In order for welding to be fully accepted as a tool in engineering, the passing of information from the architect of the design and the end user must be accurate and fully understood. One way of doing this is by using widely accepted welding symbols which enable design drawings to be completed with welding information. The […]

There are three basic welding methods: manual, semiautomatic, and automatic. Manual welding is the oldest method, and though its proportion of the total welding market diminishes yearly, it is still the most common. Here an operator takes an electrode, clamped in a hand-held electrode holder, and manually guides the electrode along the joint as the […]

Altogether, there are approximately 100 types of welding. When you learn to weld, you will learn the differences among them. Differences are due to the molecular nature of the materials, required precision, and environment in which the welding takes place. For example, a sculptor might use a gas flame to weld two pieces of metal […]
