Laser Welding vs. TIG Welding ! Most Satisfactory Factory Machines

Laser Welding vs. TIG Welding Hello, everyone. There are many different types of welding. TIG welding, MIG welding, electric welding, CO2 welding, laser welding, etc. And each welding method has its advantages and disadvantages. Each of them has different uses as well. TIG welding is especially used when welding thin materials. Also, TIG welding is often used when high-quality welding is required. Because they have the right advantages in this area. However, as times change and technology advances, good machines and good technologies are being developed. One of them is a laser welder. Laser welding is also a welding method that has the appropriate advantages in this field. It has special advantages especially for precise welding. So what are the differences between TIG welding and laser welding? Today, I'm going to make a very simple comparison between these two welds. So this is stainless steel flat iron with a thickness of 3 mm thick. Perhaps the most common welds we use on the shop floor are "butt welds" and "fillet welds". First, let's compare "butt welding". I'll show you the laser welding first. Laser welders have many functions. Various languages are also supported. I'll introduce these things in more detail later. So this is how it's welded. Next is TIG welding. It seems that you should try welding with a width similar to that of a laser welding bead. For that, I think a low current would be good. 1 2 3 4 So, this is how it was welded. I didn't use a welding rod. I tried welding with a similar width. If the TIG welding current had been increased, the welding speed would have been a little faster. However, we tried welding with similar weld bead width for comparative test. As a result, there is a slight difference in work speed. And the most noticeable part is the weld bead color. Laser welding is close to golden color. And TIG welding seems to be close to the blue color. It means that TIG welding had more heat input. Maybe if we used "pulse welding" or "cold welding," we could reduce the heat input even more. However, it seems that the heat input is not relatively low during normal straight welding. Compared to the size of the material, the amount of heat input is high, so there is a lot of bending due to heat. It's a lot bent from the front and from the side. In contrast, laser welding has a small heat input. As a result, the bending caused by heat is relatively small. Since the heat input is small, it seems to be very advantageous for welding thin sheets. Now, let's do "fillet welding." Both were set up close to a 90-degree angle. What are the differences when doing "pillet welding"? Let's compare this too. I'm going to do laser welding first. This time, I'll use a wire to weld it. So it's welded like this is how it's welded. This time, I'll try TIG welding. 1 2 3 I'm going to increase the current a little bit and weld it a little faster. 1 2 I welded it like this. As you can see, there are these differences when you try to do something similar in simple situations with precision welding. Both welding methods allow for precision welding. Of course, depending on the techniques, there are likely to be some variables. In terms of quality, both are good. If you make a difference, you can give a higher score for laser welding. However, there is a big difference in terms of speed. Laser welding is much faster. Increasing the TIG welding current will speed up the operation a little. However, increasing the current also increases the amount of heat input. There is also a difference in the amount of heat input. There seems to be a difference in bending due to welding heat. There are these differences. This does not mean that TIG welding is bad. TIG welding can be used in many fields. It's a welding method that has a lot of advantages. However, in the situation I showed you today, laser welding seems to have an excellent side. Laser welding is likely to have overwhelming superiority if applied to mass production processes in similar situations. In addition to what I showed you today, laser welding has many functions. I'll introduce those to you later. Of course, I will introduce you to various methods of use and comparison tests later. So, that's all for today... If today's video was useful, please "Like 👍". So, let's finish this today and come back with another content next time. Thanks for watching.
