Meta-Lax® Weld Conditioning & Vibration Welding | Bonal Technologies  - conditionWhat is Weld Distortion?

During the welding process, the weld metal and adjacent base metal expand and contract during the heating and cooling cycle. For typical weld jobs, where welding occurs on one side of a part, there is a higher degree of distortion than welds that are alternated from one side to the other. There are, however, several factors that affect metal shrinkage during this heating and cooling cycle, such as changing the physical and mechanical properties of the metal when the heat is applied. As you can imagine, as the temperature of the weld area increases, the yield strength, elasticity, and thermal conductivity of the steel plate decreases, but thermal expansion and specific heat increases. These drastic changes naturally affect the heat flow and uniformity of heat distribution across the metal base – or weld distortion. Meta-Lax Weld Conditioning will relieve the thermal stresses as they are being introduced during weld solidification.

Meta-Lax® Weld Conditioning Prevents 50%-90% of the Normal Weld Distortion and Cracking

Bonal developed and patented the concept of using vibrations during welding.  We call this Meta-Lax “weld conditioning” or “pulse puddle arc welding.”  The main benefits of Meta-Lax weld conditioning are preventing 50-95% of the normal weld distortion and preventing 50-95% of weld cracking.  There are numerous other bonus benefits to using Meta-Lax weld conditioning like welding up to 25% faster, reducing (up to 300-F -150-C) preheat, reducing porosity, and more.

The reason why Meta-Lax can be used during welding is that the level of vibrational energy that Meta-Lax equipment uses is very mild and will not disrupt the welder during welding.  The weld metal tends to “pack down” as solidification occurs. Another important benefit of Meta-Lax Weld Conditioning is that in many applications it stress relieves the weldment, therefore, no additional post-weld stress relief is needed.
