Metalcasting Helps Haiti


There’s been no shortage of media coverage of the earthquake that recently rocked Haiti, but when the news involves metalcast- ing, our attentions are always aroused. The metalcasting process recently helped Alfred Univ., Alfred, N.Y., earn more than $5,000 for the Haitian relief effort. According to an article in the school’s newspaper, the Alfred Univ. Foundry Guild sold $10 sand molds to locals, allowed them to scratch designs into the molds and poured them off, producing original sculptures for the would-be philan- thropists. The funds, augmented by a silent auction of artwork, were donated to a Haitian family with ties to the school and Doc- tors Without Borders. The industry that has been rebuilding things for hundreds of years is now helping to rebuild a nation.


How Much Welding in Steel Casting Is Too Much? The following question and answer


recently appeared on the Metal Casting De- sign & Purchasing LinkedIn message board: “It is not uncommon for steel casting


customers to ask how much welding is ac- ceptable to meet overall requirements on weldable class-b carbon steel (WCB). The material is easily weldable and, when stress relieved, no detrimental performance is- sues with extensive welding arise. So, from a technical and performance standpoint, no limit to the amount of welding that may be done to a WCB casting exists. The specifi cation ASTM A216 requires


the use of a qualifi ed weld procedure and welders. The standard requires that the cavity meet the same quality standards as the casting prior to the weld. Major welds

based on depth or size require stress relief or post weld heat treatment. Users can reserve the right to approve major welds by citing standard A703 S12.1. Commercially, welding after receipt by


the customer is undesirable. Measures of welding volumes in production practices are not common. In the metalcasting facility, welding typically runs about 12- 15 lbs./ton but varies based on customer requirements, part size, casting design and process practices. Any particular casting weld requirement is purely a commercial judgment about whether a casting can be made to conform by welding or if it should be scrapped.” —Raymond Monroe, Steel Founders’ So- ciety of America Executive Vice President
