ESAB - One solution - one supplier This brochure presents an overview of Both proceses are characterised by a high ESABs product range of strip cladding deposition rate and low dilution. They are consumables. ESAB can offer a complete suitable for surfacing flat and curved objects technical solution including power sour- such as heat exchangers, tubes, tube sheets ces, equipment, strips and fluxes as well as and various pressure vessels. process and metallurgical know-how for strip cladding. Submerged arc welding (SAW) is the more frequently used, but if higher productivity and We supply strip electrodes and suitable restricted dilution rates are required, then fluxes for almost all demanding applications, electroslag welding (ESW) is recommended. for example for the chemical, petrochemical, nuclear and pulp and paper industries and also repair and maintenance. Two cladding processes ESAB can offer the two most productive systems for surfacing large components which are subjected to corrosion or wear. These are submerged arc and electroslag cladding, using a strip electrode. 3 Strip cladding processes Strip feeding Current supply with jaws Liquid slag Soldified slag Flux Wield deposit Base material Figure 2: Submerged arc strip cladding SAW strip cladding slag.
