Interesting Engineering Fact – Welding

Welding is a fabrication process, joining materials together by liquefying the places where they are to be bonded, coalescing these liquids, and allowing the coalesced liquid to solidify. First, where the two materials meet is melted, often adding a filler material, forming a molten material pool. At the end of this process the two materials have become one continuous solid, and if the weld has been made correctly, it is as strong as the original workpieces.

In around 3000BC, the Egyptians heated iron ore in a charcoal fire, reducing it to direct reduced iron or sponge iron. Then, the particles were welded together by hammering. This “pressure” or “solid-phase” welding is the first recording of welding.

Fast forward to the 1800s, when the electric arc and acetylene discovery created the stage for modern welding. In 1887, a patent for the first welding “machine” was awarded to Stanislaw Olszewski and Nikolay Bernardos. Their patent for welding lead plates together detailed an early electrode holder, regarded as the birth of carbon arc welding.

At Newland we provided specialised fabrication services for jobbing and production runs of small to medium sized components and assemblies. Our skilled fabricators and welders work to close tolerances with the assistance of high accuracy jigging tables and fixtures.

We fabricate from a wide range of materials including steel, aluminium, stainless steel, and metal alloys. Our fabrication services are further enhanced through our in-house engineering and design, machining, hydraulic and mechanical departments, and metal finishing services including in house blasting and painting.
