When engineers plan the welding process parameters, the weld nugget size is the key factor to optimize. But weld quality is not only about the weld nugget size. It is also important to get high weld strengths and good material properties around the weld. In this case study, we present the influences of the hold … Continue reading
Liquid metal embrittlement(LME) is a phenomenon where certain metals like Al and steels undergo brittle failure when stressed in contact with liquid metals like Zn, Sn, Pb, etc. One of the challenges in the welding industry is cracking due to LME observed on spot welds of Zn-coated High Strength Steel. Liquid zinc penetration results in … Continue reading
