A groove weld is a type of weld used to join two pieces of metal together by creating a groove or channel between them. This groove is filled with molten metal during the welding process, allowing for a strong bond once it cools and solidifies. Groove welds are commonly used in structural applications where strength is critical. There are various types of groove welds, including butt welds and corner welds, each designed for specific joint configurations. The choice of groove weld type depends on factors like the thickness of the materials and the desired strength of the joint. Proper preparation and technique are essential for achieving a quality groove weld.
