Supplies for Shipyards

The MIG (wire-feed) welder is easy to use on steel and thin materials, with a continuous wire. The multi-process machine lets you switch from one process to another and works on different materials. The choice depends on the thickness of the material and the current required. Check the power supply available on the site or in the workshop and the duty cycle stated by the manufacturer.

The auto-darkening helmet protects the eyes from the light of the arc and darkens as soon as the arc is struck. It must comply with the EN 175 standard on eye and face protection during welding. Choose the shade level according to the process and the current. Check that the lenses are clean and free of scratches, and replace the filter when it stops responding.

The electrode holder grips the electrode and carries the welding current. The earth clamp completes the circuit with the workpiece and must be fixed to a clean surface. Welding cable connectors must have the right cross-section so that they do not overheat. Check that cables and holders are intact, with no exposed parts, and keep connections away from water.

The grinding disc works welds and removes burrs after cutting. The aluminium oxide (corundum) or silicon carbide disc suits steel, stainless steel or cast iron, depending on the material. Finishing discs are better for surfaces to be finished. Choose the disc according to the material, the maximum speed indicated and the tool, and always fit the guard.

The motorised sandblaster removes rust, paint and encrustations with an abrasive blast, while the pressure washer cleans and degreases without abrasion. For a hull, the choice depends on the condition of the surface and the risk of damaging the material underneath. Sandblasting produces dust and requires respiratory protection. Wear a coverall, safety glasses and a suitable respirator and work in a cordoned-off area.

Anti-spatter spray for welding stops metal spatter from sticking to the nozzle and the workpiece. Fibreglass filler repairs small defects before finishing. Fibreglass resins require gloves, safety glasses and adequate ventilation, because they emit vapours. Read the safety data sheet and respect the curing times given by the manufacturer.

The fibreglass repair kit contains resin, catalyst and cloth to rebuild a small damaged area of the hull. For marine rope, polyester braid is resistant to UV rays and salt water. Choose the diameter of the braid according to the load and the use, and check the rope before each outing. Work in a ventilated area and with the PPE (personal protective equipment) indicated in the datasheet.
