English: Instagram: carlitos_soldadurascls Material: 2mm sheets: approx. 60 amps. 4mm sheets: approx. 110 amps. 12 ceramic. Argon 12 L/min. Aluminum sheet. The role of aluminum in welding thin stainless steel is very important; we are talking about thicknesses of 1 mm, 1.5 mm, 2 mm, etc. Stainless steel is a very sensitive material and the work must be done carefully and well, since it is better not to touch it with the angle grinder to avoid having to polish it to remove scratches. This is a small example of how this process is done without contaminating the other side of the sheet. The weld can also be done by welding on one side and putting argon on the other side, this will protect us and there will be no contamination. I hope you liked the video.
