Welding is a process that joins two pieces of metal by heat and pressure. It is a versatile and common welding technique that can be used in many different applications.
Welding Basics
The most common welding technique is arc welding, which uses an electric arc to create a weld. Welding can also be done using gas or oxyacetylene welding, which use different types of flames to create the weld
Welding Materials
Welding is most commonly used to join metals, but it can also be used to join other materials such as plastics and composites. The most common metals used for welding are steel and aluminum, but other metals can also be welded including copper, titanium, and brass.

Welding Processes
There are three main welding processes: MIG (metal-in-gase), TIG (tungsten-in-gas), and FCAW (flare-cored arc Welding). Each process has its own advantages and disadvantages, so it’s important to choose the right one for the job.
Welding Techniques
There are a number of different welding techniques, but the most common are MIG and TIG. MIG welding uses an electric arc to weld metal, while TIG welding uses a tungsten electrode to create the weld. FCAW is a newer technique that uses a shorter, more intense electric arc to create the weld.
Welding Tips
- Here are some tips for successful welding:
- Test the weld before you start to make sure it’s strong enough.
- Use a consistent welding process and settings to ensure a quality weld.
- Clean the area before you start welding to avoid contamination and oxidation.
- Weld with caution around sharp edges and other potential hazards.
Welding Safety
Welding is a dangerous process and should only be done by experienced professionals. Always wear protective gear and use safe practices when welding. Follow the guidelines provided by your welding supplier to ensure safe welding.
Can you close your eyes while welding?
No, you should not close your eyes while welding. It is also important to keep an open mind while welding to avoid distractions. Therefore, not only will you not be able to see where you are working, but the UV rays from the arc will also enter your eyelids and burn your eyeballs. It is not recommended that you do this in order to protect your eyes. It is better to use a welding helmet.
Can you go blind from looking at welding?
When welders do not properly protect their eyes from the arc, they frequently experience welder’s flash or photokeratitis. This is a condition caused by exposure to intense ultraviolet radiation, which causes people to become temporarily blind and very uncomfortable. Sometimes, very severe eye injuries can cause permanent blindness.
How long does it take to get eye damage from welding?
Corneal flash burns are caused by a very strong light that is directed at the cornea. That is, corneal flash burns are often caused by skiing without glasses, welding arcs, sun lamps, etc. After the burn, if you experience pain and swelling in your eyes and blurred vision, it is advisable to be cautious. You should be cautious about a burn about 6 to 12 hours after the burn.
