## 1 Introduction  
With the developments in marine engineering, aeronautics and aerospace, transportation and other industries, welding technology has undergone continuous development. Improving the efficiency of welding production, achieving welding automation, and improving welding quality have become key issues in the development of welding technology [1]. Twin wire Double Pulsed Metal Inert Gas (GMAW) welding technology can perform high-speed welding and achieve a high deposition rate and is therefore considered a promising topic for research internationally [2; 3; 4] with many researchers being actively involved in related studies. [PERSON] et al. studied the effects of the inclination angle between the leading and trailing wire, the twin wire spacing and the welding current ratio on the formation of weld bead in the high-speed welding process. With the basic requirements of avoiding undercut and hump bead, the best set of parameters for high-speed welding was obtained with a welding speed up to 4.5 m/min [5]; [PERSON] et al. investigated the effects of the distance between the leading and trailing wire and the mixing ratio of gas on the abnormal arc voltage and arc interruption in twin-wire GMAW welding. Additionally, the reasonable ranges for welding wire distance and gas mixing ratio were given [6]. Through pulse timing control and arc length control of the twin wire GMAW welding, [PERSON] and other researchers succeeded in minimizing the arc intervention, avoiding arc interruption, establishing stable control using arc length control and confirming that the stable control is not affected by the fluctuation in the feeding speed and length extension of the wire [7]. Considering the steel plate welding process applied in the shipbuilding industry, [PERSON] and other researchers investigated the formation mechanism of solidified cracks in twin wire GMAW welding and proposed a solution to diminish the crack generation [8]. [PERSON] et al. studied the stability of three phase arcs: independent, alternating, and independent of twin wire DP-GMAW welding and its effects on weld quality and microstructure [9]. [PERSON] et al. predicted the transient temperature distributions and temperature variations of the welded plates during welding [10]. [PERSON] et al. analyzed temperature distribution in butt weld joints, and successive thermo-mechanical analyses were performed to evaluate resulting residual stresses [11]. [PERSON] et al. analyzed the effects of various FCAW welding parameters on weld width and tensile properties of weld metal extracted of butt joint [12]. [PERSON] et al. used a parametric model and the elements birth and death in single-pass butt welded joint to simulate the weld filler variation with time [13]. [PERSON] et al. studied the effect of area-filling paths on the residual stresses developed during twin-wire arc weld-deposition [14]. [PERSON] et al. studied the bypass coupling technique which was employed in twin-wire indirect arc welding (TWIAW) to improve its penetration [15]. [PERSON] et al. investigated microstructural evolution and mechanical properties of an ultra-high strength structural steel welded joint at different heat inputs in the metal active gas arc (MAG) welding technique [16]. [PERSON] et al. studied the microstructures, penetration and mechanism of the welding joint by twin wire Metal Inert Gas (MIG) welding with Cr\({}_{2}\)O\({}_{3}\) activating flux [17]. [PERSON] et al. investigated a three-component shielding gas mixture used in tandem with narrow gap pulsed GMAW, and the effect of its composition on arc behaviors and weld formation [18]. [PERSON] et al. investigated the effects of arc length, torch angle, and high-frequency current pulsing on the arc resistance to extinction in tandem GMAW [19]. The researchers showed results that an increase in the welding speed brings to the fore some issues that are different from those in conventional welding.
