摘要： Provided is a multi-electrode submerged arc welding method that enables, in multi-electrode submerged arc welding using five or six electrodes, a deep penetration and a large amount of deposit metal to be obtained by supplying a large current, and enables stable arc to be generated by respective electrodes by suppressing magnetic interference. In addition, welding defects can be prevented, and beads with a good shape or appearance can be obtained. Furthermore, the welding speed can be increased.
In the multi-electrode submerged arc welding method for butt welding of a thick steel plate with a thickness of 15 to 45 mm by using multiple electrodes, a distance between electrodes, current densities of welding currents and angles of electrodes are appropriately set.

摘要： A double tube for welded structure comprises an inside tube of a heat resistant ferritic steel and an outside tube of a heat resistant austenitic steel. The inside tube has a chemical composition which comprises specific amounts of C, Si, Mn P, S, Ni + Cu, Cr, Mo + W, V, Nb, Ti, B, Al, N and O with the balance of Fe and impurities. The outside tube has a chemical composition which comprises specific amounts of C, Si, Mn, P, S, Ni, Cr, Al, N and O with the balance of Fe and impurities. A fillet weld zone, which satisfies Formula of [wall thickness of outside tube ‰¥ fusion depth in fillet weld + 0.3 mm], is formed on the outside surface of the double tube, and the wall thicknesses (mm) of the outside tube and inside tube satisfy Formula of [wall thickness of outside tube / (wall thickness of outside tube + wall thickness of inside tube) ‰¤ 0.4]. The double tube is excellent in weld crack resistance. If this double tube is used, a welded structure forming various types of high-temperature equipment can be manufactured by fillet-welding plates, metal fittings, and the like to the outside surface of the tube by means of ordinary submerged arc welding without performing treatment such as preheating, postheating, and cleaning of steel. The inside tube may contain one or more kinds of elements selected from Ca, Mg and REM, and the outside tube may contain one or more kinds of elements selected from Mo, W, Cu, Co, Nb, Ti, V, B, Ca, Mg and REM.

摘要： Embodiments of welding systems (100) and of a welding method are disclosed. A welding system (100) includes a waveform generator (107) to generate a welding waveform with an adjustable DC offset and duty cycle. A sensor (139) of the welding system (100) senses a welding parameter at a welding electrode during a welding operation. A controller (110) of the welding system (100) is coupled to the sensor (139) and the waveform generator (107) and compares the welding parameter to a pre-defined parameter. The controller (110) adjusts at least one of the DC offset and the duty cycle of the welding waveform in response to comparing the welding parameter to the pre-defined parameter to control a stick-out distance of the electrode.

摘要： An electric melting method for forming metal components. The method provides an electric melting head (6) and a base material (2) being connected to the anode and the cathode of a power supply (12). During the forming of the component, the raw metal wire (1) is sent to the base material (2) via the feeder (5) and the electric melting head (6) to generate electric arc (9) between the raw wire (1) and the base material (2) under the protection of the deposition of granular auxiliary material (3). The electric arc melts a part of the deposited auxiliary material (3) and creates a molten slag pool (8). Electric current flows through the raw wire (1) and the molten slag pool (8), and generates the resistance heat and the electroslag heat. The raw wire (1) is molten under the high-energy heat resource composed of the electric arc heat, the resistance heat and the electroslag heat, and thereby creating a molten pool (11) on partial surface of the base material (2). The raw wire (1) and the auxiliary material (3) are fed continuously and a computer is employed to control the relative movement of the electric melting head (6) and the base material (2) based on laminated slicing data, such that the molten pool (11) is rapidly cooled, solidified and deposited on the base material (2), and thus the metal component with desired shape and size are formed after the layer-to-layer deposition.
