dc.description.abstract | Modern era utilizes novel technologies. Hot wire gas tungsten arc welding process is an emerging technique with efficient performance. However this process is mostly employed only for cladding and coating process which as a result got very least importance in welding of materials. In conventional welding process, an arc is used to melt the base metal; accordingly the process parameters are arc voltage, electrode current and traverse speed of torch. On the contrary, in hot wire gas tungsten arc welding process two circuits supply energy required to weld the metals. The primary circuit provides primary current to tungsten electrode for heating the base metal, and secondary circuit supplies to feeder mechanism. The filler wire passing from feeder mechanism gets heated and supplied to the weld pool. The filler wire is preheated; which results in less consumption of power from the primary circuit. The weld deposition rate for it is high when compared to the conventional process. Hot wire gas tungsten arc welding process is preferably used for welding metals in high temperature applications. The major parameter that influence the welding are electrode current, hot wire current and feed rate of the filler material. Commercially pure nickel known as Ni-200 is used in high temperature corrosive environments. Due to its inherent physical property, it is used in caustic environment, food processing industries and in panel coil heat exchangers. Inculcation of nickel has increased now a day in all areas. In this commenced work an effort is taken to establish a parametric window for welding the commercially pure nickel tubes. In order to establish the parametric window, lot of trials or experimentation is essential. In consideration of the resource availability and cost, statistical tool is employed to simplify the work and avoid number of trial welds newline | |
