short cycle stud welding machine stud welder for M3-M12 welding studs

The process “short cycle Stud Welding” is used for welding studs of a diameter of 3 to 12 mm onto thin sheets. The minimum thickness of the sheet is 1/8 of the stud-diameter. This process leads to a flat weld penetration. For this reason, short cycle stud welding is mostly used for welding studs onto thin sheets. Generally, studs with a flange and a flat apex without any addition of aluminium are in use. In general, the positive pole of the power-source is connected to the workpiece. The stud will be inserted into the chuck of the Stud Welding Gun and positioned onto the workpiece, possibly by adding a Ceramic Ferrule. Initiating the welding process: by means of a lifting mechanism, the stud will be lifted and at first an auxiliary arc (pilot arc) of a low current will be drawn. Then the main arc will be drawn between the tip of the stud and the workpiece. The main arc of a high amperage must be adjusted to the diameter of the stud. The cross sectional area of the stud and the opposite workpiece a partially melting. After the lapse of the adjusted welding time, the stud is moved towards the work piece and both melting zones join tightly. The power-source turns off, the melting zone solidifies and cools down.
