The influence of welding parameters and processes on weld seams
When the welding current increases (other conditions remain unchanged), the penetration depth and residual height of the weld increase, while the melt width remains unchanged (or slightly increases), for the following reasons:

Four common welding defects in boiler pressure vessels
The welding quality directly affects the performance and safety of the boiler structure. Poor welding quality of the boiler may lead to leakage or even explosion accidents, causing significant losses to people's lives and property. Therefore, exploring the causes of welding defects in boilers, mastering their preventive measures, and effectively improving the welding quality of boilers are of great significance for ensuring the safe operation of boilers.
