It is not a secret that welding machines are used in various industries. In practice, welding is used in the installation of buildings, for the installation of pipelines or for the manufacture of cars. Typically, for a truly reliable weld, you need electrodes with the right properties. Products are in demand among consumers LB 52u , which are manufactured by the Japanese company Kobelco. These products are used for welding various carbon steel structures and elements with low alloying additives. In practice, SSSI cathodes are analogous to LB 52u. Both some and other products are coated with fluorine, magnesium and calcium carbonate, these products can be used under any conditions.
Some important advantages of LB 52u products
Meanwhile, LB 52u is produced in four diameter modifications. The manufacturer produces samples with a diameter of 2.6, 3.2, 4.0, 5.0 millimeters. For example, an electrode with a diameter of 2.6 millimeters has a length of three hundred and fifty millimeters and is operated at a current strength of sixty to ninety amperes. LB 52u is used with AC or DC current, has a maximum flow of 530 MPa, a finished product weighs about five kilograms, a strength limit of 588 MPa and is classified according to E7016-1 /AWS A5.1. In such electrodes after welding there is about 0.51% silicon, 0.005% sulfur, 0.06% carbon and 1% manganese. Each welding device has such advantages as: good quality and ductility of the weld, reduced spattering of metal particles during welding, low hydrogen concentration, quick slag separation, the ability to process metal to a great depth and good impact strength of the finished joint.
Useful tips for using LB 52u electrodes
To increase the strength of the weld, it is advisable for welders to dry the electrodes for thirty to fifty minutes. It is worth starting welding at low current values, and then applying other values. Electrodes with a diameter of 2.6 millimeters are good for covering and so-called root layers. To obtain a reliable and beautiful seam, it is advisable to choose the optimal gap, as well as set the desired current level. Japanese electrodes have shown themselves remarkably in the oil and gas industry and shipbuilding, in the production of metal pipes for sewage, they work stably in different conditions.
