Welding process for ASTM A588 Gr.A weathering steel
Different from ordinary steel plates, ASTM A588 Gr.A weathering steel has good corrosion resistance. Under severe weather such as acid rain, many buildings began to show different degrees of corrosion, which not only affected the buildings, but also affected the people in the buildings. At the same time it also brings some security risks.
Speaking of Corten Steel , specialised Corten Steel is used for proper functioning . Cortensteeltube.com Is one leading Manufacturer, Supplier & Stockist Of Corten Steel ASTM A588 Grade A Plate & Sheet.
The weathering resistance of ASTM A588 grade A weathering steel in construction also slows down the corrosion phenomenon of buildings, and achieves a good application effect.
Welding weathering steel is relatively simple. It welds very similar to some of the common low carbon steels such as ASTM A588 weathering steel is a structural steel covered under the AWS D1.1. Structural Welding Code. It is a group II steel which means prequalified welding procedures may be used.
- Process the grooves in the welds of ASTM A588 Gr.A weathering steel and stainless steel plates respectively
- After polishing and removing the dirt around the groove, pair the groove of ASTM A588 Gr.A weathering steel with the groove of the stainless steel plate to form a welding area;
- Non-pulsating solder is used in the weld zone formed between ASTM A588 Gr.A weathering steel and the stainless steel plate to form a primer layer at the lower part of the weld zone;
- Non-pulsating solder is used to cover the upper surface of the soldering layer in the soldering zone to form a covering layer in the ASTM A588 Gr.A weathering steel soldering area. By welding weather-resistant plates and stainless steel plates under low current and voltage, reducing the heat of ASTM A588 Gr.A weathering steel and stainless steel during the welding process, effectively reducing the melting rate of the two plates, and manufacturing ASTM A588 Gr.A weathering steel and stainless steel. It can be more completely fused to improve the weldability of welding.
