WELDFAST® has revolutionized assembly technology in virtually all areas of sheet metal fabrication: Automotive Industry, Agricultural Industry, Boiler Construction, Process, Production Engineering, Heating, Ventilating and Air Conditioning, Sanitation. In short, every-where, where brackets, hooks, angled pressings are needed for mounting and assembly.

Metal pressings of complex shape can be welded directly onto a surface. It is as simple and effective as stud welding and can be automated too!

Less material, less weight!

Unlike resistance spot welding no additional flanges on the parts are needed. So, less weight, lower costs!

Simplified assembly!

WELDFAST needs only single side access, whereas spot welding requires access to both sides - benefits in process, tooling and access.

Easily automated!

WELDFAST is ideally suitable for assembly robots. After automated supply to the gripper weld head, the parts will be positioned and welded in one simple work step.

Fast and precise!

The welding robot can position up to 10 components in only 3.5 minutes, precisely in position, without a reference point on the base sheet and without prior location fastening!

A safer weld joint!

A WELDFAST weld joint is not just point-welded, but is fully attached across the entire surface of the complete cross-section, resulting in higher carrying capacity. Parts can be kept smaller and savings maximized!

WELDFAST. The procedure.

For 4-Phase Safe Weld Joints. Short-term welding with drawn arc process description. Component is placed on the base sheet Pilot current (lr=20 to 50 A) is switched on and the component is lifted - a pilot light arc is created. Main current (500 to 2000 A) connection - the intensity of the arc is increased, the material is melted. The component is plunged into the melt, the welding current is cut off.

WELDFAST. The system.

The WELDFAST system allows multiple configurations to be integrated into manufacturing lines for manual, semi- and fully automated operations. System control is performed depending on the task via PC/Laptop.

The LM weld head.

The LM weld head is based on stud welding technology. Its linear motor drive guarantees the precise and accurate repeatability of defined lift heights and a variable-speed dampened plunging process whilst maintaining constant, individually adjustable clamping pressure. Through electronic real-time adjustment, the system will react immediately to differing component geometry; even the slightest variations in tolerances will be compensated for automatically. Depending on the component to be welded on, the weld head is equipped with either spring grippers or a pneumatic gripper system. An optional inert gas supply is possible.

The control and power unit DCE MAX.

A powerful energy source adjustable between 380 and 500 Amps. The supply feeding process. Smaller components are directly supplied to the weld head via a feed hose, as is the case with studs. The weld head, connected to a robot, take larger fastening elements from a magazine or spool feed.
