But do note – Moisture is a serious concern in metalworking, and though the welding gear you may be wearing is built and designed to negate the effects of electricity when it gets wet (even with your own sweat) all its shielding capabilities are severely compromised.

Can you stick weld metal?

Technically, yes, you can. As per OSHA (Occupational Safety and Health Act), it is not illegal to stick weld when metal is wet or when it’s raining. However, we all know that water and electricity do not mix. So how do welders go around this? They avoid contact with the electrode and arc, eliminating any chances of electrocution.

Is welding in water dangerous?

The truth of the matter is that welding in the presence of water increases the chances of being electrocuted. There are, however, a number of ways that welders keep themselves safe. On an urgent deadline, instead of letting the money bypass them, they take some safety measures.

Does OSHA ban welding in water?

That said, OSHA does not ban the use of electrical (arc) welding equipment in the presence of water. Employers are, however, required to provide a safe space for work for their employees. This should be a working space free of hazards that could lead to potential physical harm. They, therefore, comply by providing safety equipment and protective gear in such situations.

Is it illegal to weld on wet metal?

It is, therefore, not illegal to weld on wet metal or when it’s raining, but employers should seek a solution to protect against electrocution and prevent damage to the welding equipment.
