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, […]
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 […]
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 […]
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 […]
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 […]
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 […]
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 […]
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 […]
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.
