From the Fronius website -
The “cold” CMT (Cold Metal Transfer) Advanced welding process from Fronius stands for deposition rates that can be exactly adjusted by way of positive and negative process cycles. As the polarity reversal takes place in the short-circuit phase, this joining process ensures the high stability to be expected of cold welding. CMT Advanced also brings further advantages, including targeted heat input, a higher deposition rate with no increase in heat input and minimal distortion. What’s more, it produces very few welding fumes, which improves the working conditions for the welder.
HOW CMT ADVANCED WORKS
The welding process is based on a combination arc with positively and negatively poled CMT cycles. Pole reversal takes place in the short-circuit phase, keeping the arc stable. During the negatively poled phase, the welding process achieves a higher deposition rate and improved gap-bridging ability, whereas the positive cycles are marked by targeted heat input and exact droplet transfer. The wire motion is incorporated into the process.
CMT ADVANCED PULSE: JOINING HIGH-STRENGTH STEELS WITH LOW HEAT INPUT
While the positive cycles are alternated with the negative cycles during CMT Advanced, the CMT Advanced Pulse welding process combines CMT cycles with a negative electrode polarity and a pulse phase with positive polarity. The process achieves a higher deposition rate during the negatively poled phase with lower heat input. Pole reversal to the positively poled pulsing cycles takes place in the short circuit. As well as higher heat input, the pulse phase gives the user the advantage of non-short-circuiting droplet transfer. The relationship between the positive and negative process cycles is freely selectable. CMT Advanced Pulse makes it possible to join high-strength steels with a sufficiently high deposition rate yet with low heat input.
HIGHLY VERSATILE
CMT Advanced guarantees a very high gap-bridging ability when welding different materials such as steel, chrome-nickel and aluminium. The user benefits from the following advantages:
Light and ultra-light-gauge sheets can be joined with high gap-bridging ability and high-strength steels can be joined with minimal heat input
Minimal dilution is possible in overlay welding
Root welding can be performed without pool support
A lower heat input is required for dissimilar material joints, such as steel and aluminium, and a higher deposition rate is achieved
High-strength and ultra-strong steels can be brazed
Extremely low heat input and an exceptionally stable arc set CMT apart from conventional MIG/MAG welding. The Fronius CMT (Cold Metal Transfer) welding process allows users to achieve optimum results when joining different materials, for example steel and aluminum.
A WEALTH OF WELDING BENEFITS FOR THE USER
The digital process control detects a short circuit and then helps to detach the droplet by retracting the wire: during welding, the wire moves forward and is pulled back again as soon as the short circuit occurs. As a result, the arc only introduces any heat for a very brief period during the arc-burning phase. The short circuit is controlled and the current is kept low, resulting in a spatter-free material transfer. The arc length is detected and adjusted mechanically. The arc remains stable, no matter what the surface of the workpiece is like or how fast the user welds. This means CMT can be used everywhere and in every position.
DIVERSE, HIGHLY INTERESTING AREAS OF APPLICATION
CMT welding is ideal for joining steel and aluminium, as the galvanised steel plate is wetted by this braze-welded joint, while the aluminium melts. Furthermore, the CMT welding process is also suited to the virtually spatter-free brazing of hot-galvanised and electrolytically galvanised sheets with a welding wire made from a copper-silicon alloy. Minimal distortion of the galvanised sheet occurs and the light-gauge welding of aluminium sheets (from 0.3 millimetres) is also possible, whereby the low heat input eliminates the need for pool support. Equally impressive results are achieved when welding stainless steels and magnesium.
