400 400 Jok N 330 375 j central support diameter = 70mm x 5.5 mm wall thickness i) Using 270 electrodes, find the required weld length to attach central support to base ii) Comparing weld size to the wall thickness of tube, where is the likely point of failure in the connection.

Please urgent... Thank you advance

Two steel plates, each 400mm wide and 12mm thick, are to be joined together by a lap splice (single). The electrode to be used for the weld has a nominal tensile strength of 550Mpa. Determine the following:a. the maximum weld size that can be usedb. effective net area of the fillet weld using the maximum weld size allowed by the manualc. the maximum load that can be resisted by the weld using the maximum weld size allowed by the manual.
