The boom crane truck is also known as truck-mounted crane. It is a special vehicle that uses the hydraulic lifting and telescopic system to realize the lifting, turning and lifting of cargo. It has the advantages of good mobility, rapid transfer, flexible and multi-purpose. . Whether its welding is reliable or not is very important, and its safety and bearing capacity are closely related.
The welding we are talking about is mainly the welding of the boom. The most important one is the shape of the boom section, the material of the boom, the welding method of the boom section and so on. In general, regardless of whether the cross section of the boom is hexagonal, octagonal or U-shaped, it does not cause the boom to break within the allowable range of the performance map, but in actual operation, many people are hoisting the cargo. When the belt is loaded and contracted, it is very good to test the quality of the welding of the boom.
The size of the weld is an indicator of the shape of the weld and is one of the important factors affecting the quality of the weld.
The weld is too wide and the weld size is too large: this situation will cause the welded joint to be heated to a serious extent, the weld bead is coarse, the plasticity and toughness are reduced, and the welding heat affected zone is large, and the joint stress and deformation are easy to occur. It will waste materials and increase production costs.
The weld is too narrow and the weld angle is too small: this situation will cause poor fusion of the base metal and the weld, which will cause stress concentration, which is a defect such as undercut and crack in the weld, which will affect the strength of the joint.
It can be seen from the above that the correct determination of the weld size is the key to ensure the quality of the weld.
Nowadays, many manufacturers have begun to adopt automatic welding technology. The automatic welding technology is easy to operate and easy to use. It also effectively improves the welding quality. The welding time in the short time is also greatly shortened. The welded crane jib is welded. Beautiful appearance and stable quality. Automatic welding technology is not only suitable for truck-mounted cranes, but also for vehicles such as mixer truck mixing tanks, suction truck suction tanks, etc.
