Welding clamps are tools used to hold metal pieces together securely during the welding process. They come in various shapes and sizes, designed to accommodate different types of joints and materials. By keeping the workpieces stable, welding clamps help ensure accurate and clean welds. These clamps are typically made from durable materials like steel or aluminum, providing strength and resistance to heat. Some common types include C-clamps, toggle clamps, and pipe clamps. Proper use of welding clamps can significantly improve the quality of the weld and enhance safety by preventing movement during the welding operation.
