Light duty. Are there any aspects of your day to day welding job that involves heavy lifting

I’m currently on light for a possible hernia or maybe an abdominal strain. but i want to leave my current job and move into the welding field. I have just got my aws certification and have already started looking for jobs. One is construction, warehouse steel, and one is for rebuilding trailers. The requirement is that new job has to follow my light restrictions of no lifting 15 pounds.
