This welding center mainly consists of column-boom、SAW and electric system.

Column-boom

(1)This column-boom is mainly composed of:boom-elevate unit、boom travel unit、column revolve unit、movable troColumn and boom welding manipulatorlley、cross-slides、column、boom、trolley、worktable and electric system;

(2) Both column and boom are rectangular-section beams, with double-rail, which is welded into shape、stress-relieved and mechanical machined finely, ensuring higher precision;

(3)Boom-elevate unit is installed at column-top, composed of A.C. braking motor、reducer、chain and sprocket. It has counter-balance, making stable boom elevation. To prevent chains from incidental broken, ratchet-type anti-dripping unit on the column is used for safe and reliable operation.

(4) There are 8 sets of control rollers on the saddle along vertical and horizontal movement. Each set has 3 control rollers. These control rollers are contacted with rails of boom and column through 3-sides, of adjustable eccentric structure, with great loading capacity, making good contact between them and rail surface, ensuring smooth and no shivering boom travel;

(5) Boom travel is realized with A.C. inverter motor through worm-gear reducer driving gear-rack. Its speed can be adjusted within 100-2000mm/min through inverter,

(6) Column is fit onto trolley through heavy-duty cross-roll bearing. Column can be revolved within ±180° manual KB-20 seam-tracker

This welding center is equipped with Korean COWELD seam-tracker. Automatic cross-slides of seam-tracker has 100kg loading capacity. The 2 Welding guns are mounted on it, arranged in parallel. Cross-slides is riveted with boom by means of a swivel-shaft, revolving around shaft and then fixed. Swivel of cross-slides can meet inner and outer longitudinal and circumferential welding requirement. It is applicable for double-gun

Control system

Control system mainly consists of control board and remote panel.

(1) Control board mainly controls ON/OFF of motors, realizing motions and applying necessary protection on motors, as well as control、speed-control and protection of boom travel motor.

(2) There are limit switches for boom elevation、travel and column revolve, protecting equipment;

(3) Applicable voltage of main frame: 380V/50HZ/3P(Other voltage can be customized)
