Description

Technical Field

[0001] The utility model relates to the technical field of spot welding, in particular to a device for processing spot welding gas. Background Art

[0002] A spot welder is a mechanical device that utilizes the principle of double-sided, double-point overcurrent welding. During operation, two electrodes pressurize the workpiece, creating a certain contact resistance between the two metal layers under the pressure of the two electrodes. When the welding current flows from one electrode to the other, a thermal bond is formed at the two contact resistance points. The welding current also flows instantaneously from the other electrode along the two workpieces to this electrode, forming a loop without damaging the internal structure of the welded workpieces. Spot welders are categorized by application into universal (general-purpose) and specialized types; by the number of welds simultaneously, into single-point, dual-point, and multi-point types; and by the conduction method, into single-sided and double-sided types. The direction of movement of the active electrode (usually the upper electrode) can be vertical (linear) or circular. The power supply method includes industrial frequency welders (using a 50 Hz AC power source), pulse welders (such as DC pulse welders and energy storage welders), and variable frequency welders (such as low-frequency welders). Spot welders are often used in workpiece processing. During the use of spot welding machines, a large amount of harmful gases will be generated. When directly discharged, it will affect the working environment of personnel and have an impact on their physical health.
