submerged arc welding

Submerged arc welding wire has excellent welding and mechanical properties,such,as stable arc,strong removability of slag,good welding seam,high depositing efficiency etc.It is mainly used for press ure vessel,heavy-duty machinery,pipes,transportation,machinery,ship,etc.

EM12K submerged arc welding wire is a high-efficiency welding material designed for high-strength steel structure welding. It is made of Baosteel BGH45A low-carbon steel wire rod. When used with F48A2 flux, it can achieve a stable arc, smooth slag removal, and beautiful weld formation. It is especially suitable for key structure welding in a low-temperature environment of -20℃. The product has passed AWS A5.17 standard certification and is widely used in heavy industrial fields such as oil and gas pipelines, LNG storage tanks, and bridge engineering.

• Ultra-low carbon characteristics: carbon content is strictly controlled below 0.07%, effectively preventing intergranular corrosion of welded joints and improving weld toughness
• Excellent low-temperature performance: -20℃ impact energy reaches 56J, meeting the structural load-bearing requirements under extreme working conditions, 40% better than the industry average
• Precision manufacturing process: from vacuum casting to online annealing, 18 processes are monitored in real time to ensure the stable quality of each roll of welding wire
• Efficient welding experience: the deposition efficiency is 15% higher than similar products, reducing welding time and production costs
• All-position adaptability: suitable for flat welding, horizontal welding, vertical welding and other welding positions to meet the welding needs of complex structures
• Strict quality control: using German Spectro Max spectrometer to ensure the accuracy of chemical composition up to ±0.02%

• Oil and gas pipelines: X80-grade gas pipeline annular seam welding, deep-sea oil and gas pipeline welding
• LNG storage tanks: -162℃ cryogenic storage tank wall welding, liquefied natural gas processing equipment welding
• Bridge engineering: Q345qD bridge steel plate box beam welding, large-span steel structure bridge welding
• Marine engineering: FPSO platform structure welding, submarine pipeline welding, port machinery welding
• Pressure vessels: chemical reactor welding, large oil storage tank welding, nuclear power equipment welding
