AWS Releases New Steel-Welding Specs
Thursday, October 17, 2002
The American Welding Society (AWS) has issued 13 revised Standard Welding Procedure Specifications (SWPS) for welding 10- through 18-gauge galvanized steel, carbon steel and austenitic stainless steel sheetmetal, in the as-welded condition, with or without backing. They outline variables for welding steel using semiautomatic gas-metal-arc welding, shielded-metal-arc welding or manual gas-tungsten welding. Also included are operating conditions necessary to fabricate the weldment.
Each specification, 12 pages long, costs $180 for AWS members and $240 for nonmembers. To see a list of the new specifications or to order, visit www.aws.org
Stelmi To Debut Unique Chrome-Plating Process
Wednesday, October 16, 2002
Stelmi America Inc., Marshall, MI, is set to begin U.S. operations using an advanced, continuous chrome-plating process that company officials claim is new to the North American market, where batch production is typical. In producing long-length hard-chrome-plated steel bars and microfinished steel tubes, the company will perform chrome plating as a continuous process operation performed on traveling bars. Here, the bars translate and rotate one-by-one through a chrome-plating machine that fully encloses the process, without use of open vats or tanks. This method reportedly provides uniformity of plate thickness and enhanced corrosion resistance.
