The gun lifts the stud up from the work, drawing a pilot arc. High Strength Friction Grip Bolts 8. Arc stud welding is a pressure welding process.
A ferrule is placed into the 13981 grip. The drawn-arc stud welding has been firmly established for many years in the dn of head studs in composite construction and in the manufacturing of steel components in solid construction.
Upon request the properties of each can be documented by test report 2.

This process requires increased economy and safety. Download PDF Drawn arc stud welding – thin, coated sheet metal For stud welding of thin sheets here from approx.
The stud remains lifted for the duration set on the controller. Arc stud welding is a pressure welding process in which stud end and base material are melted by a short burning arc and then joined with low force. The ferrule is broken away and discarded.

In order to achieve perfect results, not only the materials, surfaces and devices must be suitable, but electrical processes must also be coordinated with the mechanical movement. Download PDF Safe stud welding in workshops and on building sites The amount of plunge also determines the degree of spring pressure plunging the stud.
See setting plunge in this booklet. Again there may be more recent versions of the document. The Amber document status indicator indicates that some caution is needed when using this document – it is either: This air-gap increases the electrical circuit resistance and generates the heat necessary to melt the stud and parent material for the weld. We can manufacture any type of typical Fasteners as per your drawing and specifications.

The pilot arc establishes a path for the weld current which comes on after the stud is lifted. In composite construction, it is izo possible to combine the positive properties of steel and solid construction without having to accept their disadvantages.
Technical information to make your welding technology even safer. They offer many advantages due to their compact and rigid construction, the simple fire protection with concreted chambers and the fast welding of the head bolts.
We are dedicated to provide on ne delivery at most competitive prices.
ISO 13918-1998 Threaded stud(PT)
If no gap exists bbs would be a direct short to the base material and sufficient heat would not develop. This represents the portion of the stud to be used in forming the weld fillet.
Bolt end and base material are melted by a bbs burning arc and then joined with low force. When the time set on the controller has elapsed, the gun plunges the stud into the molten pool of parent material and the weld is completed. They form the bond between a steel beam and a concrete slab, so that they work together. For stud welding 1918 thin sheets here from approx.
