What we have here is a few different nozzles. This isn't the total range of nozzles you can have from 2.5 up to whatever you test testing so you can have these on. You can even have these on shear studs, et cetera. Visual tests complete. You can now submit your weld it studs to a physical test, and one of these physical tests is carried out by abandoned by like this. So here we have a standard bending bar, which you can purchase for myself. There we go...
Today, we’ll be demonstrating a type of disruptive test. So this is a Bending bar and what we have here is a few different nozzles. Why do we use a bending bar? Bending bar is used after you’ve done your visual checks and you own your test piece.
There's six key areas studwelding replaces inserts. Inserts can work loose and studwelding makes your weld leakproof, and the weld formed is stronger than the parent material. Drilling and tapping is another area, so generally drilling and tapping is slow and withstood welding. It eliminates the need of penetration back welding again, a slow, messy and inaccurate process.
The CDM8 will weld up to and including 8 millimeter threaded CD weld studs. We've got such a wide customer base from many different industries, so we've got, you know, anyone that's working with sheet metal, anyone we're working with and close enclosures, metal enclosures that need earthing. We have got a quick example here of a PCB, so you can see that underneath the plastic spaces. We have got more steel studs welded in here, and that's how this PCB has been attached to this inside this metal enclosure. We've got a CD welded Earth tag here showing the Earth is in and out that's been CD welded so that you can do that with the CDM8 as shown here.
People have different names... Collets is a common one, so it's chucks you'll hear mostly. Chucks are the most common used terms, but you might also hear:
All these terms are used to describe the (usually soft copper) holder inside the hand tool, essential for maintaining good quality welds. We will explain how to keep good quality welds in the video below
With the Capacitor Discharge Process energy is stored in a bank of capacitors, which are charged to a pre-set voltage, determined by the type and size of stud and the parent material. When triggered...View CD Process
A transformer rectifier supplies a fixed current power source, triggering produces a pilot arc and the stud lifts to a pre-set height.The main arc melts the end of the stud, producing...View SC Process
With this process, the current level and weld duration are determined by the stud diameter. Triggering produces a pilot arc and the stud lifts to a preset height. The main arc melts the end of the stud, producing a molten...View DA Process
