Automated Pipe Cladding System
The installation is intended for welding components of aircraft and space engines. The installation is a system consisting of two workstations. Each workstation is equipped with two manipulators and a robot connected to welding units. A fume extraction system is installed above both workstations, providing ventilation throughout the entire operation of the system. Both robots are equipped with a laser seam tracking system. One of the welding units is equipped with the Cold Metal Transfer (CMT) function, enabling the welding of thin sheet metal.

CMT (Cold Metal Transfer) Welding Process
The CMT (Cold Metal Transfer) process enables "cold" metal transfer during welding (compared to the conventional MIG/MAG process). Upon the first detection of a short circuit, the power source reduces the welding current to the minimum allowable value; droplet detachment occurs due to the reverse (mechanical) movement of the welding wire. Metal transfer occurs at low current values, ensuring minimal heat input.
During the arc burning phase, the filler material is transferred into the weld pool.
When the filler material is immersed in the pool, the arc extinguishes and the welding current decreases.
Reverse wire movement promotes droplet detachment during the short circuit. The short-circuit current is maintained at a low level.
The wire movement direction changes, and the process starts again.
