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...
Welding work involves many industrial fields, welding fume is one of the most common hazards of welding work.
Welding fume is in the welding process when the welding rod and welding parts in contac...
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...
The thermal conductivity of copper and copper alloys is more than 5 times that of carbon steel. Welding is prone to pores, lack of fusion, and thermal cracks. The selection of welding wire direc...
