At present, argon arc welding still occupies the
mainstream in welding thin plates. For example, customers
in the door and window industry use argon arc welding
which is simple and convenient. However, argon arc
welding has low welding efficiency and requires welder
skills. Many customers, especially those with thin
plates, have relatively scarce welding skills and high
technical requirements, which has led to an increase in
enterprise labor costs. If you encounter a welder with
poor skills, the product will be scrapped.
As laser handheld welding products continue to mature,
the advantages of handheld laser welding are more
obvious. Laser welding efficiency is high, and the
welding speed is several times that of argon arc welding.
At the same time, the welding quality is high and the
deformation is small. The most important thing is the
technical level of the operator. The requirements are not
high, especially in the sheet metal industry. You can get
started with air-cooled laser welding through short-term
training. The technical requirements are lower, which is
more conducive to reducing the cost of recruiting and
employing people.
Handheld laser welding is a new welding method that has
emerged in recent years. It is easy to use, efficient in
workmanship, and has beautiful welds. It can realize
various processes such as electric welding, butt welding,
and sealing welding. With an intelligent control system,
precise welding control can be easily achieved. At
present, handheld laser welding has been widely used in
many industries such as kitchen and bathroom, home
appliances, furniture, doors and windows, advertising,
etc. The wave of intelligent manufacturing is
unstoppable.
After the introduction of air-cooled laser handheld
welding machines, welding equipment has become more
abundant. Comwelder laser relies on the advantages of the
Comwelder brand. Comwelder laser is in the first echelon
in China. Comwelder chooses to cooperate with larger
manufacturers. Product sales are only the first step, and
after-sales service is guaranteed. It is also very
important to choose a big brand, which means more
reliability and peace of mind.
Talking about the potential for the future development of
laser handheld welding, Comwelder believes that laser
welding has several core advantages: maintenance-free,
lightweight and portable, and reducing operator fatigue.
In the future, laser handheld welding will become an
increasingly important welding tool in the market.
Laser processing and manufacturing have experienced rapid
development in the past decade. One of the important
factors driving market growth is the replacement of
traditional technology with lasers.
From previous methods such as silk screen printing and
knife engraving, we have transitioned to laser marking
and engraving. Similarly, we have moved from punch and
blade cutting to laser cutting, and from chemical agents
and pickling to laser cleaning. All of these are
significant changes in technology.
The use of lasers has not only brought technological
progress but has also aligned with the trend of
industrial technology development towards environmental
protection and green manufacturing. By making processes
more efficient, increasing output, and improving the
aesthetic appeal of products, we can achieve a more
sustainable future.

Rapid rise of handheld laser welding
In terms of welding, there has been a shift in the
process from traditional electric and arc welding to
laser welding, which is currently the most important
application for metal materials.
Although laser welding has been in development in China
for nearly 30 years, the previous low-power YAG laser
welding machines were typically single machines, with low
degrees of automation, manual loading and unloading, low
power, small worktable formats, and difficulties in
operating on large parts, which hindered the spread of
laser welding applications.
In recent years, laser welding has made significant
progress, particularly with the application of fiber and
semiconductor lasers. There have also been developments
in workpiece fixtures, automatic control, and automatic
loading and unloading.
Nowadays, high-end automatic laser brazing systems have
been equipped in some automobile factories, and it is
also used in aviation parts, the locomotive body of CRRC,
and other industries.
Furthermore, power battery laser welding for new energy
vehicles has become a crucial application of laser
welding.
All of these examples illustrate the high-end
applications of laser welding.
By the end of 2018, handheld laser welding began to gain
popularity due to the significant decrease in the cost of
fiber lasers and the advancement of fiber transmission
and handheld welding joint technology.
The unexpected rise in demand for handheld laser welding
led many manufacturers to start producing these machines
in 2019. It is estimated that hundreds of enterprises are
now producing handheld laser welding machines.
One reason for the rapid popularity of handheld laser
welding is its convenience and ease of use. Compared to
high-end automatic laser welding, which requires advanced
technical knowledge and expertise, handheld laser welding
has a lower technical threshold and can be operated
manually without the need for fixtures or motion control.
Workpiece alignment and alignment clamping are done by
hand.
While some may view this as a regression from automation
to manual operation, it is important to consider the
actual application cost and acceptance. Overall, handheld
laser welding has proven to be a practical and accessible
alternative to high-end laser welding for many
manufacturers.
Taking stainless steel welding as an example, there are
currently a wide variety of welding processes available,
but the most common ones are ordinary argon arc welding
and spot welding. Despite years of development, manual
welding operations are still widely used, and there are
many such welders in the industry.
Argon arc welding is a popular choice for welding
kitchenware, kitchen supplies, bathroom hardware,
stainless steel doors and windows, anti-theft nets,
stainless steel furniture, hotel decoration, and other
industries that use a significant amount of stainless
steel.
In terms of welding nature, manual welding is considered
a traditional low-end welding process, typically used for
thinner stainless steel sheets and pipes. Nowadays,
electric arc welding has been replaced by laser welding,
which operates similarly to electric arc welding. Hand-
held laser welding can be performed by ordinary welders
with less than half a day’s training, making it a high-
potential replacement for traditional argon arc welding.

Conventional argon arc welding operation
It is a trend that laser welding replaces argon arc
welding.
Argon arc welding typically requires welding wire to be
melted and joined, resulting in a protruding welding
interface. In contrast, laser welding doesn’t need
welding wire, resulting in a relatively smooth interface.
Argon arc welding has been developed over many years and
is the most widely used welding process. Laser welding,
on the other hand, is a newer process that is rapidly
developing, but still represents only a small part of the
total welding industry.
It is an inevitable trend for laser welding to replace
some of the argon arc welding applications.
Currently, argon arc welding is still very popular due to
its low cost of use.
A welding machine for argon arc welding can be purchased
for thousands of yuan, with some cheaper models costing
only around 2,000 yuan. In addition, supporting products
such as small welding guns, welding wire, and argon are
priced at less than 1,000 yuan, with the cost of a
complete set being approximately 3,000 yuan.
In early 2019, hand-held laser welding equipment cost
more than 150,000 yuan per unit. However, with increased
competition, there are now many manufacturers of hand-
held welding equipment, and 1 kW models can be purchased
for around 60,000 yuan.

Welding: Which is the Future of Welding? 5
Handheld laser welding is faster
Argon arc welding only selects fixed positions at the
corners of the material for spot welding in order to save
labor and materials, while laser welding utilizes zipper
welding along the seam.
Compared to argon arc welding, laser welding provides
better firmness.
Handheld laser welding equipment with power segments of
500 watts, 1000 watts, 1500 watts, or even 2000 watts is
commonly used for welding thin plates and steel sheets.
Nowadays, handheld laser welding equipment is becoming
more compact, including necessary chillers that can be
integrated into the whole chassis to achieve integration.
This equipment has good mobility and much lower
procurement costs than before.
It can meet the requirements of a large number of metal
processing stores and processing plants and can even be
taken to the construction site for on-site operation.
