The application and development of welding materials influence the advancement of welding technology, the improvement of steel quality and varieties, and the enhancement of quality in various equipment manufacturing industries, infrastructure, and key projects, placing higher technical requirements on welding materials. These requirements are evident in sectors such as heavy machinery, petrochemicals, pipeline containers, nuclear and hydropower, road and bridge engineering, vehicles, shipbuilding, aerospace, and large-scale construction projects.

In China, the consumption of steel and welding materials continues to grow. Against the backdrop of industrialization and urbanization, there is a pressing need to upgrade welding steel grades and welding materials, driving the rapid development of welding technology. The development strategy for welding material products is gradually shifting: highly automated, efficient, and intelligent products are increasingly replacing manual ones. Manual electric welding electrodes are evolving toward high-strength, high-toughness, low-hydrogen, and environmentally friendly characteristics to meet the diverse welding technical requirements of different steel grades, welding structures, and service conditions. Developing new energy-saving, emission-reducing, efficient, and high-quality welding materials has become imperative.

Welding is a manufacturing technology that permanently joins materials to form functional structures. It is applied to products ranging from hundreds of thousands of tons of giant ships to microelectronic components weighing less than 1 gram, with varying degrees of usage across manufacturing processes. Welding has permeated all sectors of manufacturing, directly impacting product quality, reliability, service life, as well as production costs, efficiency, and market responsiveness.
Welding technology encompasses welding materials, equipment, and processes, with welding materials serving as the foundation for technological development in this field.
