Vertical welding with stick electrodes gives many welders trouble. The molten metal wants to drip downward, the puddle sags, and the bead ends up uneven. But vertical welding is not as hard as it...

Welding current, voltage and welding speed are the main energy parameters that determine weld size.
1. Welding current
When the welding current increases (other conditions remain unchanged), the pe...
Welding defects can be divided into two main categories based on their location in the weld: internal defects and external defects.
External defects are located on the outer surface of the weld an...
Jeremy “Jay” Lockett of Kansas City, Missouri will be the first person to tell you that everything he did in his career related to welding was abnormal.
This 29-year-old young man did n...
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...
