To solve the problem of welding of fi llet welds with leg in one pass of more than 6...8 mm due to the draining of metal from vertical wall it is proposed to use two-electrode welding. The computer analysis of this process showed that acceptable formation of the fi llet weld can be achieved by optimizing of the welding process parameters, including the positioning of electrodes relative to the weld. Due to this, it is possible to provide leg of welds upon welding up to 12 mm. However, large legs of fi llet welds in twin-arc submerged arc welding can be obtained only if the distance between the arcs is suffi cient in order to form separate weld pools, and one of the arcs will be shifted by leg half on the vertical wall.

The pressure vessel steel is used in boilers and pressure vessel structure applications. This research studied the effects of submerged arc welding (SAW) process parameters on the mechanical properties of this steel. The weld sample originated from ASTM A283 grade A sheet of 6.00-millimeter thickness. The welding sample was treated using SAW with the variation of three process factors. For the first factor, welding currents of 260, 270, and 280 amperes were investigated. The second factor assessed the travel speed, which was tested at both 10 and 11 millimeters/second. The third factor examined the voltage parameter, which was varied between 28 and 33 volts. Each welding condition was conducted randomly, and each condition was tested a total of three times, using full factorial design. The resulting materials were examined using tensile strength and hardness tests and were observed with optical microscopy (OM) and scanning electron microscopy (SEM). The results showed that the welding current, voltage, and travel speed significantly affected the tensile strength and hardness (P value < 0.05). The optimum SAW parameters were 270 amperes, 33 volts, and 10 millimeters/second travel speed. High density and fine pearlite were discovered and resulted in increased material tensile strength and hardness.
