Description
| Properties |
| All-round, general purpose rutile electrode for thin and medium thick plates. Good striking and restriking properties, suitable for tack welding. Useful for bridging gaps. FAMILIARC™ LB-52U is the world's No. 1 covered electrode for uranami welding, or the root -pass melt-through welding with penetration beads. With FAMILIARC™ LB-52U your welding will be easier and faster, and you will have confidence in the quality of your welds in any kind of pipe welding of mild steel and 490MPA high tensile steel. Inception of FAMILIARC™ LB-52U FAMILIARC™ LB-52U was developed around 1954. The letter "L" stands for low hydrogen, while "B" symbolizes a slag shielding covered electrode. The digits "52" refer to the level of approximate tensile strength of the deposited metal when it was developed. The letter "U" was coined from "uranami" welding. What Makes FAMILIARC™ LB-52U the Best for "Uranami"(*) Welding? (*) Unsurpassed usability in all-position welding. FAMILIARC™ LB-52U features a very stable arc and low spatter over a wide range of welding currents. In particular, FAMILIARC™ LB-52U really shines in the "uranami" welding of horizontally fixed pipes. FAMILIARC™ LB-52U features very smooth, glossy "uranami" beads, or the penetration beads protruded on the reverse side of the groove. FAMILIARC™ LB-52U can accommodate wider tolerance of the root opening, which is an advantage in site welding . Once you have used FAMILIARC™ LB-52U, you will choose it again and again for unsurpassed performance. |
Typical Applications |
 |
| Use the keyhole technique. Right after yo get the arc by striking the groove face control the molten pool to form the keyhole crater: then manipulate the electrode along the edge of the keyhole by using the semi-weaving technique - Fig. 1 |
Typical Applications |
 |
| Control the weld penetration in the root of the groove by controlling the arc exposure spot, the electrode holding angle and the electrode oscillation width - Fig. 2 (a, b, c, d). Fig. 2a relates to the other figures of (b), (c) and (d) respectively. |
Typical Applications |
 |
| Terminate the crater on the groove face in order to prevent the crater cracking - Fig.3 |
