Ⅴ. Welded Sample View
What is HF welding ?
High frequency (HF) welding is the joining of material by supplying
HF energy in the form of an electromagnetic field (27.12 MHz) and
pressure to the material surfaces to be joined. A generator
produces the energy. The tool used to supply the energy is called
an electrode. The electrical energy causes the molecules within the
material to start moving, which generates heat that causes the
material to soften and thereby fuse together. No outside heat is
applied. It is instead generated within the material. After cooling
the welded surface under maintained pressure, the material is fused
and a weld has been created. The weld seam can be at least as
strong as the surrounding material or even stronger.
Four important factors that affect the final weld result are
pressure, welding effect, welding time and cooling time. These
parameters can be adjusted and combined in different ways to
achieve the optimal welding result for a specific material.
The material most commonly used with HF welding is PVC (polyvinyl
chloride), sometimes called vinyl and PU (Polyurethane). The
material can be thick or thin, reinforced or coated. It can also be
plain, coloured or patterned.
ConnieWeld customers manufacture a great variety of end products in
these materials, such as truck and boat covers, tarps, tents,
structures, pool liners, sunshades, billboards, inflatable
products, liquid tanks, film screens, waterbeds, stetch ceilings,
valve membranes and oil booms.
Why HF ?
Below we have provided some comparisons between HF welding and a
few alternative joining techniques.
Hot air/hot wedge
Two alternatives to HF welding are welding with hot air or hot
wedge. These techniques involve heat being transferred to the
material surfaces from the outside and are limited to thin sheets
of material because the heat must be transported from the outer to
the inner material surfaces in order to fuse them. If the material
is too thick, it takes time and the outer material surfaces will be
overheated before the inner ones have been heated sufficiently.
The HF technique overcomes this problem because the electrical
field that generates the heat in an HF welding machine has the
highest effect in the centre of the sheets being welded. This
eliminates the risk of overheating and damage to surrounding
HF is also faster and produces a more durable and more uniform
weld. HF welding does not discharge any gases and consumes less
energy, which is better for the environment and of course saves
Compared to gluing, HF welding saves a lot of time and produces a
seam that is significantly stronger than a glued seam. Customers of
ours in the advertising industry in the Middle East have switched
to our machines for this very reason – burst seams caused glued
billboards to fall down in strong winds, resulting in personal
injury. HF welding also eliminates the use of adhesive, which
contains solvents that could be harmful to production personnel and
is not good for the environment.
Materials joined with a sewing machine are of course held together,
but are neither air-tight nor waterproof, which are often mandatory
requirements for products like tents or products that are designed
to be filled with air or water. When a sewn joint is stressed, the
load is put on the thread holding the joined material together.
However, when an HF-welded seam is stressed, the load is absorbed
by the material surfaces, which of course means that the HF-welded
seam is stronger. Furthermore, the seam created with HF can be
welded in a manner that provides a uniform transition without
splices between the joined materials. There is no space through
which dirt, moisture or bacteria can penetrate and impair the
product’s strength and durability.
