It has been recognized that repair welding takes an important role in the long term, safe operation of pressure equipment. Responding to the needs in petroleum and chemical industries, the Japan Welding Engineering Society (JWES) published Guideline for repair welding of pressure equipment at 2009. This paper describes the key points of repair welding for heat resistance alloy and non-ferrous metals such as Nickel, Copper, Titanium and their alloys, based on JWES’s guidelines. Before implementing repair welding, it is important to understand the features of damaged materials, because these materials have been used at severe environment in plants.
