As any contractor knows, most jobs sites are far from being clean, dry or orderly—at least for any length of time. Unfortunately, the environmental conditions on the average job site can wreak havoc on welding filler metals, and in turn on a contractor’s overall productivity […]
Through the addition of particular alloys, low alloy steels possess precise chemical compositions and provide better mechanical properties than many conventional mild or carbon steels. These alloys typically comprise one to five percent of the steel’s content and are added based on their ability to […]
Whether the result of poor parts fit-up, rapid cooling or a variety of possible contaminants—from the atmosphere, base material or filler metal—weld cracking carries with it significant consequences for any welding operation. Not only does this defect adversely affect the integrity of the finished […]
As the world’s energy demands continue to grow and new sources of fuel are sought, it’s no surprise that contracting companies have begun to expand the use of stronger, more cost-effective materials to build longer and more remote pipelines—both onshore and offshore. Instead of X70 steel pipe, the standard in past years, material like […]
The hostile environment in power generation plants present ample opportunity for weld repairs. In coal-fired power plants particularly, the steam-generating tubes of a boiler inevitably corrode over time, requiring scheduled shut downs to remove and replace damaged sections. Weld quality on these repairs – because of the extreme temperatures […]
