Cleaning Alcohol for Weld Seams

Cleaning alcohol to degrease metal surfaces before welding, to avoid hydrocarbon-induced porosity and cracks. It evaporates without residue.

Physico-Chemical Action Mechanism

Cleaning alcohol is a volatile solvent that dissolves and removes hydrocarbons from metal surfaces. As it evaporates, it leaves no residue on the surface.

Metallurgical Relevance & Welding Risks

Hydrocarbons can cause porosity and cracks during welding, affecting weld strength. Careful cleaning with cleaning alcohol can minimize this risk.

Workshop Practice & Instructions

Use cleaning alcohol in a spray can or a liquid cleaning machine. Spray the surface thoroughly and let it dry well before welding. Make sure no liquid remains in the weld pool, as this can lead to corrosion.
