Most people when they are welding will remove any paint or galvanising. This is because their presence (particularly gal) can cause problems with the strength of the weld. If the paint was left on, it will rapidly vapourise under the extreme heat. Some molucules of the paint may be incorported into the well, but most would disappear into the atmosphere. Which chemicals were involved would be dependent upon the type of paint. As to the danger from these chemicals, probably some where between slight and bugger all. It could be worth wearing a air filter underneath the welding mask. Can we ask what this is in relationships too. So we can provide a better answer.

By this I meant, are you a homehandy man welding this material or do you work in a ship building yard, with hundreds of welders working. Is the area well ventilated. Is the paint that is being effeced by the welding, acrylic based, lead based, cold gal paint etc. The more details you can provide the better.

Apart from the previously mentioned quality of the weld, the fumes produced can be very toxic. If the paint contained lead, so do the fumes. The likely headaches most paints will give you are not worth it. This forum is un-moderated. The views and opinions expressed are those of the individual poster and not the ABC.
