Weathering steel plate is a kind of weather-resistant steel that is mainly used to manufacture various structural parts, containers and equipment to cope with harsh climate and environmental conditions. When welding weather-resistant steel plates, appropriate welding rods should be selected to ensure welding quality and durability.
Commonly used electrodes for welding weather-resistant steel plates include the following:
◆ Silicon-molybdenum series welding rods: Silicon-molybdenum series welding rods are suitable for welding weathering steel and other high-strength steels. It has high welding strength and corrosion resistance, and is suitable for use in harsh environments.
◆ Nickel steel series electrodes: Nickel steel series electrodes can be welded at low temperatures and are suitable for cold welding of weather-resistant steel plates. It has high strength and corrosion resistance and is suitable for use in harsh environments such as strong acid, strong alkali and high temperature.
◆ Chromium-molybdenum series electrodes: Chromium-molybdenum series electrodes have high tensile strength and heat resistance, and are suitable for welding high-strength, high-temperature and weather-resistant steels. It has good corrosion resistance and is suitable for use in acidic and alkaline environments.
