I have a large piece of 6061 aluminum that has a 1 inch hole in it (oops) and the material will finish at about .430 thick. My thought is to bore the hole and make a over size plug, (press fit) and have it welded on the inside of the cover. After I am finished machining it, the outside of this motorcycle cover will get chrome plated. The question is, should I also weld the side that will get chrome plating also? Will the welding affect chrome plating? Thanks:
