Advantages of automatic spot welding machine

1. Practicability

Automatic spot welding machine is a kind of high-strength and high-efficiency building material for concrete reinforcement. It is a kind of steel mesh with resistance spot welding at all crossing points. It can separate the longitudinal and transverse cold drawn and cold-rolled steel bars required by the design with a certain distance through the automatic production line in the factory. It is used in floor, floor, shear wall, road pavement, bridge deck pavement, box culvert, wharf floor, prefabricated components and other fields. To save the amount of reinforcement, the welded wire mesh is made of low-carbon hot-rolled wire rod by cold drawing or cold rolling. The tensile strength of the wire rod is improved to more than 550MPa, so the amount of reinforcement can be reduced by more than 30%.

To improve the quality of the project, the welded steel mesh is manufactured by the automatic production line according to the international common design and technology. The production process can be effectively controlled by strict quality control, grid scale, steel bar standard and other quality requirements. There will be no scene of missing, wrong or shoddy binding of site personnel, so as to improve the quality of the project.

2. Increase production power

The use of steel mesh can save the time of binding on site (save more than 70% of working hours), which is conducive to the arrangement of subsequent concrete construction and shorten the construction period. As a new type of building material, cold rolled ribbed steel bar and welded steel mesh have been listed as the key points of the ninth five year plan by the Ministry of construction of the people's Republic of China. The application of building materials and 10 new technologies in the construction industry have been further promoted. It will be widely used in the construction industry, improve the industrialization level of steel engineering, and achieve good economic and social benefits.

3. Improve crack resistance

The manufacture of automatic spot welding machine is carefully checked, then arranged according to the design standard, and then applied with electric current to make the intersection of longitudinal and transverse reinforcement in the complex. The spacing of the whole net is uniform, the stress transmission is uniform, and the load can be evenly distributed on all concrete structures, which can prevent the occurrence of cracks. According to the practical test results, the cracks can be reduced by more than 75% when the steel mesh is laid on the road.

Disadvantages of automatic spot welding machine

1. Due to the lack of reliable nondestructive testing methods, the welding quality can only be checked by the destructive tests of process samples and weldments, as well as by various monitoring techniques.

2. The lap joint of spot and seam welding not only increases the weight of the component, but also forms an angle around the nugget between the two plates, resulting in low tensile strength and fatigue strength of the joint.

3. The high power, mechanization and automation of the equipment increase the cost of the equipment. Maintenance is difficult, and the commonly used high-power single-phase AC welding machine is not conducive to the normal operation of the power grid, so it needs to be distributed separately.
