This day, I passed a welding shop, and I saw 6 welders so busy welding cars, trucks, cabs, and motorcycles. Do you think, this could be operated by both males and females? Does it require me to get training or hire only expert welders? For me, it is a good business because there are cars and buses this time. Welders could also be invited to enter a building to do welding steel bars. Have you tried this business?
