Problems solved by technology

However, higher temperatures can lead to spray transfer or splashing or uncontrolled addition of molten metal from the molten electrode to the pool of molten metal, resulting in poor deposition and inability to control the shape of the deposited layer
Excessive temperatures in the preheating zone or melt pool can also lead to deformation of thin layers during deposition
