Frequently Asked Questions

What is a welding rotator?

A welding rotator is an automatic tool that makes it easier to weld pipes, tanks, piles, and other rounded objects. It rotates the workpiece so both hands are free for welding, improving efficiency and weld quality.

What is the difference between a welding rotator and a welding positioner?

A welding rotator rotates cylindrical workpieces around their axis. A welding positioner can both rotate and tilt the workpiece to place the weld in the optimal position for welding, often used for complex or asymmetrical parts.

Can your equipment be customized?

Yes, all our products can be customized according to customer requirements including load capacity, dimensions, speed, and control systems.

Do you offer installation and training?

Yes, we offer on-site installation, debugging, and operator training by our engineering team for an additional service fee.

What is your warranty policy?

All Weld-Fab products come with a 13-month warranty. During this period, any defective spare parts will be replaced immediately. We also provide lifetime technical support.
