Just to address the issue with respect to safety, there is a welding standard, CSA W117, I believe, that specifically states how women in welding trades are to be protected, or how every employee should be protected, in terms of emissions from welding fumes. Ventilation equipment needs to be installed. Protective headgear needs to be worn. Respirators and other initiatives need to be taken into account.
