Weld Backings

Bug-O Systems weld backings are non metallic, non hygroscopic, neutral, and unlike metal backing bars, do not become part of the finished weld. When properly positioned and attached to the back side of a weld joint, your welds can be free of defects eliminating rework and cleanup associated with poor root welds. One-sided one-pass and one-sided muti-pass welds are possible with Bug-O Systems' weld backings. Our backings support molten weld metal over a wide range of welding heats resulting in uniform back beads of finished quality.
