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...
The appearance of the weld matters just as much as its strength. Many of us have been there—the root pass looks great, but when it comes to the cover pass, the weld ends up dark, rough like sandpa...
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...
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...
