Carbon Equivalent (CE) is a key factor that decides how easily steel can be welded. In this short video, you’ll understand what CE means, how it is calculated, and why higher CE increases cracking risk. Learn how alloying elements like carbon, manganese, chromium, nickel, and molybdenum affect weldability. We also explain CE ranges, when preheating is required, and how proper cooling control improves weld quality. This knowledge helps welders, inspectors, and engineers avoid weld defects and mak

SOLIDIFICATION CRACKS IN WELDING 🔧 Solidification cracks are hot cracks that occur during weld metal solidification due to the presence of low melting point impurities. Visit weldfabworld.com 🔹 Crack Mechanism Low melting point elements such as Sulphur (S) and Phosphorus (P) segregate at the grain boundaries during solidification, reducing cohesion and leading to cracking. 🔹 Example Iron Sulphur → Iron Sulphide (FeS) Iron sulphide has a low melting point, which promotes solidification crackin

If you leave a big crater at the end of your aluminum welds it leads to Cold Cracking that will spread. To fix it you want to make sure you change your work angle and sit to make sure it fills up. If you are having issues with welding aluminum with a spool gun check out @whiteriverrambo breaking down common issues over on YouTube. #spoolgun #cracks #coldcracking #aluminumwelding #migwelding #welding #welddotcom

The Biggest Risk Visit weldfabworld.com 1. Prevention of Cracking (Most Critical) The primary reason engineers require hardness testing is to avoid Hydrogen Induced Cold Cracking (HICC). Hardness vs. Brittleness: When a weld cools rapidly, it can form a very hard but brittle microstructure called Martensite. The "Trap": If the hardness is too high, hydrogen (from moisture or contaminants) gets trapped in these brittle areas. Under stress, this leads to sudden, delayed cracking. Control: Industry

Here is an example of a root bend for a 1FG SMAW CWB test. This is what you want to see after the bend, no indication of non-fusion or slag inclusions that can show up on the root face or via corner cracking on the sides.
