Conversely, AC alternates direction thousands of times per second, creating a cleaning action that removes surface contaminants but offers less concentrated heat. Situations where the metal has been subjected to high heat and discoloration.
Understanding DC Electron Flow for Consistent Steel Welds
The Role of AC Current in Steel Fabrication While DC dominates thick steel applications, AC current plays a specific and vital role in the TIG process. Choosing the right current for TIG welding steel is fundamental to achieving clean, strong, and aesthetically pleasing welds.
Advantages of DCEN for Thicker Materials Deep, efficient penetration suitable for steel over 1/8 inch thick. Material Thickness and Joint Design The physical properties of the workpiece should heavily influence your choice of current.
