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 ...
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...
1. Core principle: Why must we use argon?
During the welding process, the metal is like red-hot iron at high temperatures. If it is not protected, it will immediately combine with the oxygen and ...
Introduction
Aluminum welding requires the right filler material to ensure strong, crack-free joints and excellent corrosion resistance. Among the most widely used aluminum welding rods are E4043...
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...
