In carbon steels, low alloy steels, thick sections, restrained joints, and higher strength steels, preheat can be the difference between a sound weld and a delayed crack.

A weld does not fail only because of poor technique. Sometimes, it fails because the steel was too cold before the arc was even struck.

This article explains the role of preheat in welding, why it is important, how it helps prevent hydrogen assisted cold cracking, and why it must be treated as

“Wow, it’s amazing how wide it is.”

Let’s look at this critically. A wide weld pass, as shown in the video, leads to excessive heat input per unit area and increases transverse tensile residual stress at the weld toe, where fatigue cracks typically initiate. This stress acts normal to the fusion line and accelerates Mode I fatigue crack growth.

Fewer passes may save time, but the cost often appears later in the form of reduced fatigue life.

This welding technique represents a poor practice from a metallurgical and quality standpoint and should not be promoted or taught.
