Introduction
Proper storage of welding consumables is often overlooked — but it directly affects welding quality, safety, and cost.
Incorrect storage can lead to:
Moisture absorption
Porosity an...
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 ...
The coating plays a complex metallurgical reaction and physical and chemical changes in the welding process, which basically overcomes the problems in the welding of the photo electrode, so the coa...

Welding Arc Stability
AC Welding: The stability of AC arc is relatively poor. The direction of the alternating current changes periodically, and the arc will extinguish and re-ignite when th...
With the rapid development of the petrochemical industry, stainless steel materials have been widely used, which has also put forward higher requirements for the welding of pipes and plates. The pr...
Welding can use AC or DC welding machine. When using a DC welding machine, there are positive connection and reverse connection. Factors such as the electrode used, the condition of the constructio...
