Heat-resistant suits and gaiters for welders. What to look for when buying?

Any kind of welding is melting metal. Thermal radiation, sparks, toxic fumes and spray hot — is not a complete list of negative impacts faced by the welder. Therefore, to ensure safety during the works the great attention is paid to the choice of equipment. Heat-resistant suits, leggings and other protective equipment must be not only reliable and durable but also comfortable. What should pay attention when choosing them?

Construction features protective suits

Overalls for welding has a straight fit and does not hinder movement in any position of welder, has a special design corresponding to a certain standard. Costumes can be made in the form of overalls, coveralls or pants complete with a jacket, which should close the pants in any position of working not less than 20 cm Clasp necessarily complemented by straps or valves, the maximum distance between them is 150 mm.

To spatter did not stay on the dress — bottom of pants and sleeves of jackets are without lapels. For this reason, all external pockets are protected by flaps. The exception is located below the waist the side pockets, with the entrance to 10 ° relative to the side seam. In the high-end models protection on the collar and cuffs are sure to put the clasp.

Protection classes

Heat-resistant suits must be marked with the designation protection class according to GOST 12.4.250-2013:
— Class I — sets intended for operators of automatic welding lines or equipment and installation for mechanical cutting of metal; distance to source hot spray not less than 2 m.
— Class II — heat resistant suits to perform different types of manual welding in workshops, field and installation conditions; distance from the worker to the source metal spatter and slag — in the range of 0.5 m.
— Class III — types of workwear, focused on the most severe welding conditions in a restricted volume of areas, including tanks, pipelines, etc.


Welding overalls are made of different materials, the total quality which is the resistance.

  • Costumes from the innovative cotton fabrics and cloth. The cotton fibers provide good vapour exchange, contributing to comfort during the execution of the works. PROBAN technology involves the processing of the fibers the polymer solution at the stage of production, whereby the material acquires the highest index of resistance. Thanks to impregnation and sateen weave splashes and sparks falling from the clothes, without compromising the integrity of the fabric.

  • Canvas suits. Are made from a material with a density of 400-600 g/m2, composed of linen and cotton thread. To increase fire resistance, the fabric is further treated by impregnation, and also reinforce with additional layer of material at knees, elbows, the front parts of the shelves.

  • Costume of split leather or genuine leather. Zelenopillia models are made from one of the middle layers of the skin, obtained by surfowanie. This material is very dense leather, protects welder from molten metal splashes and other negative impacts weld, but poorly breathable. Therefore, these materials are often used for reinforcing pads on the canvas suits or for the manufacture of the Krag with the highest index of resistance.

All kinds of heat-resistant overalls are sewn together with special reinforced threads that are resistant to open flames and high temperatures. The suits of the welder from a special innovative fabrics, and other items of workwear welder can be found in “SOYUZSPETSODEZHDA”. Feature of these products is the ability to maintain flame resistant properties throughout the entire period of operation.

For warming winter options of suits of welders continues to be a priority material is batting. A natural material made from a mixture of secondary wool yarn, synthetic and cotton fibers, has excellent insulating properties, both at high and at extremely low temperatures, while the batting is much worse at trapping heat in extreme conditions and is afraid of exposure to open flame.


According to GOST length welder’s gloves must not be less than 35 cm. the Best material for the manufacture of the Krag is considered beef cattle, processed by special trains. The advantages of material — immunity to temperature effects and increased strength along with high ductility.

For durability gaiters are stitched with fire retardant Kevlar thread; when used for the firmware Dacron sutures are further amplified leather inserts. To increase the insulating properties inside sewn fleece or cotton lining. In the combined models are reinforced Spilka inserts on the Palmar area and textile on the back.
Select the leggings, given the nature of use. Five-fingered gloves made of split leather — a versatile option, do not reduce the mobility of the fingers and therefore are used for fine work. Two – and three-toed leggings are often made from extra thick canvas, they are intended to reduce the load on the hands of the welder, good resistance to high temperatures, but do not protect from punctures.
