ANALYSIS OF THERMAL STRESSES AND METAL MOVEMENTS OF WELDMENTS: A BASIC STUDY TOWARD COMPUTER-AIDED ANALYSIS AND CONTROL OF WELDED STRUCTURES

This paper discusses how computers can be used to analyze and control distortion of welded structures. Part 1 discusses computer simulation of thermal stresses and metal movement during welding. A brief presentation is made of results of analtyical experimental studies conducted at M.I.T. during the past several years. In the current study, measurements were made of transient temperatures, thermal strains, and distortion during welding along the edge of a strip in an aluminum alloy. Residual stresses also were measured. Experimental results were compared with analytical predictions. Possible uses of computer simulation to solve some practical problems are discussed. Part 2 discusses a parametric study on out-of-plane distortion of a welded panel structure and its effects on buckling strength. A system of computer programs has been developed to study the effects on distortion of various parameters, including plate thickness, stiffener spacing, and weld size.
