Welding is an essential process for many industries, and the ability to join different materials together is a valuable skill. Knowing what welding processes can and cannot do can be tricky, as there are several factors to consider. In this blog post, we’ll take a closer look at whether or not you can TIG weld mild steel with stainless filler.
TIG welding, also known as Gas Tungsten Arc Welding (GTAW), is a type of welding that uses an electric arc formed between a non-consumable tungsten electrode and the metal being joined. It is often used to weld thin sections of stainless steel and other non-ferrous metals such as aluminium and copper alloys. The process requires the use of a shielding gas to protect the weld from oxygen contamination, which can cause porosity in the weld area.
When it comes to joining mild steel and stainless steel together, many people consider using different types of filler material. Mild steel filler is typically used when welding mild steel components together, while stainless fillers are often used when joining dissimilar materials such as aluminum or magnesium alloys with stainless steel components. However, when it comes to joining mild steel with stainless steel components, it is usually best to use a mild steel filler specifically designed for this application. This helps ensure that any heat-treatable properties in the base material are not affected by the filler material during welding.
While it is possible to use a stainless filler when TIG welding mild steel components together, it should only be done for repair applications where strength requirements are minimal, and heat-treatable properties need not be considered. If greater strength or higher temperature properties are required from the weldment, then stick welding with mild steel electrodes should be employed instead.
Conclusion:
In conclusion, you can TIG weld mild steel with stainless filler, but there are some caveats to consider before doing so. For applications requiring higher strength or better temperature properties then, stick welding with mild steel electrodes should be used instead. Understanding how each type of welding process works will help you make an informed decision about which process is right for your specific application needs. With proper care and attention given to both pre-weld preparation and post-weld finishing steps, you can create strong and reliable joint connections even when using dissimilar materials like mild steel and stainless steel together in your weldments!
