welding techniques

Welding techniques involve joining materials, usually metals, by melting them together. Different methods, like arc welding, use an electric current to create heat, melting the base materials and sometimes adding filler metal to strengthen the bond. Gas welding uses a flame from burning gas to melt the materials. Other types, such as TIG and MIG welding, offer more control and precision. Proper technique ensures a strong, durable connection, and the choice depends on the materials and the intended use. Skilled welders carefully control heat, speed, and electrode placement to produce quality joints.
