Welding stress and distortion is the stress generated in welded components due to welding. It includes internal stresses generated during the welding process and changes in shape and size cause...
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...
Ⅰ. Start up
1. Turn on the power switch on the front panel and set the power switch to the “ON” position. The power light is on. The fan inside the machine starts to spin.
2....
Welding current, voltage and welding speed are the main energy parameters that determine weld size.
1. Welding current
When the welding current increases (other conditions remain unchanged), the pe...
No matter where the welding joint is, it is actually an accumulation of welding experience. For novices, simple positions are the basic exercises, starting with rotations and moving on to fixed pos...
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...
