HBE-70M Mild & Low Alloy Steel Welding Wires for shipbuliding

GB/T10045E500T-1AWS A5.28 E70C-G
Features:HBE-70M is thewire for alkalinity steel welding . Excellent welding craft, smooth arc with low spatter and high depositionrates.
Applications:To be used for flat welding & fillet welding position weld with singer or double wire It has high depositionrates to be wide usedfor shipbuilding ,bridge and steel structure.
Notes:1). To take CO gas as gas-shielded and its purity should be up to 99.8% with flow at 20-25L/min.
2). Keep the electrode extension between 15-25mm.
3). Recommended current (DCEP)Wire to beincontact with positive pole.
4). Please clean the appearance of base metal before welding.
5). Use the wire under the best possible condition. It should be used up as soon as possible when unpacked.
