Chip off the slag with a welding hammer, and then use a 36-grit grinding wheel to knock the beads down to the surrounding metal. To ensure a flat, flush surface, move the grinder along the weld ...

Researchers have identified a welding technique that can be used to join composite metal foam (CMF) components together without impairing the properties that make CMF desirable. CMFs hold promise ...

The typical images of welding—a robotic arm burping sparks or a masked Jesse James hovering over a glowing metal puddle—don’t apply to friction stir welding (FSW).
