SUBMERGED ARC WELDING WIRE

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.

Product Introduction

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.

Core Advantages

• 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%

Application Areas

• 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
