Stick Welding Stainless Steel To Carbon Steel

I m self taught starting with a terrible harbor freight stick welder but recently moving up to the lincoln welder you show in your picture above.

Stick welding stainless steel to carbon steel.

Welding differing materials such as stainless steel and carbon steel can be a much more economical choice than fabricating a structure entirely with stainless steel. Welding for the same heat or less heat input for the same speed. When welding stainless steel to a dissimilar metal such as plain carbon steel weld processes such as mig welding that use filler material are preferred. To ensure stainless steel doesn t get warped you ve got to make a proper choice for a shielding gas.

A solid wire electrode is perfect for creating a strong stainless steel join as it ll form better than other compound based electrodes. My welding dramatically improved with this machine. Swanton used e309 as it is the commonly used filler metal for joining mild steel to 304 stainless steel. Comparison of welding characteristics of type 304 stainless steel with carbon steel carbon steel type 304 remarks melting point 2800 2550 2650 type 304 requires less heat to produce fusion which means faster ºf approx.

Depending on the type of work you do there may come a time when you have to weld dissimilar metals together. This type of activity often involves the use of a welding method known as metal inert gas mig welding which helps to create a strong bond between the stainless steel and the carbon steel the process will also call for making use of specific grades of welding rods based on the grades of the two. In this episode we discuss welding 304 stainless steel to a36 mild steel using smaw. The stainless was a solid piece of 4 round that was drilled out 2 1 2 and threaded leaving approx 3 4 side wall.

Welding carbon steel to stainless steel is a common process in the creation of a number of goods. The welding of dissimilar materials is common in certain power generation facilities such aspetrochemical refineries as well as in many mining and mineral processing facilities. Stainless electrodes with higher alloy content are used so the admixture of the mild steel into the stainless weld deposit does not form an unsatisfactory alloy. Stainless steel is susceptible to heat distortion when placed under very hot temperatures.

I need to weld stainless to carbon steel. Austenitic stainless steels such as grade 304 stainless or grade 316 stainless can be welded to plain carbon steel using mig and tig welding. I believe the stainless is 304 and the carbon steel is a36. The piece of a36 is 1 2 thick plate with a 2 1 2 hole to line up with the stainless.

This process is very common in structural applications where a steel connection needs to be joined to stainless steel.
