Structural Requirement,sverse strength, torsional strength, local strength. Therefore the structural requirement calls for satisfying these four strength considerations and thereby takes care of the effect of service loads.

Plate and Section Forming,thickness, resulting in angular bending of the plate. By applying this bending at the required location, the target shape of the plate can be achieved. This method of line heating can be gainfully utilized using a numerically controlled heating torch to apply the required thermal load to achieve the

Fusion Welding Power Source,sources can provide power in pulses over a broad range of frequencies. These are known as pulsed power sources. The principal metal transfer modes in gas metal arc welding process are short circuiting transfer, globular transfer, spray transfer and Pulsed transfer.

Welding Residual Stress and Distortion, the weld metal and the base metal cool down to the room temperature residual stresses are formed. If some of the external restraints such as clamps or welded lugs are removed, the residual stresses may find partial relief by causing the base metal to further deform.

Distortion Control and Mitigation,stortion mitigation technique known as Thermo-Mechanical Tensioning (TMT). In this method through the use of restraining and tensioning lugs, the tensile residual stress field generated by welding of stiffeners is reduced. This leads to reduction of the balancing compressive stress field.
