Kobe LB-52U Root Pass Welding Electrodes
Steel type: Mild steel/High tensile steel
One-side shielded metal arc welding of pipes and general butt joints of mild steel and 490N/mm2 high tensile steel.
LB-52U is a low hydrogen type covered electrode for exclusive use for one-side welding of pipes and general structures.
Its arc stability is extremely good to perform one-side welding with relatively low currents.
LB-52U provides good slag removability and smooth weld beads.
(1) Dry the electrodes at 300-350ºC for 30-60 minutes before use.
(2) Reverse side bead with good appearance is obtained with proper current and optimum root gap.
(3) Cut off the arc after setting the crater to the side wall of the groove to avoid crater cracks.
(4) Strike the arc on a small steel plate prepared for this purpose or on the side wall of the groove to prevent blowholes at the arc starting.
(5) Keep the arc as short as possible.
