Weld - a crystallized metal, which is in the process of welding is in the molten state.

Welded joints - a limited area of construction, containing one or more welds.

Types of welds
Depending on the shape of the cross section welds can be

• butt;
• angle;
• slotted

Types of welded joints
Depending on the nature of the workpiece interface the following types of welded joints:

• butt joints;
• corner joints;
• T-joints;
• lap joints;
• Mechanical connections.

Butt joint is welded to the two elements adjacent to each other and the end surfaces located on a surface or in the same plane.

Figure. Butt welds: no bevel the edges with a curved bevel edges, with V-shaped bevel edge, with the X-shaped bevel edge

Angular coupling is welded to the two elements, placed at an angle and welded to the junction with their edges.

T-joints is called a weld, which abuts the end face of one element at an angle and attached to the lateral surface of another element.

Figure. Corner and fillet welds: no bevel edge, with a bevel edge, with two single edge bevels

Lap connection is placed parallel to the weld and partially overlapping elements.

Mechanical connection is a welded joint in which the side surfaces of the elements adjacent to each other.
