La situación de partida:
In the past, alwitra used a standard pulse MIG process to manufacture components. The level of automation in the company was rather low at around 30%, as special products made up the majority of production. However, there is great potential for optimisation, particularly in the production of standard components, as increasing automation can further improve quality and reduce costs. alwitra is constantly adapting its product range to current market requirements and is therefore all the more dependent on the use of innovative welding technology.
La solución:
Process stability plays an important role for alwitra when using welding robots. This is where EWM React comes into play as an automation solution, as the welding process is the ideal combination of short arc and digital welding process control. Combined with a highly dynamic torch drive, the result is a precise and reliable automation process that delivers perfect welds. EWM React gives the user full control over the droplet transfer and, with the process variants Speed, Positionweld and superPulse, offers tailor-made solutions for even the most demanding welding tasks.
El éxito:
The objective of the cooperation between alwitra and EWM was clearly defined: Automated welding was to take productivity to a new level. This is exactly what has been achieved with EWM React, as the high deposition rates of the spray arc range have been combined with all the advantages of the short arc. Hardly any spatter, minimal distortion, enormous process stability and a reduction in heat input of up to 35% - these advantages speak for themselves. With alwitra, the result is a time saving of more than one minute per workpiece - both during welding and in post-processing.
