Abstract
A method of brazing, with the use of a plasma forming device (1) having a non-consumable electrode (2), comprises the following steps of operation. A first gas is supplied to said plasma forming device (1). A plasma flow is formed of said first gas by applying a voltage between said electrode (2) and an electrical terminal (7). The plasma flow is directed towards a work piece (7). Braze material (10) to be melted by said plasma flow is provided. Furthermore, a second gas may be supplied for shielding said plasma flow from the surrounding atmosphere. At least one of said first and second gas comprises a principal inert component including at least argon and in a minor amount an active component.
