1. Basics of Welding

Welding involves heating the materials to their melting point and then applying pressure or filler material to form a joint. Key concepts include:

?? Heat Source: Various heat sources, such as arcs, lasers, and flames, are used to melt the base materials and create a molten pool.

??? Filler Material: In some welding processes, additional material called filler is added to the joint to enhance strength and stability.

?? Joint Design: Proper joint design is essential for ensuring weld quality and integrity, with factors such as groove geometry and fit-up influencing the welding process.

2. Common Welding Techniques

There are several welding techniques, each suited to specific materials and applications. Some common techniques include:

?? Arc Welding: Uses an electric arc to melt the base materials and form the weld, with variations such as shielded metal arc welding (SMAW) and gas metal arc welding (GMAW).

?? Oxy-fuel Welding: Utilizes a mixture of oxygen and fuel gas to produce a flame for melting the base materials, commonly used in metal fabrication and repair work.

??? TIG Welding: Also known as gas tungsten arc welding (GTAW), TIG welding uses a non-consumable tungsten electrode to create the weld, providing precise control over the welding process.
