A Beginner's Guide To Welding

What is Welding?

Welding is the process of joining metals by heating their surfaces and uniting them with pressure. When the heated metals cool together, they form a strong joint. Often times, a filler material is used between the two objects.

Metal joining has been a valuable skill for thousands of years. In the Middle East during the Bronze Age, welding was used in the building of weapons and structures. During the Middle Ages, forge welding became popular as blacksmiths joined metals using a rigorous process of heating and hammering. When the electric arc was discovered in the 1800s, it ushered in a newer, safer way of welding. As the world approached the end of the 20th century, it became the industry standard.

Types of Welding

Welding requires an energy source to heat the instrument. Gas flame, ultrasound, laser and electron beam can all be used to melt the work piece. Today, the most common type of welding is arc welding. This method uses an electric arc that travels from the tip of the welding rod to the grounded metal. Welding can be performed by humans or robots, and can be done on land, in the air, underwater and even in outer space. Welding can reinforce weak joints, cut and shape raw metals, fix stress cracks and build art sculptures.

Welding Safety

A tool's safety depends on the vigilance of its operator. Welding can be a safe way to accomplish many tasks. But when precaution is shirked in favor of efficiency, welding can be incredibly dangerous.

Burns and fires are the greatest risks associated with welding. Welders should always wear a protective long sleeve jacket and heavy-duty leather gloves. To keep the eyes safe from the bright light and occasional flying sparks, goggles and tinted welding helmets should be worn. Equipment must be properly grounded, floors should be dry and the work area needs to be adequately ventilated to prevent fume inhalation.
