Detailed About MCQs
The gases used in different types of welding would include Oxygen and Acetylene. To use Oxygen in welding, it’s normally mixed with other shielding gases to change the fluidity of the molten metal and it can speed things up too. If you mix it with acetylene, you can create a flame that will be enough to weld steel. Acetylene is very flammable and it is highly combustible in the air. Acetylene produces a very hot flame that is capable of cutting or welding the majority of metals.
