Frequently Asked Questions
1. Can I weld different types of metals with the same welding machine?

It depends on the type of welding machine. Some machines, like MIG and TIG welders, are versatile and can weld a variety of metals, including steel, stainless steel, and aluminium. However, it's important to ensure that the machine and welding process are suitable for the specific metal you intend to weld.

2. How do I determine the correct welding parameters?

The correct welding parameters, such as amperage, voltage, wire feed speed, or tungsten type, depend on factors like the type and thickness of the metal, the welding process, and the desired weld quality. Welding procedure specifications (WPS) or welding guidelines provided by the manufacturer can help determine the appropriate parameters.

3. Can I weld without using a welding machine?

Welding typically requires a welding machine to generate the necessary heat and electrical power. However, certain specialised techniques, such as forge welding or oxy-fuel welding, do not require a welding machine but have limitations and are less common in modern welding applications.
