WELDING
TECHNOLOGIES

"United Industrial Complex" delivers a wide range of cored wire with various diameters, levels of protection and mechanical properties, as well as with the possibility of welding in different spatial positions.

SAVING TIME AND RESOURCE

In the conditions of construction and installation, industrial enterprises and shipbuilding facilities, the use of powder wires that meet the necessary technical requirements and high performance requirements has become one of the leading areas of mechanization of welding where other mechanized methods of repair can not find application.

ADVANTAGES OF WELDED POWDER WIRE OF OPK

• Welding in all spatial positions for one and / or several passes
• Welding in a shielding gas environment CO2 or a mixture of Ar + CO2
• High performance and practicality
• Stable arch
• Easy removal of welding slag
• Low spatter of metal
• Low tendency to cold cracking due to low hydrogen content
• Good weld appearance
• The weld metal has high strength characteristics at t = up to -60С
• Weld metal has excellent resistance to cracking, intergranular corrosion and high mechanical properties
• The ability to weld dissimilar materials, stainless steel with carbon and low-alloy steel
