The reconstruction of the Metro Bridge is a project where every weld directly affects safety. When part of the structures is welded directly above the water, on pontoons, the requirements for welding equipment and electrodes become even higher. Under these conditions, PATON welding machines and UONI-13/55 electrodes are used at the site in Kyiv. The

Last week, PATON held two online training sessions for sales teams from partner stores across Ukraine. This is part of our systematic effort to ensure that every customer looking for welding equipment receives professional advice and is guided towards the right solution for their specific application. Welding equipment is a complex product category. Different product

Welding undercut is a common weld imperfection that appears as a groove melted into the base metal along the weld toe and left insufficiently filled with weld metal. It can occur in fillet and groove welds. Even when the bead looks neat, undercut in welding can create a local stress concentration. Correct amperage, voltage, arc

Overlap in welding is a weld imperfection in which molten filler metal flows beyond the weld toe or root and solidifies on the base metal without properly fusing to it. It can look like an extra lip beside the bead. Although it may appear cosmetic, weld overlap can reduce joint quality because the deposited metal

Porosity in welding is a common defect caused by gas becoming trapped in molten metal as the weld solidifies. It may appear as small surface pinholes or remain hidden inside the bead. Welding porosity can reduce weld quality, especially when pores are concentrated, aligned, or combined with other defects. Weld cracking is different, but both

A weld is more than the visible bead on the surface. Every welded joint has several features that affect strength, fusion, penetration and overall profile. Understanding the parts of a weld helps welders read drawings, inspect finished work and describe problems accurately when adjusting technique or welding parameters. The main components include the weld face,

Stick welding, also known as SMAW or MMA, is valued for its simple equipment, portability and ability to work in workshops, on construction sites and outdoors. However, the process can be demanding for beginners because the welder controls the electrode, arc length, travel speed and angle manually while the rod continuously becomes shorter. Small changes

Shielded Metal Arc Welding, usually shortened to SMAW and commonly called stick welding, is a manual arc welding process used for fabrication, construction, maintenance and repair. In the UK, it is also widely known as MMA or Manual Metal Arc welding. The method uses a flux-coated consumable electrode that carries current to the workpiece, creates

Galvanised steel is widely used because its zinc coating helps protect the base metal from corrosion. The same coating that improves durability also creates an additional hazard during welding. When zinc is heated by an arc, it can vaporise and form zinc oxide in the welding fumes. This means anyone asking can you weld galvanised

Welding creates intense heat, bright arc radiation, hot metal, sparks, spatter, fumes, and noise, so personal protection is part of the process rather than an optional extra. The right welding PPE reduces exposure to hazards that can injure the eyes, skin, lungs, hands, feet, and hearing. It also helps the welder work more confidently because
