Welding Essay Introduction

Welding is the process of joining two metals together by heating them up to molten hot temperatures, and then manipulating the molten weld puddle to create a weld bead. A lot is involved with welding like metal cleaning, fit up, cutting, making measurements, making sure you’re using the correct welding processes, and much more.

Welding in the early days

Before there were any arc welding processes or oxy acetylene gases to heat up the metal, there were blacksmiths. Blacksmiths had to heat up the metal using a heating forge, and rather than bring the metal to a liquid temperature and weld it, they had to hammer the steel together. This process fused the metal together, and it’s called forge welding. Up until the mid-1800’s most welding was done this way. Even though this welding process is long and arduous, it’s still the same exact concept as gas welding or arc welding.

The gases are able to be mixed and used for welding through the use of regulators, hoses, the torch mixer, and welding tips. After turning on the gases and lighting them, they must be adjusted for the correct flame to weld properly.

• You must direct the flame at the weld joint and use a filler rod to help make the weld bead.

• You have to use a bigger tip for thicker metal, and a smaller tip for thinner metal.

• You also have to adjust the regulator pressures to deliver the right amount of gases at the welding tips.

• If you have the pressures set wrong you may over heat the metal, or not heat it up enough to start the weld.

Arc welding has essentially taken the place of oxy acetylene welding since it’s come into use. Arc welding is much faster, much more efficient, and produces better welds.
