Welded joints come in many types, and can be classified according to their connection method into angle joints, butt joints, lap joints, etc.
1. Angle Joints
Angle joints are formed by welding two or more components together at a certain angle. Common types include T-joints and cross joints. Advantages include compact structure and easy welding; disadvantages include uneven stress distribution and unsuitability for applications with heavy loads.
2. Butt Joints
Butt joints are formed by aligning the end faces of two components and then welding them together. Common types include butt flat joints and butt angled joints. Advantages include simple structure and strong connection; disadvantages include high welding difficulty and high material requirements.
3. Lap Joints
Lap joints are formed by laying two components flat together like a jigsaw puzzle, with one side bent. Common types include lap flat joints and lap angled joints. Advantages include a strong connection and suitability for applications with heavy loads; disadvantages include complex structure and high material requirements.
