What type of welding process is referred to as the manual process in LA City certification?

The manual welding process referred to in LA City certification aligns with gas welding. This process involves utilizing a flame generated by burning a fuel gas, typically acetylene, mixed with oxygen, to melt and fuse metals together. It requires the welder's skill to control the flame and the filler material while manually manipulating the welding torch.

In the context of certification and skill requirements, gas welding emphasizes hand-eye coordination and the ability to maintain precise control over the welding parameters. This is distinct from other processes, such as stick welding, which while also manual, is more commonly recognized as a specific type of arc welding that uses a consumable electrode.

Gas welding's designation as the manual process in certification highlights the traditional roots of welding techniques, showcasing the craftsmanship involved in this method, which is vital for certain applications. This understanding helps differentiate between various welding processes and their classifications within welding certification programs.
