Hi All,
I have posted something similar under the section "material and metallurgy engineering", titled: Welding Issue.
As far as concern, the comments were beneficial, stating that the welding was lacking of fusion and penetration (see attached).
However, I have another concern. Does corrosion play a part in the welding failure? In the picture, the corrosion came in different colours (light brown, dark brown). Any indication? In addition, from the surface, could anyone be identified whether the surface was overheated, or it is purely corrosion?
Background:
1. Supporting bracket, that is able to hold the weight of 100 kg.
2. The supporting bracket is made of mild steel, corner joints at 49 degree
3. It was dipped coat with hot galvanising zinc.
Thanks.
