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 tro
lley、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)
