We, the team of the SLV Munich, research and develop since over 40 years in the field of stud welding. From long-standing and tight cooperation with users, contractors and machine manufacturers we have a comprehensive know-how available for you.
Within courses and procedure testings according to DIN EN ISO 14555 operators and welding supervision personnel can qualify in the area of stud welding (arc stud welding and friction stud welding)
We offer the following services:
Also ask us about individual training for you and your employees!
Pin-shaped metallic components with diameters up to approx. 25 mm are fastened on base sheets vertically by means of stud welding. Different procedure variants are available for the most diverse applications.
In the case of arc stud welding, an arc burns between the front face of the stud and the workpiece for a short time and partially melts the joining members (stud and sheet). After sufficient partial melting, the molten pools are connected with each other by the stud movement towards the sheet.
Depending on the procedure variant, the stud welding industry offers suitable power sources, movement jigs, studs and additional auxiliary materials (e.g. ceramic ferrules). The handling is comparatively simple but a large number of welding and boundary conditions must be coordinated in practice for successful and safe fabrication.
In our laboratory rooms, we have at our disposal stud welding installations for the drawn arc and initial contact procedures as well as for the friction stud welding of various designs and sizes.
In this respect, the performance range of the installations extends from thin pins (approx. 2 mm) to massive head studs (approx. 25 mm).
The field is looked after by three people (two engineers and one technologist).
Examinations on the decrease of the angular position at the stud welding with arc ignition
Our equipment originates from reputable manufacturers from the area of stud welding. Thereby we want to thank in particular our partner for the good cooperation:
The available equipment are on the state of the art technique, like power sources with inverter technology up to 2800 A, welding heads with linear motor as well as improved solenoid spring principle and optimized shield gas devices. but also additional tools, e.g. for the magnetic influence of the arc at the stud welding on full cross-sections als well as hollow cross-sections (bush welding respectively nut welding) can be used according to the welding assignment.
