Low-temperature steel submerged arc welding wire
Low-temperature steel submerged arc welding wire is specifically designed for welding equipment operating in cryogenic environments, such as liquefied natural gas (LNG) storage tanks and polar vessels. Its core function is to ensure the toughness and crack resistance of the weld at low temperatures.
Heat-resistant steel submerged arc welding wire
Heat-resistant steel submerged arc welding wire is a welding material specifically designed for welding components operating at high temperatures (such as power plant boilers, pressure vessels, and pipelines). Its core objective is to ensure that the weld exhibits stable mechanical properties, excellent creep resistance, and good oxidation resistance at high temperatures.
Stainless steel submerged arc welding wire
Stainless steel submerged arc welding wire is a submerged arc welding material specifically designed for welding stainless steel. It works in conjunction with a matching flux to obtain welds with specific corrosion resistance and mechanical properties.
High-strength steel submerged arc welding wire (SAW)
High-strength steel submerged arc welding wire is a welding material specifically designed for welding low-alloy high-strength structural steels with yield strength typically above 490 MPa (approximately 70 ksi). Its core objective is to ensure that the weld metal achieves high strength matching the base metal while possessing excellent low-temperature impact toughness and good crack resistance.
Carbon steel submerged arc welding wire
Carbon steel submerged arc welding wire is the filler metal used in submerged arc welding (SAW) processes for welding carbon steel. A key characteristic is that it must be used in conjunction with flux, which plays crucial roles in protection, purification, and alloying during the welding process.
