HF welding impeder system
Discuss the bar within the installed impeder and welding-section arrangement.
HF WELDING & IMPEDER SPARES
Replacing magnetic bars in an XFX tube mill or another existing HF welding line? Send the installed part's photos and dimensions, plus your impeder, welder and tube-production details. XFX can review the requirement before supply is confirmed.
A welder power rating, mill model or tube diameter alone cannot identify a replacement bar. The actual HF welding arrangement must be checked.

01 / PRODUCT ROLE
XFX describes ferrite magnetic bars for impeder systems in the HF welding section of ERW tube mills. They are a related welding component and a possible replacement spare, with material and size selected for the actual tube and impeder setup.
“Magnetic Bars” is the product name on this page. “Ferrite” describes the material named by the XFX listing; an impeder is the assembly or arrangement in which the bars may be used. Those terms are related but do not mean that every impeder uses one fixed bar.
02 / HF WELDING RELATIONSHIP
The XFX sources link the HF welder, induction coil and impeder/ferrite arrangement. This is a discussion map, not a fixed electrical design or bundled supply list.
The primary XFX detail associates ferrite bars with the impeder system and says selection depends on tube size, wall thickness, welding speed, impeder structure, cooling condition and HF welder setup. It does not say every induction coil requires this exact bar.
03 / XFX PRODUCT INFORMATION
XFX identifies these as ferrite magnetic bars used in relevant HF welding impeder systems. The product detail does not list a universal size, specific ferrite grade or rated magnetic properties.
Discuss the bar within the installed impeder and welding-section arrangement.
Ferrite is named by XFX. Confirm the actual material grade and specification for a proposed replacement.
Review tube products, welding conditions, impeder structure and the part itself before confirming the proposed replacement.
The gallery photo shows multiple bar shapes. It is a product-family image, not a dimensional drawing or assurance that any pictured shape fits your system.
04 / REPLACEMENT COMPATIBILITY
Neither HF welder power nor tube size alone establishes the right bar. Send the old part's shape and measurements with your impeder and production information.
Photos, markings if any, cross-section or diameter, length, an existing drawing or sample help identify what is installed.
Describe the assembly, mounting position and cooling method if known. Final interface requirements are checked for the project.
Pair each tube size with its wall thickness. Include material, welding speed and welder brand/model/power if available.
A cracked, worn or missing bar can prompt an enquiry, but a photograph does not establish the cause of a welding problem. The coil, impeder arrangement, setup, tube specification and machine condition may also need review.
05 / REPLACEMENT CHECKLIST
Start with what is available. XFX can identify any further measurements needed after reviewing the existing setup.
Send photos or drawings by WhatsApp or email. The page's text form does not upload files.
06 / THREE BUYER ROUTES
Send the original mill or welder model if known, old bar photos and measurements, impeder arrangement, each tube size with matching thickness, and the required quantity. A machine model alone is not sufficient.
Discuss an XFX replacement ↗Share the current bar, impeder and coil information, welder brand/model/power if known, tube list, drawing or sample availability, installation and cooling details. XFX can discuss the request; compatibility is not assumed.
Send existing-line details ↗Review magnetic bars as a possible item in the HF welding and spare-parts plan. State the proposed line, tube list and desired quantity. Final material, number of bars and supply scope belong in the project quotation.
Plan project spares ↗08 / FACTORY & SUPPORT
XFX has its own factory in China. For tube mill projects, XFX can provide on-site installation and commissioning, operator training, remote technical support, operation and maintenance information, and spare-parts support.
The service and item scope is confirmed in the proposal. A standalone magnetic-bar order does not automatically include an on-site visit or a full-line service package.

09 / BUYER QUESTIONS
XFX places ferrite magnetic bars in impeder systems in the ERW tube mill HF welding section. The actual arrangement must be checked.
No. The bar's size and structure must match the tube specification, impeder design, welding conditions and installed setup.
No. Send old-part photos and measurements, impeder details and the tube sizes with matching wall thicknesses as well.
They can be related in the HF welding arrangement. Review both where relevant, but one fixed combination or bundled supply is not assumed.
Yes, as an enquiry. The actual part and installed arrangement must be reviewed before fit or supply can be confirmed.
All available evidence helps. Send the overall shape, length and cross-section or diameter if measured, plus photos or a drawing; say if a sample is available.
They can be discussed as part of the HF welding spare-parts plan. Final quantity and scope must be set out in the project quotation.
10 / DISCUSS MAGNETIC BARS
Tell XFX whether this is an XFX replacement, another existing line or a new-project spare. Include the impeder arrangement, each tube size with matching wall thickness, welder details and required quantity where known. Partial details are enough to start.
