Method of manufacturing metal containers
A method of manufacturing a container includes positioning metals plates against one another to define an interior space, filling the interior space with a granular refractory material and welding the seams between the plates to form a fluid tight container.
1. A method of manufacturing a container, the method comprising:
positioning metal plates against one another to define an interior space;
filling the interior space with a granular marble material such that the container is entirely filled with the granular marble material to prevent at least one of weld spatter from adhering to an interior of the container or burrs from being created at one or more seams defined between the metal plates; and
welding the one or more seams between the metal plates, a portion of the granular marble material being in direct contact with the one or more seams during welding.
2. A method as claimed in claim 1 , wherein granules of the granular marble material are rounded.
3. A method as claimed in claim 1 , wherein granules of the granular marble material are angular.
4. A method as claimed in claim 1 , wherein granules of the granular marble material have a diameter in the range from 3 mm to 4 mm.
5. A method as claimed in claim 1 , wherein the metal plates are made from steel.
6. A method as claimed in claim 1 , wherein the metal plates form a fluid tight container.
7. A method as claimed in claim 1 , wherein the container is re-oriented during welding such that the granular marble material contacts the one or more seams.
