What is planishing a weld?
What is a Planished finish and how is it achieved?
It is first softened by a heat treatment process called annealing. It is cleaned before being planished. As the copper is 'planished', it is rotated on the stake. Planishing hardens the metal, ensuring the final shape (such as a bowl) has the strength to resist drops and knocks.

What is a planishing hammer?

How to tell if a hammer is stretched?
With the hammer striking so fast and hard on the metal it will eventually stretch the metal and you will notice the metal begin to develop a bulged area where the metal is stretched .
What is the handiest feature of a planishing hammer?
One of the handiest features of planishing hammers is their ability to crush welds completely flat, and to correct the distortion caused by welding.
How does a power hammer work?
A power hammer will most likely have a moving upper die and holder that can weigh upwards of 10 or 20 pounds, and it's operated by an eccentric crank that lifts this die and then literally throws it down against the lower die. Most power hammers have some sort of elastic material (usually leaf springs and fabric webbing) between the crank and the moving die, which allows the mechanism to store and release energy, something like "cracking a whip." This causes the dies to strike together with enormous force, and this will make the metal move in a hurry. Planishing is a much more delicate operation, better suited for smoothing rather than for big-time shaping.
What does planishing mean?
Let's start by defining the term planishing, which means to smooth by light hammering. Metalworkers have been planishing sheetmetal parts ever since hammers were invented. The basic idea is that hammering with relatively light blows will tend to smooth the metal, and as long as you use the proper technique, the metal won't become over-stretched.
Why do you need to swing a hammer?
You need to swing the hammer with enough force so that inertia causes the hammer to do some useful work. The moving parts of most pneumatic planishing hammers weigh just a few ounces, so it requires a lot of inertia for the lightweight die to move the metal. This is accomplished by oscillating that small weight rapidly.
How to planish metal?
The traditional way to planish a piece of metal is to work against a dolly block that has a shape close to what you want for the finished panel. You place a rough-formed piece of metal on top of the dolly, and hammer the metal so that with each blow, a small portion of the metal gets squeezed tightly between the hammer and dolly. Even if the metal is initially lumpy or wavy, the metal will smooth out with enough hammering, assuming the hammer and dolly have smooth surfaces, and as long as enough force is applied to exceed the elastic limit of the metal.
Do planishing hammers require compressed air?
While somewhat unusual, some very effective planishing hammers have been built that are completely mechanical, and don't require compressed air to operate. Check out the photo of the Mechammer in this article.
Do body hammers change metal?
Body hammers are fairly light, and if you just allow a hammer to fall from several inches above the metal, the light hit doesn't cause any change in the metal. You need to swing the hammer with enough force so that inertia causes the hammer to do some useful work. The moving parts of most pneumatic planishing hammers weigh just a few ounces, so it requires a lot of inertia for the lightweight die to move the metal. This is accomplished by oscillating that small weight rapidly.
