Welding never spreads any structure. It will always shrink on cooling. Prestressing will probably be the best help with proper support. There should be no doubt if the car is supported only at the very ends it will sag. The longer it sets the more it will sag. Even roof trusses sag over many years and the 914 is not a truss design unless it has a cage.
When it sets on it's suspension points they are much closer than the bumper mounts so some of the weight of the body is not involved in the gravitational pull. If a rotisserie is used along with the door gap supports maybe a support along the bottom of the long to the floor of the shop would help but the welding process is the real answer to the shrinking. I know fg is not the same but my friend that does early vettes has several ladder supports that bolt in all the body mounts to keep their bodies from sagging when they are on a rotisserie. A lot of the problem is there is no roof on the 914. My other friend a fabricator for his entire life knows how much to open a 90 on just two legs of tubing, on different materials, to get them close to 90 when he's through welding the inside of the corner. SS pulls the worst. Usually he gets really close but sometimes he will need a spreader. If he can use a jig he will tack all the inside sides of a square then weld the sides and outside then last weld the inside. Working on all four corners equally. All while it's clamped solidly. I guess along with speed it is more obvious why the mfg. used spot welds instead of seam welding. |
