Recently companies which do not use the heavy metals such as lead, chrome, mercury to the electronic goods and alternate the materials environment-friendly are increasing. In advanced country, lead-free solder without lead is developed and soldering process almost disappeared. The lead-free solder is environment-friendly but is expensive and lack of tack and durability than lead, the improvement is necessary. To solve this problem, the welding process that uses TIG welding and the welding technology between different kind metals for lead-in wire of room lamp and base department was developed. To do this, previous room lamp manufacturing process was analysed and which process can be alternate was proposed. And the test for selection of optimal value of TIG welding parameter was done. Finally the lamp aging test and earthquake resistant test was done to check the reliability of welded room lamp.
