Welding Pros

My hood is tearing itself apart at the hinge , the part of the underside support that holds the piece with the threaded holes for the mounting bolts is tears at the rounded corner below the bolt closest to the fire wall , is it possible to Tig the tears without cooking the paint off the outer skin ? I was thinking maybe holding a bag of ice on it , the weld would be a couple of inched below the outer skin on the brace . I'll try to draw a diagram and add it here later . scrap that I'll take a pic and post it tomorrow can't draw for dookie
