Maintenance and repair welding onboard involves a host of unknowns. Problems relate to chemical composition of the base metals, weldability, pre and post heat, choice of electrode, and the handicaps of field welding.

PROTECT THE EYES
Never expose bare eyes to the glare and rays from the ARC! This will cause arc-eye (very painful) and damage to the ayes. Use filter glass of correct grade.

What about your welding technique? Could you need a bit of time at the welding school?

Both welding cable and return cable should be stretched to the welding site Remember that if you connect the return cable in the ships structure you are actually standing on the return current

Place the return clamp as near to where the welding takes place as possible. If you don’t, the return current might travel through ball bearings and other critical machine parts and destroy them.

If you are a smoker remember that disposable plastic cigarette lighters kept in pockets may cost you your life on a welding job. Should a spark fall into your pocket the lighter may explode, resulting in extensive, even fatal burns. Always leave your lighter behind when you shall weld.

Remember that protective clothing is not only meant to protect you from burns spatter and arc radiation but also serves as an insulator so you don’t become part of the electric circuit

Hoses and cables should be kept clear of passage ways.

To work with worn or damaged welding cables is extremely dangerous. Inspect the condition of the cables regularly. Worn cables should be replaced, not “Repaired” with insulation tape. If the damage is local the damaged part should be cut away and the cable joined with a cable connector.

DO NOT lean directly on to the structure if the return current runs through it, but make sure to insulate yourself using either a RUBBER MAT or WOOD.

Poisonous gas might develop during welding caused by elements in the base materials or due to paints and metal coatings on the surface.

HAVE ELECTRODES BEEN PROPERLY STORED?
If electrodes are left in the open air they start to attract moisture. When the electrode is used the moisture in the coating goes over as Hydrogen Porosity in the weld. This will in time develop into Hydrogen Cracking.
