In order to ensure that ultra-thin materials do not burn through during welding with the Plasma Tunnel Welding Machine, it is necessary to start from three aspects: process parameter control, equipment technology optimization, and auxiliary measures. In terms of technology, the micro-beam plasma welding mode is adopted to accurately control the welding current at 5-30A, and the pulse current output (frequency 10-50Hz, duty cycle 30%-70%) is combined to disperse the arc heat input and reduce the risk of burn-through caused by continuous heating. The arc stiffness is controlled by adjusting the ion gas flow rate (0.5-1.5L/min) to avoid excessive arc divergence.
In terms of equipment technology, it is equipped with a high-precision arc voltage tracking system to monitor the arc length in real time (accuracy ±0.05mm). When the workpiece changes height due to thermal deformation, the welding gun position is automatically adjusted. A small-aperture compression nozzle (diameter 0.8-1.2mm) is used to enhance the arc compressibility, make the energy more concentrated, and reduce the heat-affected zone.
In addition, the ultra-thin material is pre-fixed before welding, and a vacuum adsorption tool (adsorption force ≥ 0.08MPa) is used to ensure the flatness of the workpiece; during welding, protective gas (argon gas purity 99.99%) is introduced to cool both sides of the weld to reduce heat accumulation. These measures can effectively prevent ultra-thin materials from burning through during welding and ensure welding quality.
