The Given

The given work considers the influence of the power supply type (diode rectifier DR-306 and inverter Nebula-315) upon the chemical composition, microstructure, mechanical properties of weld joints and upon health characteristics of the manual arc welding process.It has been ascertained that the power supply type has a significant influence upon the weld joints properties and health characteristics of the manual arc welding process. Using a new generation inverter power supply allows less heat input into the weld bead, thus, decreasing silicium and manganese burning, improving impact resistance of weld joints under low (negative) temperature and reduces the risk of respiratory diseases for the workers.

Arc Welding Process

The occupational risk assessment of a machine building company must cover each activity and workstation, taking into account each component of the production system (work system), each workload, work equipment and the work environment. This assessment is an extremely complicated and complex issue since the production system of such an enterprise is particularly complex and complicated. Welding assembly is a highly polluting technology process, especially of the atmosphere and soil. The formation of gases in the welding process is the result of burning of the electrodes, powders, forming the molten metal bath and making the weld seam. Welding operators are exposed to smoke and toxic gases resulting from the welding process, which can in many cases be hazardous to health. Many acute intoxications that may be caused by excessive exposure to or short exposure to smoke and gas resulting from the welding process have been studied over time. In the paper are presented the elements of risk related to the welding process and the most widespread occupational diseases that can occur in the ranges of the welding operators. The following are presented the noxious emissions from welding and are determined by a practical method the emission of noxious at welding deposition of a welding sample, using the manual arc welding process with coated electrode.

Metal inert gas arc welding process was implemented to join 6063T6 wrought alloy and ADC12 die-casting alloy using ER4047 filler metal. The microstructure of the weld seam and weld interface was investigated. The bonding strength of the butt joints was tested by Charpy U-notch impact test and tensile test. The results showed that a sound welding butt joint with finely silicon particles and excellent mechanical properties was formed, and the size of the silicon particles was nearly 2 μm. Compared with 6063T6 wrought alloy, the impact absorbing energies and the tensile strengths of the butt joint were higher and reached 1.173 kJ/cm2 and 205 MPa, respectively, and the fractures of all tensile specimens occur at the 6063T6 aluminum.

Welding Processes

During the past 30 years, many new welding processes have been applied to the fabrication of various metal structures. However, these processes have largely been ignored by the shipbuilding industry, and modern ships continue to be fabricated primarily by a manual arc-welding process that is more than fifty years old. This paper discusses some of the problems related to welding ship structures, focusing mainly upon two important subject areas:new welding processes, andnotch toughness of weld metal. The author reviews briefly developments in the technology and, emphasizing the technical problems, indicates how research can improve the state of the art.

This paper reports on an investigation into the benefits of using new-generation flux-cored electrodes in the submerged arc welding process. The validity of manufacturers' claims of improved physical properties and economies of welds produced with the new electrode is examined by comparison with standard solid electrode performance. The tests are based on application of weld metal to four different grades of steel common to both commercial and naval ship construction. The authors conclude that for some, but not all, applications, the flux-cored—or tubular—electrode is a marked improvement.
