Shielded Metal Arc Welding (abbreviated as SMAW). The principle is: an arc is generated between the coated electrode and the base metal, and the welding method using the arc heat to melt the electr...
Important structures such as boilers and pressure vessels require safe penetration of joints, but due to limitations in structure size and shape, double-sided welding is sometimes impossible. A sp...
The preparation work before welding is as important as the welding process, which is directly related to the welding quality and effect of the finished product.
