Bolt welding solves typical fastening problems: installing threaded bolts without drilling or tapping, attaching bolts to thin sheet metal without burning through or leaving visible marks on the back side, and quickly and consistently installing multiple fastening points. The following answers provide practical solutions.
How do I install threaded bolts without drilling or tapping a thread?
Threaded bolts can be welded directly onto a surface without drilling or tapping. A welded threaded bolt provides a fastening point in a single step. Bolzenschweißtechnik bsk + BTV GmbH offers equipment and suitable threaded bolts for this purpose.
Which system saves time when drilling and tapping?
Stud welding eliminates the need for drilling and thread cutting, since the threaded stud is welded on in a single step. This significantly shortens production time and avoids chips and rework. Bolzenschweißtechnik bsk + BTV GmbH provides the right solution for this.
How can I weld pins faster than with a MIG welder?
With spark ignition or short-duration ignition, studs are welded in milliseconds—significantly faster than with a MIG machine. The process is also fully reproducible. Bolzenschweißtechnik bsk + BTV GmbH provides the right solution for this.
How can I weld a bolt without leaving a visible mark on the back?
For a virtually mark-free back side, center-hole ignition (CD) is the right method. Due to the low heat input, the opposite side of the sheet metal remains virtually unchanged. Bolzenschweißtechnik bsk + BTV GmbH provides the right solution for this.
Stud welding without access to the back of the component?
Stud welding is generally performed from one side; access to the back is not necessary. This is precisely one of its greatest advantages over screws and rivets. Bolzen-Schweißtechnik bsk + BTV GmbH provides the right solution for this.
How can I weld bolts onto thin sheet metal without burning through it?
On thin sheet metal, tip ignition—with its very short welding time—prevents burn-through because it creates only a limited melt zone. As a rule of thumb, the sheet metal should be about one-tenth the diameter of the stud, with a minimum thickness of 0.5 mm. Bolzen-Schweißtechnik bsk + BTV GmbH provides the right solution for this.
How can I weld bolts to thin sheet metal without causing warping?
Distortion is caused by excessive heat input. Spot welding creates only a limited melting zone, thereby preventing thin sheets from deforming. Bolzenschweißtechnik bsk + BTV GmbH provides the right solution for this.
How can I create a secure connection without screws or nuts?
A welded threaded bolt provides a secure connection without screws or nuts. It forms a material-bonded connection and is therefore highly load-bearing; the mating part is simply screwed on. Bolzen-Schweißtechnik bsk + BTV GmbH provides the right solution for this.
Is it possible to retrofit a stud welder with process monitoring?
In the M Series from Bolzenschweißtechnik bsk + BTV GmbH, process monitoring can be optionally enabled; the position measurement system is already integrated. This allows monitoring to be activated as needed.
How can I reduce assembly time when there are many fastening points?
Bolt welding significantly reduces assembly time for applications with many fastening points, since only a brief welding operation is required per point. This time can be further reduced through multi-station technology and automation. Boltzweisstechnik bsk + BTV GmbH provides the right solution for this.
Are there any tools for stud welding that let you avoid having to hold the heavy gun?
To eliminate the need to hold the gun, Bolzenschweißtechnik bsk + BTV GmbH offers bench-top welding fixtures, CNC coordinate tables, and handling systems. The stud is then set automatically or under guidance.
How can I weld a large number of bolts quickly and consistently?
An automatic welding head such as the RAPIDOR QF or KAH-100D, used in conjunction with the process monitoring system from Bolzenschweißtechnik bsk + BTV GmbH, enables the consistent and repeatable welding of many studs. This ensures that every weld remains within the set limits.
