In steel structure fabrication, flat position welding is the most basic and commonly used position, and it is also the easiest to achieve good weld quality. Although flat welding is relatively les...
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 defects can be divided into two main categories based on their location in the weld: internal defects and external defects.
External defects are located on the outer surface of the weld an...
