Examining the X-factorThe X-factor, also known as the Bruscato factor, is an important equation for anyone welding with chrome-moly steel. The equation will help you test your filler metals for levels of phosphorus, antimony, tin, and arsenic that could make a weldment susceptible to temper embrittlement.

The lowdown on low-alloy filler metalsWhen welding a chromium-molybdenum alloy, selecting the optimal filler wire is critical to the long-term durability of the weld. Fortunately, matching the filler metal to the alloy is no more difficult than it is for matching a filler metal to any other family of alloys. Understanding the...

Start with the basics: Understanding flux-cored wiresArming yourself with basic information about flux-cored wires can help you decide if these consumables are right for your welding application. Available in gas-shielded and self-shielded, flux-cored wires require less skill to use than other filler metals and commonly are used for general...
