TENSILE STRENGTH ANALYSIS OF LAP WELDED JOINT OF SIMILAR PLATES WITH F.E.A.

Welding�,the simple process and excellent strength makes it useful in manufacturing of steel structures like ships,ocean structures,automobile,aircraft and bridges. The challenges associated with welding and welded joints are improved tensile strength of welding under variable environmental and working conditions. The parametric study has been carried out,overlap length and gap size are selected as parameters to be varied during experimentation. The range of parameters is decided by referring literature. Design and validation of fixture is carried out for testing purpose. Specimens are prepared with greater accuracy and tests were carried out using UTM. The results obtained from experimentation are compared with result obtained from simulation. It is re commended to keep overlap length 25 mm for 5 mm thick plate with minimum gap size. This will give maximum tensile strength
