“…Hence, the study investigated the process parameter optimization of the inner tank using numerical and experimental approach. The result indicates that sequential welding has minor impact on the reduction of the welding residual stress and deformation [7]. The study confirmed that the welding stress and deformation gave a minimum value of 170 Mpa and 0.897 mm respectively.…”

The study focused on the importance of the different welding parameters on the mechanical behavior of High Strength Steel (HSS) X65 steel pipes by reviewing the advantages of parameter optimization for the Tungsten Inert Gas (TIG) - Metal Inert Gas (MIG) welding processes. The parameters considered in the study include welding speed, welding current, welding voltage and gas flowrate of the welding. The effects of improper selection and parameter optimizations were highlighted and illustrated using different metallurgical and mechanical instances. The outcome of the study indicates that adequate parameter optimization aids in obtaining good weld quality with adequate mechanical and microstructural properties. Furthermore, it helps in the determination of variation in hardness in the heat affected zone as well as the base metal. Thus, this study provides insight to welding engineers on the importance of parameter optimization in the welding of steel pipe.

Welding processes are present in all sectors of the industry, highlighting the manufacturing industry of thick plates and pipelines. In these applications, welding processes have a major influence on costs, schedules, risk analysis and project feasibility. Conventional arc welding processes, such as the gas metal arc welding (GMAW) process, have limitations when applied to high thickness joints due to their maximum achievable penetration depth. On the other hand, the laser beam welding (LBW) welding process, despite reaching high penetration depths, has several limitations mainly regarding the geometric tolerance of the joint. In this regard, the hybrid laser-arc welding (HLAW) process emerges as a promising bonding process, combining the advantages of the GMAW and LBW processes into a single melting pool. Despite the many operational and metallurgical advantages, the HLAW process presents a high complexity due to the high number of parameters involved and the interaction between the laser beam and the electric arc. The present work discusses the challenges involved in the parametrization of the HLAW process applied to the joining of thick plates and pipes, and empirically evaluated a comparison between the HLAW and GMAW processes, showing a reduction of operating time of approximately 40 times, and a reduction of consumption of shielding gas and filler material of approximately 20 times, evidencing the technical and financial contribution of the hybrid process.

“…Also, the constructive steel plates with thickness of 30mm can be welded, in dual passes using Hybrid welding with Double Rapid Arc -HyDRA, where two torches are placed in two different sides of the plates [26]. In addition, steel plates with higher thickness can be welded by hybrid laser arc welding with multiple weld passes and optimum joint gap between the welding elements [72,73]. The HLAW is capable to bridge a joint gap up to few millimeters depending on the laser power, welding speed, filler wire feed rate as well as the material thickness [74,76].…”

“…With HLAW a wide range of materials, from ferrous metals like structural steels, stainless steels to non-ferrous metals like aluminum (Al), magnesium (Mg), Nickel (Ni) and their alloys can be welded [7,16,22,31,33,83]. Moreover, HLAW allows the welding of thin sheet metals as well as thick metal plates in one or more weld passes, however compared to conventional welding processes the number of passes are less which results in reduction of weld distortion [30,73,79,94].…”

Hybrid laser arc welding is complex process where two heat sources act simultaneously in a common weld pool. The synergy effect of laser beam and electric arc offers several advantages over other individual technological processes, such as: higher welding speed, increased productivity, deeper penetration, better gap bridging ability, stable process, less heat input to the welding material, etc. However, the combination of two heat sources in a single welding process leads to large number of parameters that need to be synchronized and optimized in order to obtain a perfect weld. This paper presents the current state of hybrid laser arc welding in terms of its development, industrial application and scientific research. The introduction part contains a general overview of the hybrid laser arc welding process, its advantages and operating principles, and chronological development. In the second part, welding parameters that directly influence on the hybrid process have been discussed. The third part presents the performance and weld qualities achieved by hybrid welding process in accordance with previous research. In the final part, examples of industrial application and conclusions for further research and development related to hybrid laser arc welding are given.
