.040  mechanical properties of deposited metal test item  rm(mpa) rel(mpa) a(%) kv2(j) kv2(j) guarantee value ≥420 ≥330 ≥17 -(normal temperature) -(0°c) general result 460~540 ≥340 18~26 50~80 ≥47  reference current (ac/dc) model rod
