摘要：

The paper deals with multiple-wire submerged-arc welding and cladding with metal-powder addition. Three different ways of supplying the metal powder to the welding area are described and shown schematically. It was found that the use of metal powder will increase the deposition rate, and the welding-arc efficiency and reduce the shielding-flux consumption. A suitable device pen-nits submerged-arc welding and cladding with metal-powder addition. The process is primarily meant for the cladding of worn surfaces or the production of surfaces with certain characteristics (corrosion or wear resistance). By using the metal-powder addition it is possible to alloy a weld or a cladding with optional chemical elements. (C) 2002 Elsevier Science B.V. All rights reserved.
