Summary
I am a seasoned Welder / Engineering technician with experience in many different welding and metal fabrication operations including TIG, MIG, FCAW, SMAW, Plasma Cutting, Torch Cutting, Air-Carbon Arc Gouging, Torch brazing, and Furnace brazing. Under minimal supervision I can precisely and safely ensure that I use the proper materials and/or processes in order to complete a job to it's desired specification. I have a versatile understanding of all types of shop equipment and machinery with the skills to operate and produce in a timely manner. I possess 6G GTAW certifications in both Stainless steel and Aluminum. I also possess a 3G/4G SMAW structural certification. I have a very good understanding of metallurgical concepts as well as the different methods of altering the properties of different metals.
