How to protect the welder ？

As we all know, welding work is very dangerous, so when welding, To be sure to do a good job of personal protection.So what should be done to protect the welder? C&Ge editor summarizes 3 major elements.

First of all , the professional protective glasses, gas mask, mask, glove must be used when welding, wear shoe of electric welding protective suit, insulation, must not wear short sleeve garment or roll up sleeve, if welding environment is ventilated, must wear the long tube breathing apparatus that uses performance to send wind or air breathing apparatus.

Second, we should strive to improve the welding process by improving the welding technology, so that the welding operation to achieve mechanization, automation, and isolation of the welding environment, fundamentally eliminate the harm of electric welding operations on the human body.By improving the welding process, such as reasonable design of the structure of the welding vessel, the use of single-side welding, double-side forming new technology, avoid welders in the container of poor ventilation welding, so as to greatly improve the working conditions of welders.

Third, we should pay attention to the processing of the welding place, strengthen the welding place way of ventilation can be divided into natural ventilation and mechanical ventilation, the pressure generated by mechanical ventilation is to rely on fan to take a breath, dust removal, detoxification effect is good, and poor in natural ventilation room and closed container during welding, must have a mechanical ventilation measures.

Let's talk about welding gloves, welding protective clothing, welding mask, some requirements for welding safety.

Electric welding gloves must meet the following conditions:

(1) Welder's gloves should be made of wear-resistant and heat-resistant leather or cotton canvas and leather, and their length should not be less than 300mm. Welders should not wear damaged and wet gloves to make them strong.

(2) When welders work in the welding site which may be conductive, the gloves used should be made of insulating material (or additional insulating layer) and can only be used after passing the test of voltage resistance of 5000V.

The welding protective clothing must meet the conditions：

(1) Protective clothing used by welders should be selected according to the characteristics of welding and cutting work.

(2) Cotton canvas work clothes are widely used for general welding and cutting work.

(3) gas welding under the action of ultraviolet radiation, ozone and other gases should be used when tweed or leather fabrics made of work clothes, in order to prevent welders in the operation of scalded or increased temperature.

(4) All position welding welders should be equipped with leather work clothes.

(5) in the back welding cutting, in order to prevent Mars, slag from high sputtering to the head and shoulder, welder should be around the neck towel, wearing shoulder protection, long sleeve sleeve, apron and shoe cover made of flame-proof materials.

(6) welder wear work clothes should not be wet, work clothes pockets should cover the upper body should cover the waist, pants should cover the uppers, work clothes should not be damaged, holes and gaps, not allowed to touch oil and grease.

(7) Welding and cutting work clothes can not be made of general synthetic fiber fabric.

The welding mask must meet the conditions

(1) To prevent the harm of welding arc light and spark burns, according to the requirements of GB3609.1 "Welding Goggles and Masks", the shading lens that meets the operation conditions should be selected.

(2) welder's mask has two kinds of hand-held and head-worn, the shell of the mask and helmet should be made of non-combustible or non-combustible and non-stimulating skin insulation material, the cover body should cover the face and ears, the structure is firm, no light leakage.

(3) Head welding mask, used for all kinds of arc welding or height welding operations, the weight should not exceed 560g.

(4) According to the working conditions, the auxiliary welder should choose to wear mask and protective glasses with suitable shading performance.

(5) In gas welding and gas cutting operations, protective lenses of corresponding models should be selected according to the thickness of the welding and cutting workpiece plate.

(6) Welding, cutting preparation, cleaning work, such as polishing welding, cleaning slag, etc., should use the lens is not easy to break into a piece of slag glasses.

Welder safety shoes must meet the requirements

(1) Welder protective shoes should have insulation, heat resistance, non-flammable, wear resistance and skid resistance of insulating shoes.

(2) The rubber sole of the welder's protective shoes should pass the test of voltage resistance of 5000V. When welding on inflammable and explosive occasions, there should be no nail in the sole to avoid friction and spark.

(3) When welding and cutting on the ground with water, welders should wear waterproof rubber shoes with voltage resistance of 6000V and qualified test.

In general, the welding operation must protect yourself, do a good job of the relevant protection.
