The new Photonweld laser stud welding machines.

Strength that leaves its mark without any mark on the backside

Developed for tough construction site use and continuous operation, the machines deliver first-class welding results thanks to their high duty cycle, constant current control and modern microprocessor control - even in adverse outside temperatures and long cable runs.

This is a welding method where metal pins, bolts, studs, or other small parts are quickly and intensely welded onto a metal surface. 

Our advanced Laser stud welding machine, is highly suitable for precision and markless stud welding with diameters from 1.0 to 12.0 mm and lengths up to 50 mm.

Laser welding studs

Laser Spot Welding of Studs and Rivets with PhotonWeld Lite-Pro-O

Due to a fast increasing number of enquiries about studs that have to be applied using laser welding, many manufacturer of welding studs started to produce typically laser welding studs. Specific Laser welding studs have been developed in such a way that they are similar in dimension to welding studs for tip ignition. They simply leave off the ignition tip and the slight pitch, so that they can be welded flat on the sheet.

Stud welding can be used everywhere in metal construction and the metalworking industry and has proven itself for decades in welding threaded studs, internal threaded bushes or pins securely and cost-effectively to sheet metal - "Stud welding creates invisible connections".

Range of application extends from steel construction, bridge construction, composite construction and facade construction to power station, industrial furnace construction, general mechanical engineering and apparatus construction, vehicle construction and shipbuilding, boiler construction, tank construction and plant engineering to the household and electrical industries.

Laser Stud welding

Laser Stud welding, is a form of high efficient and low energy cost welding in which a stud or bolt is permanently connected to the workpiece. The bolt is attached to the workpiece by means of a laser welding gun.  This is a welding method where metal pins, bolts, studs, or other small parts are quickly and intensely welded onto a metal surface. 


Our advanced Laser stud welding machine, is highly suitable for precision and markless stud welding with diameters from 1.0 to 12.0 mm and lengths up to 50 mm.

With laser stud welding, not only can use be made of bolts, but also small bushings with internal threads. The advantage of the laser stud welding method is the high processing speed, the welder can weld several pieces per minute. There is also almost no heat distortion because the heat is applied very shortly and very locally and the piece cools down quickly. Due to the different methods exisitng, capacitor stud welding and arc stud welding, both types of studwelding can be replaced and thin and thicker material can be welded by laser stud welding.

Laser Stud Welding - unrivalled economic efficiency

Laser Stud Welding is a particularly economical welding process for joining round-shaped metallic parts (studs / welding studs / welding elements) with metallic workpieces such as sheet metal, profiles and pipes.

Every day, millions of welding studs are joined via stud welding processes in many areas of the metal industry. The simple handling of the equipment technology plays a significant role in the spread of stud welding. 

The decisive factors, however, are the design and economic advantages (see Table) for the connection "screw to sheet metal" compared to other welding and fastening methods (such as: Metal inert gas welding process (MIG/MAG/WIG), Clinching / Riveting, gluing,..)

High Profitability
Huge savings in costs and time 

Construction Advantages
New design possibilities 

Preparation:  

  • Only one step (no drilling, countersinking, tapping)

High strength joint

  • Complete surface area coverage 

  • High strength joint (welded connection higher then the strength of the stud and work piece)

Only one sided access is necessary

Weldable on very thin metal thicknesses

Different material combinations possible

High quality welding process: No riveting, gluing, screwing
 

Production 

  • Simple, speedy handling = High Productivity

  • Easy to automate

  • High duty cycle through very short welding times (max. 1s)

Post Welding 

  • Coating on the rear remains under certain conditions (no thermal marking) 

  • Backside of high-alloyed sheets unchanged under certain conditions (no geometric marking) 

  • Very short welding times minimize thermal energy input and thus distortion or backside markings 

Welding Elements / Studs

  • Low costs through the use of standardized studs / welding elements

Welding Elements / Studs
 

  • Besides huge range of standardized welding elements / studs application and customer specific studs / welding elements possible
     

Equipment Technology

  • Comparitively low aquisition costs combined with unbeatable cost/benefit ratio
     

Equipment Technology

  • mobile, compact and easy-to-use

Stud welding is in many areas the most economical joining technique for fastening screw- or stud-shaped components and often the only technical solution for joining elements to thin sheet metal.
