When welding 6061 aluminum and its alloys with AC/DC TIG welding machines, ER4043 (Al-Si5) and ER5356 (Al-Mg5) are the two most commonly used filler wires. Although both wires look silver-white, ...
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...
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...
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 so-called welding skills are simple welding methods, correct electrode angle and operation, and your welds will not be too bad.
At the beginning of welding, due to the lack of mastery of the we...
