Robot laser automatic welding is a modern welding method
in which the robot will use laser welding head to weld on the workpiece.
It is suitable for various industries, including non automotive industries.
Although this technology has advantages in many aspects,
it also has some inevitable difficulties that require relevant personnel to solve.
In this article, we will discuss the difficulties in
the application of robot laser automatic welding in general industry (non automotive industry).
The first issue faced by the application of robot laser automatic welding
in general industry (non automotive industry) is the diversity of materials. Different types,
thicknesses, and shapes of materials require different welding parameters and welding joints,
thus requiring extensive engineering and design work to ensure correct welding results.
If the welding parameters are not correct, it will lead to poor welding quality,
welding defects, and poor weld quality, affecting the quality and performance of the product.
The second problem is the precision of laser Robot welding welding head.
Laser Robot welding heads have very high welding accuracy,
but they may have some problems on workpieces of different shapes and sizes.
Factors such as robot direction, welding speed, and welding angle can all affect
the positioning and accuracy of welding joints. Therefore, for the welding of large
or complex components, multiple welding operations and high-precision calibration
are required to ensure that the final welding quality meets the requirements.
The third issue is the optical imaging function. In order to ensure
the correct welding process, laser welding joints need high-speed imaging of the welding area during
the working process. However, the reflectivity of different material surfaces
and various welding scenarios require different imaging methods,
and appropriate imaging techniques and light sources need to be selected for different scenarios.
Incorrect imaging techniques may lead to welding deviation and even damage to the welded joint.
The fourth challenge is materials with strong reflectivity,
such as copper, gold, silver, and other materials.
The reflective ability of this metal material is strong,
which is easy to interfere with the laser welding joint and cause
welding failure. To overcome this problem,
it is necessary to use high-power lasers or increase the number and sensitivity
of reflective traps to ensure welding quality.
The final challenge is security. Robot laser automatic
welding requires strict safety measures to ensure the safety of operators and equipment.
The processing of laser radiation and high voltage areas is very important.
During the welding process, the actions of the robot and the rotational
speed of the welding head can both cause harm. Safety must be fully
considered in equipment design and operational specifications.
In a word, the difficulties in the application of robot laser automatic
welding in general industry (non automotive industry) include material diversity,
the accuracy of laser Robot welding head, optical imaging function, reflective materials and safety issues.
In the design, engineering, operation, and implementation of each specific welding project,
it is necessary to leverage the advantages of teamwork and multi-party
cooperation in order to overcome these challenges and achieve high-quality welding.
