weld

WELD/weld/

A firm joining of materials, usually by heat or pressure.

She welds two steel plates together to repair the gate.

A protected welder joins two steel plates edge-to-edge, with a small bright arc at their meeting seam and a continuous raised weld bead behind the torch.
Etymology

The older verb well meant “to boil, rise.” Weld developed a metalworking sense of uniting metal by hammering or compression, often after heating had softened it—the connection to today’s heat-based joining.
