Welding Studs

Welding Studs:

1. Brief Introduction:

Stud welding means the direct welding metal studs or similar metal fasteners (studs, anchor parts) to the work piece (the base material, generally the plate), featuring higher speed and strength, smaller heat-affected zone and less pollution, which is generally used in various aspects as the automotive, boiler, construction steel structure and ship building.

Threaded fasteners, common pins, open pins and studs can be used in this method with nonferrous metals as low carbon steel, low alloy steel stainless steel and copper.

Welding current (Ampere) can be selected from the range of 50—100 times of the stud diameter.

That is I=（50-100）d（A）.

Welding time (Millisecond) can be selected from the range of 50—100 times of the stud diameter.

That is I=（50-150）d（ms）.

The welding reference values of construction steel stud we recommend are from our past experience, and the specific requirement in the work shall be determined by the experiment in the actual conditions. Besides, the following experience data is for the stud of low carbon steel, thus other process experiments shall be made for other materials.
