Panasonic Robot & Welding, a Business Division of Panasonic Industry Europe, has recently come out with their latest technology, Super Active Wire Feed Process (S-AWP).

Akira Saito, Product Marketing Manager: “This innovative process combines two aspects that were formerly considered impossible to bring together. The first important aspect is the wall of critical amperage. S-AWP is able to maintain stable short arc transfer to much higher amperage than critical amperage, where it starts to globular. The second aspect is the wall of humping. S-AWP is also able to stabilize the arc from humping, even when welding at high speed. This is absolutely new in the market.”

Utilizing a reciprocating wire feed in combination with a continuously monitored current waveform to control material transfer throughout the short arc circuit transfer cycle, it is now possible to reduce welding spatter and material distortion to a minimum. This also ensures a flawless weld appearance, especially when using thinner materials. It uses a reduced heat input and increased material deposition during the welding process. The number of short circuits for material transfer during welding have been increased significantly. This also reduces both the transfer droplet size and spatter. In addition, the disturbances caused by post-vibrations in the weld pool are almost completely eliminated. Super Active now possesses a 200 W wire feed motor and a direct drive to the wire feed rollers which increases wire feed accuracy. Reciprocation speed can be higher than 150 times per second. A forced air cooling system built into the welding torch has allowed us to increase the performance envelope giving a 100 % duty cycle of 245A using mix gas or 310A using CO2.

Regardless of the material to be welded, whether aluminium MIG continuous or stitch welding by using the company’s tailored aluminium software, utilizing steel MAG with HBC (Heat Balance Control) is suited for welding the thinner high strength steels used in the automobile industry. Zi-Tech technology for the low spatter/porosity welding of zinc plated steel, or austenitic/ferritic stainless steel welding with greatly reduced distortion, gives a variety of possibilities for all welding needs.
