Coreweld 89

Coreweld 89

Coreweld 89 is a new metal cored wire for the welding of high strength steel with a minimum yield strength of 900 MPa. These steels are increasingly used to create lighter, higher performance structures with good overall cost effectiveness, together with lower environmental impacts. When welding high strength steel, it is very important to use low diffusible hydrogen welding consumables in order to avoid hydrogen induced cold cracking. Coreweld 89 falls into this area, meeting the strict AWS H4 and EN ISO H5 requirements. Coreweld 89 provides excellent sub-zero toughness down to -40ºC and low diffusible hydrogen levels, using shielding gas in the range Ar/5-25% CO2 (EN ISO 14175 M20 and M21). Coreweld 89 has all beneficial features attributed to ESAB metal cored wires including a smooth arc transfer which produces minimal spatter and silica level on the weld metal surface. With the resulting wide arc the risk of lack of fusion defects is significantly reduced which can be a problem when using the GMAW process. Typical applications are found in the manual, mechanized or robotic welding of components such as: • Crane arms and other lifting equipment • Booms for forest machinery • Chassis and bodywork of commercial vehicles • Load support and fastening equipment • Load handling equipment • Feeding and unloading hoppers • Containers
