Welding and Joining Technology

Welding is the most common way of permanently joining metal parts. In this process, heat is applied to metal pieces, melting and fusing them to form a permanent bond. Welders work in a variety of industries, from car racing to manufacturing. The difficulty of the weld is determined by its position-horizontal, vertical, overhead, or 6G, circular, as in large pipes, and by the type of metals to be used. Welders and cutters may work outdoors, often in inclement weather, or indoors, sometimes in a confined are designed to contain sparks and glare. About 50% of welders, solderers, and brazers work 40 hours a week, overtime is common, and about 1 out of every 5 welders work 50 or more hours per week.
