ABSTRACT:
In having a method of welding together metal components (A,B) a high restraint geometry (as defined in the Specification) the components are urged into abutment and a high energy density weld is effected at a location in said abutment by means such as a focussed laser beam (L). In order to compensate for the high restraint geometry of the components which prevents them from deformation such as to accommodate welding stresses, an additional force (J) is applied, for example by a roller (K), to urge the components together adjacent to the position at which the weld is effected. The method is advantageously employed to form a continuous elongate weld between a plateform and web of a brake shoe.
