Defects - Solidifiion Cracking - TWI
Welding with contaminants such as cutting oils on the surface of the parent metal will also increase the build up of impurities in the weld pool and the risk of cracking. As the compositions of the plate and the filler determine the weld metal composition they will, therefore, have a substantial influence on the susceptibility of the material to cracking.

Here, we tested the breaking strength of welded Cu-Ga-In/fibers with inner core of UHMWPE fiber at low temperature (8 C). The breaking strength of welded Cu-Ga-In/fibers gradually increases with the welded length of two fibers, and the maximum breaking strength is about 15 N with welded length of 20 mm, as shown in Figure S8A.

How to Avoid Cracking in Aluminum Alloys - ESAB
When welding base alloys with below 2.5% Mg it is necessary to change the chemistry of the solidifying weld from the high crack level of the base alloy. We alter the chemistry of the weld by selecting a filler alloy with a much higher content of Mg, such as 5356 (5.0% Mg) or …
Welding For Dummies Cheat Sheet - dummies
During mig welding, one of the most common causes of excessive spatter is using too much wire. If you’re getting spatter everywhere during a mig weld, try slowing down your wire feed speed. If that doesn’t work, the excessive spatter might be the result of arc blow, which occurs when magnetism in your base metal affects the quality of your arc.
