Method for constructing impingement/effusion cooling features in a component of a combustion turbine engine is provided. A pocketmay be arranged between an outer walland an inner wallof the component. A lasing deviceallows drilling through the component to form an effusion hole. The lasing device further allows welding closed an openingformed at outer wallof the component during the drilling with the lasing device through the component. Lasing devicefurther allows drilling through outer wallof the component to form an impingement holefor the impingement/effusion cooling feature. The proposed methodology in a multi-panel arrangement, for example, eliminates a need of having to pre-drill such holes in individual panels prior to the bonding and forming of the component, which overcomes various drawbacks commonly associated with such pre-drilling.
