The quality of spot welding depends on the force applied by the electrodes as well as on the intensity of the welding current. Within such a control program, the measurement of the force applied by the electrodes is extremely important for ensuring constant production.
That is why we have developed this equipment to measure the closing force of the grips that may be used during the final stage or during periodic maintenance. The end-pieces are interchangeable and can be used to measure force with various shapes of electrodes, the minimum closing dimension being 0.12 in.
This new instrument leverages the robustness, quality and precision of the Centor instrument family, which are specially designed for mobile use in a production workshop.

Testweld™ Hand Held Electronic Force Gauge
An ergonomically designed hand held force gauge.
ADVANTAGES
User comfort "'Ergonomically" designed - for ease of use
One piece unit
Very high accuracy
Swivel head allows access to difficult to reach positions
As with all welding procedures, it is important to eliminate as many variables as possible in order to achieve optimum welding consistently over long periods.
Electrode force is one of the critical parameters in obtaining repeatable, reliable resistance spot welds.
Force can vary because of variable factory air pressure, water in the air lines causing air cylinders to deteriorate and loss of air pressure due to worn seals.
This self contained instrument uses a cell with a force sensor to provide accurate digital read out for auditing weld electrode forces.
Accuracy of this instrument is better than 0.2% and can be switched to read 0-2000 kg, 0-20.00 kN or 0-4400lbs.
In cases of difficult access the head of the swivel head gauge can be swiveled at least ±72º up or down and rotates at least ±90º. Once the desired position is reached it can be fixed by a simple hand tightened knob. A 90 mm long handle is provided for optional use with 2 mountain positions either in-line or at 90º.
A support wrist strap is attached to the gauge so that in the event that it is forced out of the operators hand by misaligned electrodes, it need not fall to the floor and be damaged.
|
|
Faults in welding tongs or incorrect process parameters in welding can result in production line waste or defective parts. Checking the electrode force periodically permits spark malfunctions to be detected at an early stage so that repairs can be carried out in good time.
The new Type 9833A test sensor allows precise and reliable measurements to be carried out with minimal electrode gaps. The built-in charge amplifier simplifies the task of mounting and helps to ensure the reliability required by the automobile industry.

The HF27 High Frequency Inverter precisely controls and monitors electrical AND mechanical weld parameters. Miniature welds are highly sensitive to small heat profile fluctuations in the resistance welding process. Overheating deforms and destroys parts, while under heating results in a weak, unacceptable bond. To achieve consistent, reliable welds of small to microminiature parts, precisely controlled heating is required. This necessitates superior control of the energy output.

Quick Purge - Pipe Purging Systems
In cases where purging is required to be fast as well as reliable, the Quick Purge Systems can be used.
These systems will typically purge 36" pipe diameters to below 0.1% oxygen in less than 10 minutes and all smaller pipes, correspondingly faster.
Description
Each Quick Purge is covered with heat protective materials on the inside, so that the high temperatures at close proximity to the weld do not damage the devices.
Three hoses are available, one for argon inflation and purge, the second for auxiliary purge and the third for gas exhaust via a purge monitor.
Operation
The system is connected to an argon hose and inserted into the pipe to be welded.
The spinal connection hose is shorter than with other devices, to keep the purged volume to a minimum. The majority of the volume between the two dams, is filled with a special heat resisting collar, to keep the purge time low.
After positioning the system the argon source is opened, the dams inflated to size and the interspace purged.
after a few seconds, the auxiliary purge line can be opened to ensure the fastest possible purge time.
In trials these devices have performed many high speed welds under these conditions.
Sizes from 8inch to 84inch (200mm - 2100mm)
Feedback off the end users of the quick purge have reported savings of up to 83% ! on the purge time!
Saves on purge gas, as the volume needed to be purged is greatly reduced.
This system pays for itself in a few welds!
So why struggle with "make do" systems.

Heat Resistant Pipe Purging Systems for pre-heated pipe welds.
When pre-heated ferric steel alloy pipe joints typically (5% CrMo) and some other types of steel and alloys are welded, particularly for high pressure pipework or for low hydrogen requirements, argon purging at the back of the weld is required. This is to eliminate the risk of coking and oxidation, leading to notching and eventual stress cracking under pressure.
After many years of trials and development, Huntingdon Fusion Techniques Limited has launched a range of variable diameter pipe purging systems.
Description
One model is available for each internal diameter. Each one is variable by approximately +0mm -12mm.
Using the well tried and proven Argweld® Pipe Purging System, the heat resistant version is totally covered in a special heat resistant material, which will withstand temperatures of up to 300 degrees C (572 degrees F) for 24 hours.
Operation
The system is connected to an argon hose and inserted into the pipe to be welded.
The spinal connection hose is long enough for the dams to sit at the outer edge of the pre-heated zone.
After positioning the system the argon is opened, the dams inflated to size and the interspace purged.
The purge will remain on during pre-heat and welding. It is advised for the removal of the systems prior to post-weld heat treatment.
In trials, the devices have performed many welds under these conditions.

Faster
The system is quick + easy to install. It can be positioned accurately and the dams inflate instantly. Purging time is a fraction of that required to purge by conventional methods.
Easy to Use
'Inflatable Pipe Purge Systems' simplify the process of inert gas purging, Training is Minimal.
Improved Quality of Welds
Leading to bright, shiny, coke and oxide-free welds very quickly. The process involved is highly reliable. It gives regular, controlled high quality results.
Fast Pay Back
The Argweld pipe Purging System pays for itself in just a few welds.
Fast Payback
The 'Inflatable Pipe Purge System' pays for itself in just a few welds.
Highest Standards
We manufacture to Nuclear Quality with Nuclear approved materials.
High quality circumferential butt welding of pipe to pipe and pipe to fitting requires inert gas to be used inside the bore to prevent oxidation and notching of the root penetration weld bead.
The best system devised for this is the Inflatable Pipe Purge System.
It is quick, reliable and easy to use, the volume of purging required is kept small, resulting in significant savings in both time and the volume of inert gas used.

Manufactured using a high quality latex inner tube and polyurethane impregnated nylon fabric outer cover
Installed with a length of flexible inflation hose with sealing tap/valve.
Styles:
Cylindrical inflatable stoppers do not 'turn over' in the pipe. They are commonly used for stopping off pipes, particularly where access is difficult. They are frequently used for testing new pipes and drains.
Spherical inflatable stoppers give less contact area than the cylindrical version, but are very useful when access is limited. Since the position of the inflatable stopper in the pipe is not critical, it can be put at any angle. This is particularly useful when inserting into a small opening at the top of a pipe, rather than at the end of the pipe.
Rectangular inflatable stoppers have various applications specifically in air conditioning systems, air ducting and venting.
All sorts of special shapes and sizes have been taken on as specials!
