hitsaussuojakypärä

Hitsaussuojakypärä, also known as a welding helmet, is a piece of personal protective equipment (PPE) designed to protect the welder's face and eyes from the intense heat, ultraviolet (UV) and infrared (IR) radiation, sparks, and spatter produced during welding. It is a crucial safety item for anyone performing welding operations.

The primary function of a hitsaussuojakypärä is to shield the welder's eyes from the bright arc generated during welding. This arc emits high levels of UV and IR radiation, which can cause severe eye damage, including arc eye (photokeratitis), and long-term vision problems. The helmet's shade lens, typically made of tinted glass or polycarbonate, filters out these harmful rays. The degree of darkness, or shade number, is chosen based on the welding process and amperage.

Modern hitsaussuojakypärä often feature automatic darkening lenses (ADF). These lenses electronically sense the welding arc and darken instantaneously, providing consistent protection without the need for the welder to manually lower the helmet. This significantly improves safety and allows for easier positioning of the workpiece.

Beyond eye protection, the helmet's shell is constructed from durable, heat-resistant materials like polycarbonate or fiberglass, safeguarding the face and neck from sparks, hot metal, and potential burns. Many helmets also include a comfortable headgear that allows for adjustable fit and positioning, ensuring the helmet stays securely in place during welding. Proper use and maintenance of a hitsaussuojakypärä are essential for ensuring effective protection and preventing welding-related injuries.
