Overlay Welding
Geo-Tech has proven and perfected a new
continuous submerged Arc Overlay Process with
approved A.S.M.E. registered procedures.
In-situ application of weld overlay to the
internal surface can be used to:
- Build up corroded areas to the original
thickness or to increase the corrosion allowance
- Apply a corrosion-resistant material to the
internal surface

Application Method
Weld Overlay is applied using a submerged arc
procedure, utilizing two weld heads simultaneously.
Components for this equipment are sized to pass
through a 20" manway, after-which they are
assembled in the vessel. A Digester, (13'-3"
dia. x 53'-11" high) was recently completed on
Vancouver Island, however, there are no diameter or
height limitations.
Third party inspection is engaged for continuous
monitoring during the welding process. Metallurgical
quality is verified by using a nuclear analyzer
(Texas Instruments). See
Appendix 1
Portable Machining
Geo-Tech specializes in design and manufacture of
custom machines for metal removal in-situ. Using
pneumatic or hydraulic power sources, we have
successfully accomplished some unique projects such
as:
- Removing the "scallops" from a tub
handle inside a recovery boiler
- Machining a rail supporting a 700-ton
astrophysical observation dome on a telescope in
Hawaii. This was machined to an accuracy of
0.020: in 110' diameter
- We have 25 H.P. hydraulic sources to drive
equipment, cutting-heads or to rotate vessels
We have
the experience and in-house skills to design and
develop a machine to take care of your needs.
