welding electrode storage and selection
In several manufacturing projects across South America, we often see companies focus heavily on welding machines and operators, but underestimate how welding electrode selection and storage affect weld quality……

E7015 is a high-performance, low-hydrogen basic electrode known for its excellent crack resistance and superior weld mechanical properties. It is primarily used for welding carbon steel and low-alloy steel structures requiring extremely high quality. The key to its successful use lies in strict pre-welding drying and heat preservation measures, as well as the requirement for DC reverse power supply. If you are welding load-bearing structures, pressure vessels, or equipment working in harsh environments, E7015 is usually one of the preferred electrodes.
