1. Reduce stress concentration The stress concentration point of the fatigue crack source on the welded joint and structure, and all means of eliminating or reducing stress concentration can improv...
Argon tungsten arc welding uses argon as a shielding gas to heat and melt the welding material itself (it is also melted when the filler metal is added) by means of the arc generated between the tu...
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...
The welding electrode is a metal rod that is melted and filled at the joint of the welding work-piece during gas welding or electric welding. The material of the electrode is usually the same as th...
The selection and preparation of tungsten electrodes for GTAW is essential to optimize results and prevent contamination and rework. Getty Images
Tungsten is a rare metal element used to make gas t...
Shielded Metal Arc Welding (abbreviated as SMAW). The principle is: an arc is generated between the coated electrode and the base metal, and the welding method using the arc heat to melt the electr...
