Silversmithing applications

Can solder be used as a substitute for welding?
Solder tends to burn during welding due to its additives, so it is not suitable as a filler metal. Also, if possible, do not weld at solder joints, or alternatively, […]
Welding silver: what to consider?
Metals with high thermal conductivity are generally difficult to weld, but: The thermal conductivity of silver decreases as its temperature increases. This means that silver can be welded better when […]
When to solder, when to weld?
In principle, soldering – where usefully applicable – is usually considered the ideal joining technique in jewelry manufacturing. Nevertheless, there are a variety of applications in jewelry making and repair […]
How does the spot weld change when you change the time?
The pulse time is mainly responsible for the penetration depth of the spot weld. The longer – the deeper. For very thin material, always work with the shortest possible pulse […]
How do the spot welds change when you change the power?
In general, it can be said that the power controls the diameter of the spot weld. Although higher energy also increases the penetration depth of the weld puck, the welds […]
Up to what sheet thickness can workpieces be welded? Max. Penetration depth
If the material thickness of the workpiece at the fracture point is greater than 1.0 mm, the penetration depth of the welding device is not sufficient. The fracture must then […]
What is the time interval between two welding spots?
The time between two welds is 0.8 to 2.0 seconds. It automatically adjusts to the operator’s working speed. I.e. with a fast welding sequence, the time span is automatically reduced […]
Is argon toxic?
It is a noble gas and a natural component of air. Like all noble gases, it does not react: it cannot burn and is not toxic. Nevertheless, care should be […]
How long does a 10 liter argon bottle last?
In an average goldsmith’s workshop, one filling of a 10-liter bottle will last for about 6 to 12 months, depending on how intensively welding is done with the PUK.
