Perhaps nothing sends a chill down the spine of a professional welder like seeing weld cracks in their work. Welding cracks are not only frustrating for the welder and engineer, they also waste time and material. Welding quality is always a topic of conversation around metal fabrication shops including here at Wiley Metal. Projects that use multiple alloys are always closely monitored. While our goal is perfection, welding is still mainly a human endeavor, especially when it comes to challenging welds and projects. That can lead to the flaw or occasional crack.
Types of Cracks
Welding cracks generally fall into two broad categories, hot cracks and cold cracks. Hot cracks are formed while the weld and material are cooling. Cracks that occur later are called cold cracks. In determining why cracks occur, our engineers will often look into weld design, weld location and even into metallurgic makeup of the material(s) used. This is where experience really comes into play. The more welds that a metal fabrication company performs and the more differing metals and alloys a fabrication company is used to dealing with, the more likely they have determined how to minimize cracks of any type.
Fatigue and Corrosion Cracks
Over the course of time, fatigue and corrosion cracks can occur. While technically cold cracks, it is unfair to place corrosion or fatigue cracks into a category where cracks occur within months of a piece being produced. These are more likely to occur because the necessary long-term strength of a weld wasn’t initially produced or premature corrosion of the weld occurred for a variety of reasons. Again, these can best be prevented by an experienced team of skilled welders and engineers who fully understand the dynamics of how metals, alloys, and welds work in concert to achieve the optimum welding quality that will last for the long-term.
You are only as Strong as your Weakest Link
There is an old expression that your product, company or team is only as strong as your weakest link. There may be no greater example than in welding. While many view welds as a potential source of failure, at Wiley Metal, we view them as a source of strength. We take on our welding projects determined to make sure our welds won’t crack or fail and instead, actually add to the strength of the piece we produce. Our engineers and welders are dedicated to make sure every weld that leaves Wiley Metal will meet and exceed expectations both in the short and long term. In fact, we guarantee it.
Our Quality Weld Team Avoids Cracks
It’s pretty simple. Since cracks are such a source of exasperation for our team of welders, engineers, and quality control folks, we work together to avoid them at all costs. We are not perfect but we have decades of experience to rely upon. Welding is all about skill, experience, metallurgy, and engineering. You can count on the Wiley team to deliver for you. Let us know what we can do for you.
