1. Preparation:
• Prepare the stainless steel pieces for welding. Clean the pieces and remove rust and dirt. You can use a steel brush and appropriate cleaner for cleaning.
• Position the pieces correctly and use clamps or magnets to secure them.

2. Welding Machine Settings:
• Select the appropriate welding machine for the welding process (TIG or MIG).
• Configure the machine with the correct voltage and amperage settings. These settings typically vary based on the thickness of the material and the welding type. Refer to the welding machine's user manual.

3. Wear Protective Equipment:
• Wear appropriate protective equipment to protect your eyes and skin during the welding process. This equipment may include a welding mask, gloves, work clothes, and goggles.

4. Welding Gas Setup:
• For TIG welding, use argon gas and set the gas flow rate correctly.
• For MIG welding, select the appropriate gas mixture and adjust the gas flow rate.

5. Welding Process:
• Before starting the welding process, turn on the welding machine and select the electrode or wire for welding.
• Conduct a few test welds to check the settings before starting the actual welding.
• Begin the welding process and slowly create the weld bead. Stainless steel should be welded at low temperatures, so you may need to progress very slowly.
• Keep the electrode or welding wire in the correct position during the welding process and maintain control over the welding pool.
• Once the welding process is complete, turn off the welding machine.

6. Cleanup:
• After the welding process, clean the weld bead and grind any excess welding metal as needed.
• Use acetone or thinner to clean any residue on the surface. 

Stainless steel welding is a skill that requires practice. You can start with small projects to gain experience and improve your skills over time. It's important to observe safety rules during the welding process, so be sure to use protective equipment and exercise caution.
