ABSTRACT:
In a method of cleaning metal surfaces to be welded together, at least one jet carrying particles of solid carbon dioxide is caused to come into contact with the surfaces, where the solid carbon dioxide is allowed to sublime at the surfaces. The jet is formed by passing a stream of pressurised liquid carbon dioxide through a nozzle under pressure.
