Cold metal transfer solves welding
problem
The MACH 2008 event allows TPS - Fronius to showcase a wide range of equipment used in industry, from Construction to Chemicals, from Manufacturing to Offshore Engineering
With 400 active patents, Fronius has recently launched several innovative welding solutions One is its revolutionary cold metal transfer (CMT) process, which is successfully resolving long-standing problems in the welding industry

Cleaning welding torches
The innovative electro-magnetic way to clean welding torches has a positive effect with regard to quality and economy: non-contact and save money at the same time.
The name "Cold Metal Transfer" hints at a crucial difference from the conventional GMA (gas metal arc) process: significantly less heat is applied to the metals to be joined.
There are materials and applications that cannot withstand the constant heat of a welding process.
In order to avoid weld-pool drop-through, to be spatter-free, and to be amenable to metallurgical joining, they need lower temperatures.
With CMT, this is now possible.
CMT enables the welding of materials as thin as 0.3mm and of widely different gauges, with minimal spatter and distortion due to the low heat input of the process.
The lower heat input of the "cold" process brings with it significant advantages: significantly less thermal delay and rework.
CMT can also now offer the innovative ability to join aluminium and steel.
When combined with a pulsed arc, the heat input, the penetration and also the weld seam geometry can be varied from the pure "cold" CMT-process up to the relatively "hot" pulsed arc process.
The combination of the CMT-process with the pulsed arc process also supports the excellent gap bridgability and leads to further enhancement in the welding speed.
The special features of CMT produce faster welding speed, higher productivity and an impressive ability to bridge gaps compared with conventional arc-welding processes.
It gives uniform, spatter-free seams, even on light-gauge sheeting with gaps more than 1mm wide.
With CMT it is possible to replace TIG manual applications with mechanised MIG applications.
Indeed, CMT is just as suited to the small firm with one automated welding workstation as it is for batch production in large-scale industry.
With its high degree of process flexibility, CMT offers benefits in respect to quality and economy.
With the spatter-free CMT process, Fronius has opened up a new chapter in the history of welding.
