The EGW welding used by the tank welding machine is gas-electric vertical welding, which is a gas-shielded arc welding method developed from ordinary gas-shielded gas welding and electroslag welding. The advantages are high productivity and low cost. The main difference with narrow gap welding is that the weld is formed in one pass, rather than multi-pass multi-layer welding.

What is the operation method of tank welding machine?
(1) Left welding method (right→left): small residual height, large width and small splash, which is easy to observe the welding seam, the welding process is stable, the gas shielding effect is good, but the depth of dissolution is shallow.
(2) Right welding method (left→right): The remaining height is large, the width is small, and the splash is large, which is convenient for observing the molten pool and the depth of the molten metal.
(3) Gun delivery method: zigzag swing.
(4) Flat fillet welding does not swing or swing slightly.
(5) The vertical angle is welded upward, and the triangular gun is used.
(6) Welding torch transition: stay on both sides of the molten pool and transition at the front 1/3 of the molten pool.
(7) Gun angle: perpendicular to the weld bead, at an angle of 80-90° along the direction of the gun.
(8) Test plate: the gap is 2.0-2.5mm, and the arc starting point is slightly smaller than the arc ending point. No blunt edge, anti-deformation 1°.
(9) To prevent defects: prevent the angle from melting - burn through the angle. No fusion between layers - pay attention to the gun angle.
The direction of the arc axis of the tank welding machine is perpendicular to the direction of the penetration depth of the weld. During welding, a water-cooled copper slider is used on the front of the weld, and a water-cooled gear row (or pad) is used on the back of the weld. The flux-cored wire is fed into the weldment and in the groove formed by the stopper, the four sides of the molten pool are constrained to realize single-sided welding and double-sided forming at one time. Tank welding machine is a high-efficiency welding technology and equipment.
In recent years, the promotion and application of tank welding machine in engineering has achieved good results, and in-depth research on the fusion welding mechanism of gas-electric vertical welding technology. Tank welding machine has good welding quality, high deposition speed and low comprehensive cost, which provides a broad prospect for the popularization and application of this efficient automatic welding technology and equipment.
