Seam Welding Machine Welding And Automatic Welding Composition

Seam welding machine welding and automatic welding composition

The thickness of the joint is similar to that of spot welding (except for the joint of the seam and the pad). Roller does not like the spot welding electrode can be made into a special shape, so the actual seam welding machine structure, we must pay attention to the reachability of the roller.

When welding a small radius of curvature of the workpiece, the inner roller radius of the reduction is subject to certain restrictions, will inevitably cause the nilting to the outside of the shift, even the inner plate is not welded, this should avoid the design of the radius of the workpiece is too small. If there is a straight part on a workpiece, but also a small radius of the radius of the part, such as motorcycle fuel tank, in order to prevent the small radius of the radius of the weld is not welded, you can weld to this site, increase the welding current The In addition, the roller diameter or plate bending can cause nugget offset, designed to avoid.

Seam welding machine seam welding is the spot welding spot welding another form, in the seam welding to form a continuous weld of the solder joints overlap each other. Due to the close distribution of adjacent solder joints, although the heat resistance of the adjacent welds is high, the current flow is still very large, to get high quality, tighten the tight weld, it must ensure that the welding parameters as much as possible stable.

The construction of automatic welding equipment for seam welding machine

1, welding power, its output power and welding characteristics should be used with the proposed welding process to match, and with the main controller connected to the interface.

2, the welding head with its moving mechanism, which by the welding head, welding head support frame, hanging towers and other components, located in the precision welding head body, the drive system should be equipped with encoder servo motor;

3, the main controller, also known as the system controller, mainly for the various components of the linkage control, welding program control, the main welding parameters set, adjust and display. If necessary, can be extended fault diagnosis and man-machine dialogue and other control functions.

4, the welding movement or displacement mechanism, such as welding roller frame, head and tail frame turning machine, rotary platform and positioning machine, precision mobile displacement mechanism should be equipped with servo motor drive

5, wire feeder and its control and speed control system, Seam welding machine for the wire speed control accuracy requirements of a higher wire feeder, the control circuit should be added speed feedback;

6, welding parts clamping mechanism;

7, computer software, welding equipment commonly used in computer software: programming software, functional software, process software and expert systems, etc.

8, welding head guide or tracking mechanism, arc pressure automatic controller, torch bobbin and monitoring system

9, auxiliary equipment, such as wire feeding system, Seam welding machine circulating water cooling system, flux recovery conveyor, wire support, cable hose and towline structure design electrical control design of the three major parts.

10, welding robot, also known as mechanical arm, is an important part of automated welding equipment. Its main work includes: welding, cutting, thermal spraying, handling and so on.
