1. What is the purpose of steel annealing?
Answer: ①Reduce the hardness of steel and improve plasticity, so as to facilitate cutting and cold deformation processing; ②Refine the grain, uniform the ...
There is no difference in process between full argon arc welding and argon arc welding. Full argon arc welding is suitable for thin-walled small-diameter pipes (generally DN60 and below, wall thick...
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...
The preparation work before welding is as important as the welding process, which is directly related to the welding quality and effect of the finished product.

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...
