Many welding problems that show up on the shop floor—poor bead appearance, porosity, cracking—are often traced back to one overlooked factor: how the consumables were stored before they ever rea...
Cast iron is an early used structural material. Many parts of mechanical equipment are made of cast iron. At the same time, the repair welding of cast iron parts is still a common problem.

The welding residual stress is caused by the uneven temperature distribution of the weldment caused by welding, the thermal expansion and contraction of the weld metal, etc., so the welding constru...
Choosing the right welding wire is crucial for achieving strong, clean, and efficient welds. Two of the most commonly used welding wires in steel fabrication are Solid Wire (ER70S series) and Flux...
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...
