3. 2. The orbital welding heads

The PS power sources support most of the Polysoude
orbital welding heads.

3. 2. 1. The open welding heads

• MU IV type (Fig.3.3) for standard or special ap-
plications. Modular design. Weldhead designs to
weld pipes, butt joint type, with or without fi ller
wire.
• Polycar welding carriage to weld large diameter
pipes.

3. 2. 2. The closed chamber welding heads

• MW (Fig.3.4) when high production rates are
required. High duty cycle due to water cooling.
Adaption kits for welding of accessories (elbows,
fl anges, valves, connections, etc.) available.
• Sentry UHP (Fig.3.5) for the demands of high pu-
rity industries. Welding head with closed chamber
designs for the welding of thin pipes, butt joint
type, close square prepared without fi ller wire. It
ensures high quality welds and its compact design
allows to use it in area with restricted access.
• HD when the access to the weld area is reduced.
• K to answer the demand of a very reliable shield-
ing gas protection.
