Mechanical processing (e.g. turning, milling, punching, lasering) produces edges, splinters, or fraying on the workpiece due to the displacement of material. These are referred to as burrs. Steel, aluminum, castings, and forgings are the main materials being deburred, but burrs also occur on wood or plastic parts.
When it comes to deburring engine parts, housings, and pneumatic and hydraulic parts that have many internal bores, cross bores, threads, O-ring recesses, etc., there are different tools for processing depending on the application.
Welding is used in many industries. In tank and container construction, vehicle superstructures, wagon construction, shipyards, pipeline construction - stable, permanent joints are essential everywhere. And this can only be achieved if the work is done cleanly. A botched seam can have far-reaching consequences and is relevant to safety.
