ANALYSIS AND CONTROL OF DISTORTION IN WELDED ALUMINUM STRUCTURES

Results of recent investigations at M.I.T. on the subject of analysis and control of distortion in welded aluminum structures are summarized. After a brief overview of the distortion problem as a whole, three kinds of welding distortion are analyzed: longitudinal bending distortion, out-of-plane angular distortion, and buckling distortion. Experimental results are presented and compared with predictions obtained by computer programs developed at M.I.T. Methods for the control of these kinds of distortion are proposed. They include the elastic prestraining method, the differential heating methods, and the application of tensile stresses during welding. It is concluded that the computer programs developed so far can, with proper modifications, be very useful to designers and fabricators in dealing with the distortion problem. They can be part of an integrated system capable of determining the optimum values for the parameters of the problem, taking into account structural hydrodynamics and fabrication considerations.
