Description

Technical Field

[0002] Gantry welding equipment is a type of welding equipment commonly used in industrial production. It uses a gantry operating frame as the main frame of the equipment, providing support and a moving track for the welding head and related components. It is usually welded from structural steel or steel plates. The working principle of gantry welding equipment is to accurately position the welding head to the weld position of the workpiece to be welded through the coordinated action of the traveling mechanism, lifting mechanism and lateral moving mechanism. Then the welding head performs the welding operation according to the preset welding parameters and welding process.
