Cutters and welders are two types of metalworkers. Welders join pieces of metal together by melting them and fusing them together. Cutters cut pieces of metal to size with a tool like a saw or a laser. Welders tend to work with thicker pieces of metal, while cutters can work with thinner pieces. Welders also typically have more experience and skills than cutters.

Cutters are machines that use a high-pressure stream of water to cut through hard materials like metal or concrete. Welders, on the other hand, use heat and/or pressure to join two pieces of metal together.
