Exhaust systems
Catalytic converters
The robotic welding of catalytic convertors with ferritic stainless metal cored wire Arcaloy 409Ti 1.2mm in octagonal Marathon Pacs. The welding productivity in the production of catalytic convertors can increase by as much as 30% by the use of ferritic stainless metal-cored wire from ESAB MarathonPac, instead of the commonly applied 1.0mm solid wires. Arcaloy 409Ti metal-cored wires are welded in the spray arc mode, in Ar/2%O2 shielding gas, enabling the use of cheaper non-pulsed inverters. At 300A welding current, they yield a deposition rate of approximately 7.8 kg/h. Excellent wetting characteristics and spatter-free welding make this product specifically recommended for the welding of exhaust systems.

Metal-cored wires for ferritic stainless steel exhaust systems
The use of metal-cored wires for welding exhaust systems in ferritic stainless steel exhaust system components replacing MAG solid wire. In the USA, ferritic stainless steels are increasingly used for exhaust systems to provide increased life cycles; a trend in material selection that is coming over to Europe as well. Matching composition metal-cored wires, available from ESAB, provide a productive alternative to solid wires for the most commonly used stainless steel grades. Types for austenitic stainless grades are included. Several automotive applications are highlighted. The article was published in Svetsaren, our customer magazine, issue 1/2000.

Mufflers
Welding of after-market mufflers with metal-cored wire OK 14.13 1.2mm in octagonal 475kg MarathonPac's. OK 14.13 1.2mm metal cored wires give the advantage to be more tolerant for mismatches and to have a higher deposition rate than 1.0 mm diameter solid wire.
