Hi Tech for all alloy boat welding and modifications.

Alloy fabrication for all marine

Item: Alloy Buoys

Make: Dive Buoys


Alloy buoys with pitting and cracks, causing submersion and worn anodes


Buoys were sandblasted back to bare. Alloy reweld to cracks and corrosion spots, replaced zinc anodes, pressure tested and re-powder coated.

Hi Tech for all Alloy compoent repair

Remove vac line fitting 1:
Just another part rejuvenated with welding a large rub
through mark on a alloy pipe off a intake line.

Remove vac line fitting :as seen in this picture this pipe was badly cracked and we where able to clean and prep area reweld and grind back flush surface.

Weld flange to pipe: Hi-techs welding capabilities will allow us to add/modify any alloy pipe work and pressure test.

Weld crack in sump: A very common problem these days is alloy sumps on both cars and trucks cracking from castings breaking down and getting metal fatigue or caused by impact damage.

Weld crack in sump1: Hi-Tech radiators can also strengthen the weld by cutting a gauge or v shape into the material and then spray a leak detection on weld .if any spray comes through we will know its leaking so all leak detection can be covered no matter how difficult the item.

Header Tank Replacement

Century1 = This is a a newly fabricated alloy header tank off a freightliner century c120 truck where original was plastic and only lasting average period off 12 months which is far from the life expectancy off the newly fabricated alloy tank with a life expectancy off 5+ years.

Century 89kb= As seen in this picture the alloy tank has been made with also a great finish and no major 90 degree folds which can act as weak points this header tank has also had extra internal supports put in to allow for thermal expansion.

Eagle = This header tank is an alloy copy off an original plastic header tank off a international eagle where the o/e plastic tanks are cracking prematurely from heat under the bonnet and vibration cracking mounting areas so pay the extra and get what you expect from one off hi-techs perfectly hand fabricated truck header tanks.
