Clamp-on weld heads expand orbital system for welding small-diameter pipe, tube

May 29, 2014

The Lincoln Electric Co. offers HELIX® C450 and C663 weld heads for welding various pipe and tube sizes. With these orbital GTAW clamp-on weld heads, operators not only can weld large diameters with no upper limit, they also can weld smaller tubes and pipes with ODs from 1.315 to 6.63 in. The weld heads are designed for use with the company’s APEX® 2100 orbital welding system.

The C450 weld head is designed for pipes and tubes with ODs from 1.315 to 4.5 in., while the C663 weld head is designed for 1.9 to 6.63 in. dia. Their water-cooled motor housing and torch help ensure extended performance and high cycle ratings in heavy-duty, high-heat applications.

The weld heads are intended for use with the company’s new HELIX WF20S and WF20B orbital wire feeders. The feeders use a precision wire feed motor to ensure calibrated and consistent wire feed speed through the length of the weld. The design allows the operator to change wire spools in less than a minute without tools.

The orbital welding system is engineered for diverse applications in demanding environments and restricted spaces. With this system, operators can retrieve specific weld programs for each application to maintain quality control procedures and gather weld information for future statistical reporting.
