Repairing a genuine draft

摘要

When the 150-year old Milwaukee-based Miller Brewing Company needed assistance with its extensive brew kettle repair project, the company called Pro Engineering & Manufacturing Inc. (www.prowm.com/). Pro Engineering & Manufacturing has extensive experience in fabricating stainless steel and aluminum products for the beverage, food, material handling and construction industries. Miller Brewing's project was a particularly unique and difficult welding application. It involved repairing damaged copper and stainless steel joints in its six massive brew kettles. Over a period of time, mechanical, chemical and electrolytic erosion degraded the copper and stainless steel interface where the brew kettles' side-walls and domes meet. In certain areas of the brew kettles, the original copper weld used to bond the stainless steel dome to the copper kettle was showing serious signs of wear.
