Abstract

Compared to welding a new fabrication in a clean shop, the repair welding of vessels, tanks, piping pumps, etc. on-site presents special challenges, especially with stainless steels and nickel alloys.  The presentation will look at a few of the more major considerations and how to think about weld repairs for the different families and alloys of stainless steel and nickel alloys.  After the first evaluation, which is the most important issue of safety, the second evaluation is whether the equipment can be weld repaired.  If it can be repaired, some tips on how to weld repair will be given.

Gary Coates

Gary is Technical Manager for the Nickel Institute, Toronto, Canada.

He has worked in the stainless steel and nickel alloys industry for 45 years, the last 21 with the Nickel Institute. Welding has always been of major interest, as often welding is the weakest link in fabrication. He has worked with many different end use industries and with fabricators to ensure they have access to proper welding information. He is actively involved with many professional societies, including the American Welding Society, and is an active contributor to their Welding Forum. He has made many presentations worldwide on all aspects of use of stainless steel and nickel alloys.
