Welding Applications & Procedures

In the past, full penetration welding involved costly backgouging, grinding, and rewelding. With Cerbaco Ltd. non metallic weld backings you can achieve X-ray quality, full penetration welds from one side and in a single pass. The result is a finished high quality weld and a savings of labor, materials and time. Cerbaco weld backings are manufactured in many different configurations and in formulas for the diverse conditions encountered when welding anything from light gauge sheet metal to heavy metal fabrication. Cerbaco weld backings can  be used to compensate for poor fit-ups, and is a valuable tool when welding conditions are not ideal or where the back side of a weld joint is inaccessable.

Cerbaco 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 multi-pass welds are possible with Cerbaco weld backings. Our backings suport molten weld metal over a wide range of welding heats resulting in uniform back beads of finished quality.

Step 1. Start with an open root:

Step 1 - Open Root

Backing will vary depending upon root opening, joint design and welding process.

Step 2. Apply backing:

Step 2 - Apply Backing

In most applications, backing is applied using our adhesive foil on which the backing is assembled. The area to which the backing will be attached should be free of loose rust, dirt and oil.

Step 3. Weld:

Step 3 - Weld

Establish your arc and weld a root pass.

Step 4. Remove backing to reveal finished backbead:
