Brass for controlling the welding parameters in order to weld two metallic workpieces

摘要

Regulating the welding parameters for producing a weld joint between two metal components (1,2) by filling a chamfer (3) involves determining for each of the filling layers (6, 6n-1, 6n) in the chamfer (3) the following parameters: (a) the width of the base (Lic) of the layer (6n) between the first and second edges (1a,2a) of the chamfer; (b) the number of weld passes needed to produce the layer (6n); (c) a real remaining width (Lr) for the layer (6n) by subtracting from the base width (Lic) a predetermined fixed value (Lif) corresponding to the optimal width of the final weld ribbon in contact with the second edge (2a) of the layer (6n); (d) an initial value (Lin) for the remaining width; (e) a relationship (R) between the real remaining width (Lr) and the initial value (Lin) of the remaining width is calculated; and (f) the speed of advance of the welding head during successive passes for the production of the layer (6n) and the staggering of the welding head in the direction transverse to the chamfer (3) between two successive passes.
