Metal has been worked by humans for thousands of years. Over time, the techniques and technology used to produce and shape metal goods have been driven by the innovations of science and technology.
Before we dive into some of the technical processes available for welding metal together, let’s first take a moment to define a weld. A weld is a fabrication process that joins materials, usually metals or thermoplastics, by fusion. Fusing materials is distinctly different than other kinds of lower temperature metal-joining techniques such as soldering, which do not melt the base metal.
Metal welding is the fusing of two pieces of metal to create one solid continuous piece. All welders work on the same principle: A gas torch or electric welder is used to generate precisely directed heat to melt material, and a filler material is introduced by the operator to complete the fusion.
As these processes became more accessible, we’ve come so far that you – yes YOU! – can learn how to weld easily.
