Industry & Occupation
Classification
Summary
Specialist profession that performs welding and repair of cast parts using oxygen-acetylene gas.
Description
Casting welders (gas welding) are specialists who use a torch mixed with oxygen and acetylene gas to weld and repair cast iron parts. The work consists of processes including part cleaning, preheating, welding, annealing, and inspection. They read drawings, set appropriate welding conditions, operate the welding rod, and carefully finish to avoid distortion or gaps. Since the work involves high-temperature environments or hazardous gases, operation of safety equipment and wearing protective gear is essential. Additionally, durability is ensured through quality control and dimensional inspections.
Future Outlook
While manufacturing automation advances, welders with advanced repair skills remain in high demand.
