What defects may occur in welding large steel castings
2017-06-08 | Editor:
In the actual casting process, some large steel castings requiring a relatively fine processing may have use Segment casting methods. For this type of large steel castings, we have conduct welding treatment, but in the welding time, it will inevitably occurs for a variety of circumstances resulting some defects in large steel castings, affecting the quality of large steel castings.
Then, what are the possible defects in welding large steel castings?
1. Blow hole.
Blow hole happens when the welding position is not clean or the electric current is too large;
2. Cracks.
In the welding process of large steel castings, we should try to avoid cracks caused by improper welding operations, which are also the major defects in welding large steel castings;
3. Strength
After the completion of welding, perform tests for the strength of the welding posiion, and if the strength is too low, it will affect the quality of large cast steel parts.
In view of the defects that may occur in the process of casting, large steel casting enterprises should check the specific operation procedures and materials to avoid these defects during welding.
Great Wall Steel Casting Co Ltd, as a Chinese first-class large steel casting enterprises, not only possesses mature technology and experience in the welding of large steel castings, but also ia able to directly cast the steel pipe joints to make the steel structure stress is more reasonable and more stable. The stress on the whole structure caused by a great deal of concentrated welding is overcome.
