Claim:
1. An apparatus for marking a metal surface, comprising: a bed for an object comprising a metal surface; a cover forming an airtight space over the bed; a laser marking unit capable of forming a laser beam onto the metal surface; a gas unit for controlling the atmosphere of the space under the cover; a coating unit for producing a coating on the metal surface; a temperature control unit for controlling the temperature of the space under the cover; a communication interface; at least one processor; and at least one memory including computer program code, wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus at least to: receive from a remote computer via Internet using the communication interface control data comprising parameters to create a pattern on the metal surface; control the gas unit to produce an atmosphere in space under the cover on the basis of the parameters; control the temperature control unit to produce a temperature in one or more time intervals in space under the cover on the basis of the parameters, the temperature being independently controlled during each interval; control the focus and bandwidth of the laser marking unit on the basis of the parameters to produce the pattern on the metal surface; and control the coating unit on the basis of the parameters to produce a coating on the metal surface.
