Steel Structure Welding Automation
Steel structure fabrication involves high volumes of repetitive fillet welds on H-beams, box beams, columns and plate assemblies. Manual welding is consistent but slow, and quality varies with operator fatigue. CBOXTEC robotic welding systems automate these welds with repeatable accuracy, faster travel speeds and lower rework.
Rail-Mounted vs Gantry Systems
For long beams and large plates, rail-mounted robots travel along the workpiece on linear rails. For very large panels—such as ship hull sections or bridge deck units—a gantry robot carries the robot overhead, leaving the factory floor clear for cranes and loading.
Both systems can be equipped with seam tracking, 3D vision and teachless programming to handle part-to-part variation without manual re-teaching.
Key Components of a Structural Steel Welding Cell
A complete cell typically includes:
- Industrial 6-axis welding robot with hollow-arm cable routing
- Welding power source (MIG/MAG, SAW or TIG)
- Seam tracking or 3D vision sensor
- Part positioner or conveyor feeding system
- Custom fixture or clamping system
- Fume extraction and safety guarding
- Offline/teachless programming software

案例研究
江苏省桥梁制造商
一家桥梁钢制造商需要提高箱梁腹板和翼缘焊缝的产量，同时减少返工。CBOXTEC 在 12 米地轨上安装了两台配备 3D 焊缝跟踪的地轨焊接机器人。
我们将翼缘焊接时间缩短了一半以上，一次合格率从 87% 提高到 98%。
泰国钢结构建筑承包商
一家泰国钢结构建筑承包商为满足不断增长的需求，将 H 型钢角焊缝焊接自动化。CBOXTEC 交付了一套完整的 H 型钢焊接机器人工作站，包括自动进料和焊剂回收。
一个机器人工位取代了三个人工工位，让我们最优秀的焊工可以专注于复杂组件。
常见问题
可以。CBOXTEC 钢结构焊接系统经过配置，可生产符合 AWS D1.1、EN 1090 和 ISO 3834 质量要求的焊缝。可提供工艺评定记录（PQR/WPS）。
大多数制造商的回报周期为 12–24 个月。一台机器人通常可取代 3–4 名焊工，产能提升 40–65%。
