The object of the invention is a method for adjusting a welding parameter of a welding device, which method comprises steps, in which a desired cooling behaviour is predefined for the welding joint, information about the desired cooling behaviour of the welding joint is given to the welding device (100) by giving to the welding device (100) a cooling time t, an amount of heat input Qset, or material information about the material to be welded, after which the welding device (100), based on the given information and on preliminary information given to the welding device (100) in advance, determines and adjusts the values of welding parameters to be used in the welding in order to achieve the desired cooling behaviour of the welding joint, and that the welding device (100) either determines the actual heat input during welding Qact and, by adjusting at least one welding parameter, sets the actual heat input Qact to correspond, within the adjustment range, to the heat input Qset determined through the cooling time t or the material information, or to a given amount of heat input Qset, or that the welding device (100) calculates and monitors the power guide value Pset based on the heat input Qset, the measured or given travel speed V of the welding gun (103), and the thermal efficiency factor k, calculates and monitors the actual power Pact, and, by adjusting at least one welding parameter, sets the actual power Pact to correspond, within the adjustment range, to the power guide value Pset, or, by adjusting at least one welding parameter, sets the power guide value Pset to correspond, within the adjustment range, to the actual power Pact. |
