Short Cycle SC Studwelding

Short Cycle

A transformer rectifier supplies a fixed current power source. The main application for this process is with Mild Steel studs but it can also be used with Stainless Steel.

Low Cost Studs
CD studs may be used
Low Cost Equipment
Tolerates Surface Irregularities

Easy to Jig
No Ferrules required
Can be Bench Mounted & Automated

Greater stud design flexibility
as this Studwelding process does not require a CD pip

The SC Weld

Triggering produces a pilot arc and the stud lifts to a preset height. The main arc melts the end of the stud, producing a molten pool in the parent material. Return spring pressure then forges the stud into the pool. Using a shrouding gas reduces weld spatter especially when welding Stainless Steel.

Spring Presses Stud to Molten Pool
Shrouding Gas Recommended

Weld duration 10 to 100 milliseconds.

Short Cycle Studwelding provides greater penetration into the workpiece than CD.

The main application for this process is with Mild Steel studs but it can also be used with Stainless Steel.

The controllers are still portable but of medium weight compared to the CD controllers described above. The equipment is of lower cost than Drawn Arc equipment and requires a 3 phase supply 380/415volt 50Hz.

Requirements

This process should be used when the surface is uneven and where the parent material is greater than 1.7mm.
