The development of modern current waveform control technology and power electronics technology has provided new methods of arc control. The GLC353 Quinto CP process (cold welding process) developed by CLOOS in Germany has more significant advantages than traditional welding processes in thin plate welding.
The heat input is controlled using a negative base current time. Practice shows that this kind of process greatly reduces the thermal influence on the base metal, and improves the welding efficiency and welding speed of the welding wire in the same time.
The special current waveform guarantees good gap filling coverage and excellent welding effect. In the normal phase, the base metal is in the cleaning stage, the heat input to the base metal is controlled, and the droplets are transferred to the base metal without splashing during the pulse phase. In the negative phase, the arc surrounds the end of the wire, heat is input to the wire, and the weld pool is cooled.
Reduce heat input and minimal weld distortion, making the CP process especially suitable for welding high tensile sheets, stainless steel, coated sheets, aluminum alloys and MIG brazing.
Advantages of the cold welding process: 1. High welding speed - increase production efficiency. 2, strong gap coverage filling ability - can guarantee high weld quality when welding workpieces with large tolerances, and does not require high cost machining. 3. The heat input to the base metal is very low - it has better effect when welding and brazing high heat sensitive materials; the deformation of the extremely small workpiece reduces the tendency of cracks in the weld zone due to the higher temperature difference. 4. Smaller splashes - no need to clean up again. 5, can use a larger diameter of the wire - the wire cost is reduced, more stable wire feeding, improve production efficiency. 6. QUINTO CP's friendly human-machine control interface truly realizes the unified mode. The operator can set "hot welding" and "cold welding" to obtain high-quality welds in real time through a single button.
