Final answer:
To prevent carbonization problems during gouging, ensure proper current settings, maintain correct torch angle and speed, and clean the gouging area regularly.
Step-by-step explanation:
To avoid carbonization problems while gouging, it is essential to use the correct current setting and maintain proper torch angle and speed.
A correct current setting ensures the arc is stable and the metal is removed efficiently without overheating, which can cause carbonization.
Additionally, the torch angle should be consistent and appropriate for the type of gouging being done. A correct angle aids in the ejection of molten metal and prevents it from re-depositing on the surface. Lastly, maintaining a steady and appropriate speed is crucial; if gouging is done too slowly, it can result in excessive heat input and carbonization. Regular cleaning of the gouging area can also help prevent carbon accumulation.
