You’d think writing for Hackaday means we probably don’t get surprised very often by projects… but then we see something we never thought was possible — in this case, the linear friction welding of ...

Friction stir spot welding (FSSW) has shown promising potential for joining sheets and other geometries of metals as well as polymers. For thermoplastic materials, especially carbon black reinforced ...

We are providing an unedited version of this manuscript to give early access to its findings. Before final publication, the manuscript will undergo further editing. Please note there may be errors ...

Linear friction welding welds materials together using heat from friction. After placing two materials into a welding machine they are then pushed tightly together. One of the two materials moves ...

This is a close-up view of porosity in a TIG weld. We will examine some of the causes for weld porosity and ways to prevent it. Q.When I TIG-weld a patch panel into an old car and then grind the weld ...
