Detailed explanation of spot welding process
01.Brief description Spot welding is a resistance welding method in which welding parts are assembled into lap joints and pressed between two electrodes, using resistance heat to melt the base metal to form solder joints. Spot welding is mainly used in the following aspects: 1. Overlap of thin pl...Read more -

How to choose the feed and speed of reamer in machining center
Selection of Reaming Amount ⑴ Reaming allowance The reaming allowance is the depth of cut reserved for reaming. Usually, the allowance for reaming is smaller than the allowance for reaming or boring. Too much reaming allowance will increase the cutting pressure and damage the reamer, resulting in...Read more -

The difference between fixed welding joint, rotating welding joint and prefabricated welding joint in pipeline welding
Rotation welding corresponds to fixed welding in pipeline welding. Fixed welding means that the welding joint cannot move after the pipe group is aligned, and the welding is performed according to the change of the welding position (horizontal, vertical, upward, and mid-level changes) during the ...Read more
