How to Weld Stainless Steel to Mild Steel?

Technically, the chemical and mechanical composition of the base metals used in welding applications should match perfectly. However, in the fabrication, manufacturing and construction industry there are occasions where there is a need to weld dissimilar materials.

This includes welding different materials like stainless steel and carbon steel (mild steel). Since stainless steel is expensive, it is much more economical to use mild steel in combination with that for construction purposes.

Below are some of the factors to keep in mind:

1. Proper cleaning and preparation are the two most important steps that will help to ensure the successful welding of stainless steel to mild steel.
2. While welding stainless steel to mild steel it is of utmost importance to pay attention to the chemical and mechanical properties along with corrosion resistance to avoid potential trouble. Hence choosing the right filler metal is very important.
3. Following a suitable welding procedure that will limit the heat input of the weld and stainless steel material is very important. This will reduce the dilution of the weld deposit with the mild steel portion of the weld joint.
4. Avoid warping, cracking and oxidation by preventing contamination of the weld joint that will result in serious welding problems like hot cracking.

Welding stainless steel to mild steel can be challenging. Hence it is very important to have the maximum possible information about the characteristics of the base metals and the filler metals to make accurate choices that yield successful welds.
