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...
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...
One of the most frustrating moments for a beginner welder is striking an arc only to have the electrode stick to the workpiece. It sticks, glows red, and you scramble to twist it free. Don’t worry...
In steel structure fabrication, flat position welding is the most basic and commonly used position, and it is also the easiest to achieve good weld quality. Although flat welding is relatively les...
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...
