Welding Vs Beam. Pattern A was to weld the cover plate to lower flange of the test specimen where pattern B was to weld the plate to the upper and lower flanges. In both cases the energy of the electrons or photons is turned into heat energy when they impinge upon the surface of the metal.
A good weld will provide as much or more strength as non-welded segments beam. Electron beam welding is a fusion welding process in which a beam of high-velocity electrons is applied to the material and thus welding is done. Pattern A was to weld the cover plate to lower flange of the test specimen where pattern B was to weld the plate to the upper and lower flanges.
Let us have a deep insight into the difference between both of welding process.
In terms of operating costs EB welding has clear advantages over laser welding because the specific consumption of gases energy and cooling has been proven to be significantly higher. Since the heating of the material starts on the surface and then flows down into the material the penetration of a laser welder and the corresponding depth of the weld is typically less that that of an electron beam welder the beam of which actually penetrates the material. When welding dissimilar materials its good to note that different materials weld better with laser beam welding while others respond better to EB welding.
