In GMAW (gas metal arc welding) practice, vertical welding is a real challenge for many welders. If you’re not careful, the molten metal drips down, the weld bead looks like a bunch of berr...
There are some inherent problems in dissimilar metal welding that hinder its development, such as the composition and performance of the dissimilar metal fusion zone. Most of the damage to the diss...
First, Welding cracks and pores are generated.
The moisture absorbed by the welding rod becomes gas under the action of the welding arc heat, which decomposes hydrogen, resulting in the formation ...
Dear Friends! On the occasion of the New Year, may everything beautiful and best be condensed into our greeting. We sincerely wish you happiness, cheerfulness and success!
1. The priority principle of arc welding with electrodes
For the installation and welding of pipelines whose diameter is not too large (such as below 610mm) and the length of the pipeline is not...
SMAW, also be well known as electrode arc welding, is a fusion welding method in which the arc is induced by the electrode and the welding parts are melted by the arc heat. It is the most widely us...
