WELDING SPECIALIST
MarineShaft has the class approval and the equipment to weld
on shafts, rudder stocks, and other components.
RECONDITIONING
BY WELDING
COLD PROCESS
WELDING TECHNIQUES
We can provide you with a fast and professional repair when a rudder stock or
propeller shaft suffers from wear or corrosion. We have the class approved welding certificates to start a repair immediately, reducing the delivey time.
We specialize in new cold process welding techniques enabling us to weld on
high-carbon steel and other components
that does not tolerate conventional welding methods.
Our welders are certified and specially
trained and work with all sorts of carbon
steel, stainless steel, and bronze with different welding types such as:
MICRO WELDING
TIG, MIG, MAG welding, and submerged
arc welding with different types of material.
POST-WELD-HEATTREATMENT (PWHT)
MarineShaft carries out heat treatment of
steel and welded joints at our workshop
or on-site at your choice.
The thermal stress from welding influences the material in the welded joint and
the surrounding areas. We carry out controlled heat treatment before, during, and
after welding and thereby eliminate any
unwanted changes in the structure and
properties of the material.
Our heat treatment is carried out by certified technicians and using class approved
procedures.

Micro welding can repair scratches and
impact marks of several mm on areas that
do not tolerate conventional welding.
With a high current 500-1650 ampere impulse, concentrated in spots of 0.2 mm
per impulse, the filler metal is melted to
the base metal within milliseconds.
Micro welding requires no machining afterwards - only hand finishing. Our equipment is portable and easily taken to any
location.
ROBOTIC WELDING LASER CLADDING
Laser cladding is an efficient and accurate
method that guarantees 100% adhesion
to the base material. By laser cladding,
you can rebuild and prolong the service
life significantly.
Laser cladding is performed with a numerically controlled robot, which gives us
plenty of geometric repair opportunities.
