Welding is a process that joins two pieces of metal by heating them together until they melt and form a joint. Welding is used in a variety of applications, including construction, manufacturing, and aircraft maintenance.
The most common type of welding is arc welding, which uses an electric arc to heat the metal to the melting point. However, there are other types of welding, including mig welding and oxy-fuel welding.
Welding Techniques
Welders use a variety of welding techniques to join different types of metals. The most common welding techniques are arc welding and mig welding. Arc welding uses an electric arc to heat the metal to the melting point. Mig welding uses a metal rod that is inserted into the weld area and moved around until the weld is complete. Oxy-fuel welding uses a type of gas that is used to heat the metal to the melting point.
Safety in Welding
Welders must take precautions to ensure safety when welding. For example, welders should wear protective gear, including a helmet, gloves, and a face shield. They should also use approved welding equipment and materials.

Welding goggles can be used as a degree of eye protection, while some forms of welding and cutting are being done. The sunglasses are designed to protect the eyes not only from the heat and from the radiation that is generated by welding, such as the intense ultraviolet light that is produced by an electric arc, but also from sparks and other debris.
Some welders wear a shaded safety glass underneath their helmets. In close quarters, you should wear welding-rated glasses if you are trying to weld a large part, especially if you are wearing a helmet. Even during the light welding process, you must wear at least 5 shades of lenses to protect your eyes.
So you should always wear safety glasses with adequate shields to prevent arc flash. When someone experiences an arc flash, it is proof that he / she did not wear safety glasses. If you have safety glasses, you can look directly at an arc welding through those glasses and not get an arc burn.
In the UV spectrum, green lenses are worn to block infrared (IR) light and to protect the eyes from the heat. They are very effective in protecting you from the effects of flashing or exposure.
You will be able to see that the light of an arc welding will travel horizontally, vertically, and diagonally. A lens with polarized lenses would not be able to protect you against all these kinds of light, and it would allow enough light through to damage your eyes. If a welding arc was arc, it would be too bright for even the darkest polarized lens to handle.
Welding Tips
Here are some tips to help you get started welding:
- Always wear protective gear, including a helmet, gloves, and a face shield.
- Use approved welding equipment and materials.
- Start with a low arc setting and work your way up as needed.
- Use the correct filler metal for the job at hand.
- Make sure the work area is clean and free of debris.
