CMT – Cold Metal Transfer
Outstanding results on all materials with an extremely stable arc.
An arc in the lower power range with a consumable electrode. The short circuiting arc is initiated by the wire electrode briefly touching the work-piece. This creates a high, rapidly increasing current that induces a magnetic phenomenon known as the pinch effect. The pinch effect causes the wire to neck down, and the increased current in the reduced cross section of the wire cuts the droplet from the wire. After the short-circuit bridge is broken, the arc reignites, and the process repeats . A short circuiting arc can be performed in practically any position.
A combination of CMT and pulse cycles for particularly difficult weld seams and demanding requirements.
Fronius Perfect Welding is expanding its product range for resistance spot welding. The advantages are minimal downtimes, optimal accessibility to components and high productivity when joining aluminium.
The plasma welding process is very similar to the TIG welding process, but has a number of key advantages. These make it an attractive alternative to laser welding, which demands high quality standards – in particular for sheets and other components with a thickness of up to 8 mm.
