Which welding method is best for stainless steel?

In terms of practical performance in stainless steel processing, laser welding has the advantages of precision and efficiency, and is therefore better suited to the precise welding of thin sheets. However, traditional methods such as tungsten inert gas (TIG) welding still have advantages in the processing of thick sheets and in situations where costs are a concern.When choosing the right technology, one must take into account the thickness of the materials, the requirements of the product, and the budget. For export-grade products or for workpieces with a high demand for surface quality, laser welding is still the preferred option.

This is the core characteristic of laser welding.

Laser welding is like performing microsurgery on stainless steel, using a high-energy laser beam to melt the metal and achieve a precise weld.Compared with traditional welding, the heat-affected zone is so small that it is almost invisible, and the weld seam is perfectly flat. It is particularly suited to products that require a high degree of surface quality, such as tableware and medical instruments.

The speed of the change is beyond imagination.

For example, it takes five seconds to weld a 0.5-mm-thick stainless steel plate with a TIG welder, but a laser welder can do it in just one second.This kind of efficiency can save a company a lot of electricity and labor costs in mass production.

The space for traditional welding skills.

Despite the flashiness of laser welding, the old-timer TIG welding and the resistance welder haven't completely left the scene.For example, for a structure like an outdoor billboard stand, where there is no requirement for aesthetic appeal, the old-timers are still more comfortable with the TIG torch. After all, the investment in equipment is only a fraction of that required for a laser welder.

The test of welding thick plates.

When the thickness of the steel plate exceeds 8 mm, the laser welder must perform multiple welds. At this time, the submerged arc welder can complete the task in one fell swoop.But you have to be careful about deformation due to heat. After it's welded, you may have to put it in a hydraulic press to "set the bones.

How can you choose a product without falling into a hole?

If a product is to be exported to the U.S. or Europe, it is recommended that it be laser welded. The Westerners are very particular about the quality of the weld.If the budget is tight but you want to guarantee strength, you can try laser-MIG welding. This combination technique is cost-effective and can meet most needs.

The thickness of the material is a key indicator.

Remember this formula: For thicknesses of 3mm or less, close your eyes and choose laser welding; for 5mm or more, traditional craftsmanship is the way to go. For thicknesses in between, it depends on how deep your purse is.Of course, the choice of process must be combined with the product's application. For example, food machinery must use laser welding, which leaves no trace.
