Suitable for filling welding in pipe welding work. Or in welded joints of mild steel and high tensile strength steel, 490 MPa
LB-52U welding electrode is a specially designed low-hydrogen type insulated electrode. For filling welding in pipe welding and general steel structure work, LB-52U welding wire provides very stable arc. As a result, the filling of the filling is very easy. Using a low level of welding current. In addition, LB-52U also provides a beautiful smooth surface weld. And easy to knock out
1) The electrodes should be baked before use at 300-350oC for 30-60 minutes. 2) Beautiful stuffed welds This can be achieved by selecting the welding current and preparing the appropriate groove spacing. 3) in starting arc Should start on small workpieces Outside welding groove Or may start at the edge of the weld groove To prevent the formation of bubbles at the beginning of the weld 4) In extinguishing the arc when the wire runs out The arc flame shall be extinguished at the area of the weld groove edge to prevent cracking at the wire stop. 5) Keep the arc distance as short as possible. To prevent the arc flame extinguished And prevent the formation of air bubbles
