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.
