Which is Better, Laser Welding Machine or Argon Arc Welding Machine?
Can laser welding completely replace argon arc welding? What do you think? Which is better, laser welding machine or argon arc welding? Now let's analyze our experience for everyone!
1. What is a laser welding machine?
Laser welding machine is a machine that uses laser welding. According to its working mode, it can be divided into laser mold welding machine, automatic laser welding machine, laser spot welding machine, optical fiber transmission laser welding machine and other models. Laser welding is the use of high-energy laser pulses to locally heat materials in a small area. The energy of laser radiation diffuses into the interior of the material through heat conduction, and the material is melted to form a specific molten pool to achieve the purpose of welding.
2. What is an argon arc welding machine?
Argon arc welding is tungsten inert gas shielded arc welding, which refers to a welding method that uses industrial tungsten or active tungsten as the non-melting electrode and inert gas (argon) as the shielding gas, referred to as TIG.
According to the different electrodes, argon arc welding machines are divided into two types: melting electrode argon arc welding machines and non-melting electrode argon arc welding machines.
Non-melting electrode argon arc welding is that the arc burns between the non-melting electrode (usually tungsten) and the workpiece, and an inert gas (commonly used argon) that does not chemically react with the metal flows around the welding arc, and forms a The protective gas cover keeps the tip of the tungsten electrode, the arc and the molten pool, and the metal at high temperature out of contact with the air, which can prevent oxidation and absorb harmful gases, thereby forming a dense welded joint with very good mechanical properties.
The metal argon arc welding wire is fed through the wire wheel, the conductive tip is conductive, an arc is generated between the base material and the welding wire, the welding wire and the base material are melted, and the arc and the molten metal are protected by an inert gas argon for welding.
The difference between it and non-melting electrode argon arc welding is that: one is that the welding wire is used as the electrode (melting electrode), and it is continuously melted and filled into the molten pool, and the weld is formed after condensation; the other (non-melting electrode) is the tungsten electrode as the welding electrode, and the welding electrode does not melt.
With the technical application of metal argon arc welding, the protective gas has developed from a single argon to a wide range of mixed gases, such as Ar 80%+CO2 20% argon-enriched protective gas. Usually the former is called MIG and the latter is called MAG.
From the perspective of its operation mode, the most widely used are semi-automatic MIGA welding and argon-rich mixed gas shielded welding, followed by automatic MIGA welding.
Therefore, it is better to use a laser welding machine for welding thin-walled materials, and for welding thick materials. If there is no high requirement for welding speed and welding accuracy, then it is more cost-effective to use argon arc welding machine, but if you do not care about the cost, using laser welding machine is still better.
