ABSTRACT
With advances in material and welding technology, fabrication processes today call for high standards of understanding and workmanship. Equipment made with materials of correct choice and quality and adequate design may fail in service if the workmanship is sacriced during fabrication [1]. It is needless to say that failure of any heat exchanger in service due to bad manufacturing practices, apart from causing loss of production, may cause accidents and damage to the equipment and property. Therefore, in industries where heat exchangers are to be made as per code, it is essential that the product quality be controlled at all stages of its manufacture.
