Heat-Resistant Support for Clean, One-Sided Welds
Knowing how to support the weld puddle from the backside is especially important when welding thin materials. Weld backing tapes provide heat resistance and structural support, helping you achieve clean root profiles while reducing post-weld cleanup.
The fiber-insulated aluminum weld backing tapes available are designed for dependable performance on demanding applications. Featuring a woven glass fiber insulating strip, these tapes help manage heat and support the weld pool for consistent, high-quality results.
Available in 200 amp and 600 amp ratings, these backing tapes allow you to perform one-sided welding on thin-wall stainless steel sheets and vessels—often eliminating the need for back purging.
How weld backing tape improves weld quality
- Supports the weld puddle for a smooth, consistent under-bead
- Helps envelop the weld pool with shielding gas
- Reduces burn-through and distortion on thin materials
- Minimizes post-weld cleanup and finishing
Compatible with multiple welding processes and materials
Weld backing tapes are suitable for use with SMAW (Stick), GTAW (TIG), and GMAW (MIG) welding processes. They perform reliably on carbon steel, stainless steel, and aluminum alloys, making them a versatile solution for a wide range of fabrication needs.
Achieve cleaner roots, reduce cleanup, and simplify thin-material welding with weld backing tapes trusted by the pros.
