Open vs. Closed Weld Heads in Orbital Welding

Open vs. Closed Weld Heads in Orbital Welding

October 12, 2021

Today’s selection of welding processes is certainly not one and the same. Over time, the increase of documentation requirements, quality awareness, strict standards, and shortage of skilled and experienced workers have called for a more automated, precise method. Orbital welding is an effective assembly solution for present-day production. You will find the demand for orbital welding systems on the rise in a wide array of modern industries.

Operators of this gas-shielded welding process can choose to utilize either an open weld head or a closed weld head to weld tubes or pipes in place. How is this decision made? Let’s examine closer the topic of open vs. closed weld heads in orbital welding. Here’s what you need to know about the function of these essential components.

Traditional Orbital Weld Heads: Closed

Orbital weld heads are relatively complex machines with numerous functions. Essentially, a weld head controls the movement of the electrode, maintains the heat temperature, and applies pressure to the weld joint from a certain distance. Choosing between an open or closed weld head depends on several factors, including workspace, welding material, and the type and size of the workpiece to be welded.

Closed weld heads are comparatively compact in design—ideal for on-site welding pieces with smaller sections. Their closed design effectively shields and protects the welding site. A closed weld head offers simple operation, creating clean seams without any misalignment or gaps.

Alternative Orbital Weld Heads: Open

When comparing open vs. closed weld heads in orbital welding, the main distinction lies within their applications. Open orbital welding guns come in handy for specific on-site circumstances, such as welding at different angles and thicker multilayers. Many operators use open weld heads for larger wall thicknesses or increased pipe breadth due to the open design of the arc.

Closed welding heads are typically available for smaller pipe diameters. Conversely, open welding heads hold an advantage. These alternative options can cover pipe diameters of up to 270 mm.
