Bohler EMK 6-Ultra Solid Wire Mild Steel Welding Wire
Bohler EMK 6- Ultra is a premium coated copper coated solid wire for high efficiency mig/mag welding of non alloy and low alloy structural steels. It belongs to the specialist EMK Ultra series, which uses advanced production technologies to optimise wire feeding and arc stability, lowering post-weld cleaning times. It is widely utilised across demanding sectors requiring robust mechanical strength and reliable weld metal toughness, including:
- Structural steel engineering and general metal fabrication.
- Automotive components and heavy transportation manufacturing.
- Shipbuilding and maritime structures.
- Boiler, tank, pressure vessel, and industrial piping systems
The elevated silicon and manganese levels allow the wire to successfully handle slightly oxidised or contaminated surface metals while minimising porosity. Engineered to minimise CO formation, produce exceptionally low spatter, and ensure an aesthetic, smooth weld bead appearance. The tightly controlled manufacturing process guarantees smooth wire feeding through manual torches or fully automated robotic setups.
