Alweld uses TIG (Tungsten Inert Gas) welding on all external welds.
The center keel on all of Alweld’s boats is a strong, complete TIG weld forming the two pieces together. No extrusions are used to keep the hull together.
TIG Welding produces a leak-proof seam, which MIG welding cannot. And since TIG welding creates a narrow heat affected zone, stress, cracks and distortion are virtually eliminated.
On external welds such as the corner brackets and nose caps, TIG welds create a smooth, strong seam.
The diagrams below illustrate the differences between the Center Keel Construction on Alweld boats (a TIG weld, like all Alweld external welds) and those of many other manufacturers - A Centre Keel extrusion.
Like all aspect of Alweld's boat construction, our guiding principle is to build boats of the highest quality.
